The main characteristics of 2BE1 series products:
All the bearings are the imported products with the brand name of CHINAMFG orNTN for ensuring the precise orientation and the high stability during the working of the pump.
The material of the impeller is QT400 nodular iron or stainless steel for ensuring the stability when the pump works under the rigorous condition and can extend the lifetime of the pump.
The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE1 series pumps.
The shaft bushing is made of stainless steel to improve the lifetime of the pump 5 times than the normal material.
The V-belt pulley (when the pump is driven by the belt) is used the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle.
The coupling is used to drive the pump directly. The flexible part connecting the 2 half coupling is made of polyurethane that makes the pump more reliable.
The unique design to set the separator above the pump saves the space and decreases the noise efficiently.
All the parts are cast by the resin sands that make the pump surface very smooth. It is not necessary to cover the surface of the pumps with putty and gives out the heat efficiently.
The mechanical seals (optional) are used the imported products to avoid the leakage when the pump works for a long time.

What is the difference between a piston and rotary screw compressor?
Piston compressors and rotary screw compressors are two common types of air compressors with distinct differences in their design and operation. Here’s a detailed explanation of the differences between these two compressor types:
1. Operating Principle:
- Piston Compressors: Piston compressors, also known as reciprocating compressors, use one or more pistons driven by a crankshaft to compress air. The piston moves up and down within a cylinder, creating a vacuum during the intake stroke and compressing the air during the compression stroke.
- Rotary Screw Compressors: Rotary screw compressors utilize two intermeshing screws (rotors) to compress air. As the male and female screws rotate, the air is trapped between them and gradually compressed as it moves along the screw threads.
2. Compression Method:
- Piston Compressors: Piston compressors achieve compression through a positive displacement process. The air is drawn into the cylinder and compressed as the piston moves back and forth. The compression is intermittent, occurring in discrete cycles.
- Rotary Screw Compressors: Rotary screw compressors also employ a positive displacement method. The compression is continuous as the rotating screws create a continuous flow of air and compress it gradually as it moves along the screw threads.
3. Efficiency:
- Piston Compressors: Piston compressors are known for their high efficiency at lower flow rates and higher pressures. They are well-suited for applications that require intermittent or variable air demand.
- Rotary Screw Compressors: Rotary screw compressors are highly efficient for continuous operation and are designed to handle higher flow rates. They are often used in applications with a constant or steady air demand.
4. Noise Level:
- Piston Compressors: Piston compressors tend to generate more noise during operation due to the reciprocating motion of the pistons and valves.
- Rotary Screw Compressors: Rotary screw compressors are generally quieter in operation compared to piston compressors. The smooth rotation of the screws contributes to reduced noise levels.
5. Maintenance:
- Piston Compressors: Piston compressors typically require more frequent maintenance due to the higher number of moving parts, such as pistons, valves, and rings.
- Rotary Screw Compressors: Rotary screw compressors have fewer moving parts, resulting in lower maintenance requirements. They often have longer service intervals and can operate continuously for extended periods without significant maintenance.
6. Size and Portability:
- Piston Compressors: Piston compressors are available in both smaller portable models and larger stationary units. Portable piston compressors are commonly used in construction, automotive, and DIY applications.
- Rotary Screw Compressors: Rotary screw compressors are typically larger and more suitable for stationary installations in industrial and commercial settings. They are less commonly used in portable applications.
These are some of the key differences between piston compressors and rotary screw compressors. The choice between the two depends on factors such as required flow rate, pressure, duty cycle, efficiency, noise level, maintenance needs, and specific application requirements.

Choose an Air Compressor for Your Business
There are several factors to consider when choosing an air compressor for your business. One factor to consider is the type of compressor you are looking for, which may include single-stage, low noise, and positive displacement. Hope this article helps you make the right decision. After all, your business success will depend on this device! Let’s take a closer look at these factors. Also, consider what compressor manufacturers say about their products.
Positive displacement
Positive displacement air compressors compress air by drawing in a volume from an inlet and extruding it out of a chamber. This increases the pressure at which the gas can be pumped at rates that cannot be pumped through the outlet at lower pressures at higher mass flow rates. These types of compressors are available in single-acting and double-acting configurations. They are classified by the number of cylinders.
There are two different types of air compressors: reciprocating air compressors and screw compressors. Both are roll machines. Positive displacement air compressors use pistons and cylinders to compress air. The resulting air pressure builds up within the compressor housing, increasing the potential energy of the compressed air. Screw air compressors are the most popular positive displacement air compressors, which can be either single-stage screw-blade air compressors or multi-stage screw-blade oil-immersed screw air compressors.
Positive displacement flowmeters use a rotating measuring chamber to divide the fluid into discrete quantities. The number of times the chamber was refilled and emptied was used to estimate the total flow. However, positive displacement flow meters are prone to leaks, reducing the accuracy of the estimates. If a leak occurs, it can cause false readings and damage the compressor. However, leaks in positive displacement air compressors can reduce pressure.
The most common types of positive displacement air compressors are screw, reciprocating, and vane. Rotary positive displacement air compressors are also available as well as many other air compressors. Positive displacement air compressors are most commonly used in large manufacturing facilities. If you are considering an air compressor for commercial or industrial applications, it is imperative to understand how the components of the unit work. Please read the information below to learn more before deciding which application is best for you.
Positive displacement air compressors use a piston to force air into a chamber, compressing the air in the process. The piston moves in the opposite direction, thereby reducing the volume of the chamber. When the amount of air in the chamber reaches its maximum value, the valve opens, allowing it to escape at higher pressure. Positive displacement air compressors are generally less efficient than centrifugal compressors. However, they are still an excellent choice for a variety of applications.
Single-stage
The discharge pressure of the single-stage air compressor is used to control the operation of the compressor. Properly designed load/unload controls allow the air compressor to operate at its most efficient point while minimizing stress on the main engine bearings. Single-stage air compressors can approach variable speed efficiency with appropriate storage capacity. However, improper storage can cause premature bearing wear on the main unit. If this is the case, a single-stage air compressor may not be ideal.
A single-stage air compressor has only one cylinder, which means one stroke is required to move air from one cylinder to another. Pressure is measured in cubic feet per minute or CFM. Tank size is also important as a large single-stage air compressor may be required to operate multiple air tools. Single-stage air compressors can be used in a variety of applications and can last for years.
For the most common uses, single-stage air compressors are the most practical option. These devices work with most hand tools, from hammers to grinders. Single-stage air compressors are lightweight and easy to move. However, two-stage air compressors provide more CFM, making them a better choice for industrial or commercial use. However, two-stage compressors are not suitable for private use. Therefore, if your main purpose is DIY and craft projects, it is better to choose a single-stage air compressor.
Compared with two-stage air compressors, single-stage screw air compressors are cheaper. They come from a variety of manufacturers and range in power from 3 to 600 horsepower. Single-stage air compressors are a cost-effective solution for a variety of air compressor needs. They offer flexibility and multiple control methods, making them an excellent choice for many different applications. Therefore, when choosing an air compressor for your business, choose the one with the most suitable functions.
Single-stage air compressors are the most affordable and easy-to-use air compressors for small to medium jobs. They also have higher compression ratios. The compression ratio is the ratio of absolute discharge pressure to absolute inlet pressure. When calculating the ratio, it takes into account atmospheric pressure and gauge pressure. The compression ratio pushes the surface area of the rotor, which increases the thrust load.
Single-stage air compressors are smaller and easier to transport than two-stage units. Single-stage air compressors have one air intake, and two-stage air compressors have two air intakes. The difference between single-stage and two-stage air compressors largely depends on the number of times the air is compressed. A single-stage air compressor compresses the air once, while a dual-stage air compressor compresses the same amount of air twice.
low noise
Low noise air compressors are ideal for a variety of applications. While no air compressor is completely silent, some models are much quieter than others. For the Hitachi EC28M portable compressor, the noise level is 59 decibels. The compressor features steel rollers that protect the internal components and give it a sleek, modern look. It also has a one-gallon fuel tank and a half-horsepower drive.
Noise from air compressors can be distracting and reduce productivity. It is important to choose low-noise air compressors to keep employees healthy and happy at work. While noise is an unfortunate aspect of working on the shop floor, reducing it can improve productivity. By reducing distracting noise, employees can focus on their work and communicate more effectively. That means higher quality work and happier clients. If you’re looking for a low-noise air compressor, be sure to read the tips below.
Low noise air compressors are an excellent choice for businesses of all sizes. These powerful tools can run multiple tools simultaneously. The two water tanks are made of rust-resistant aluminum and are stackable. This air compressor is heavier and can handle large jobs with ease. It costs more than other air compressors, but it can handle a lot of work efficiently. CZPT Air Tools air compressors come with a one-year warranty and are highly recommended by contractors.
Noiseless air compressors are generally more expensive than comparable products, but they are worth the extra cost. Noiseless compressors are a good option for businesses that need to avoid disturbing nearby people. For example, you might want to consider a low-noise air compressor for a dental office, which cannot tolerate noise. Fortunately, this problem can be solved by relocating the compressor to a location that is more isolated from your workspace.
One brand of low-noise air compressors offers two models. The CZPT Air Tools 2010A features a large cast aluminum can, regulating pressure gauge, and two universal quick-connects. It produces 68 decibels of noise when it works. It has a large 8-gallon fuel tank capacity and has wheels and handles for easy transport. Its powerful engine produces a low noise level of 68 decibels.
Another popular low noise air compressor is the Makita MAC210Q Quiet Series. This model is capable of producing up to 71.5 decibels of sound, which is the amount of air it produces at 90PSI. The MAC210Q features a durable oil-free pump and weighs just 36 pounds with a handle and wheels. These compressors are easy to move and ideal for indoor work.

How to Pick the Proper Air Compressor
An air compressor utilizes pressurized air to electricity a range of tools. They are most typically utilized to electrical power nailers and affect wrenches. Other well-liked uses for air compressors consist of paint sprayers and effect wrenches. Although all air compressors have the identical fundamental building, their specialty differs. In the long run, their distinctions occur down to the amount of air they can press. Read on for information on every single type of air compressor. These equipment are wonderful for many different functions, and choosing the right air compressor is dependent on your certain demands.
Electric motor
Whilst acquiring an electric powered motor for air compressor, compatibility is a important element. Not all motors operate with the identical type of air compressor, so it is important to check out the manufacturer’s instructions ahead of buying. By performing this, you can steer clear of wasting money on an incompatible motor. Another crucial consideration is speed. A motor’s pace is its price of rotation, calculated in revolutions per minute. It is essential that you acquire a motor with adequate speed to meet the requirements of your air compressor.
Typically, an electric motor for air compressor is 1.5 hp. It is perfect for use with healthcare tools and metal-slicing devices. It also performs well below ongoing operation and provides a higher efficiency and strength-saving efficiency. In addition, it features an desirable price, generating it a excellent choice for a extensive selection of applications. If you are looking for a motor for an air compressor, seem no more than a ZYS series.
A motor’s safety course indicates how the motor will run. Protection lessons are specified by the IEC 60034-5. These are said with two digits and signify the safety in opposition to sound objects and water. For example, an IP23 ranking implies that the motor will be protected from solid objects, whilst IP54 signifies that it will shield from dust and drinking water sprayed from all instructions. It is important to choose a motor with the right security course for your air compressor.
When picking an electric motor, you should consider whether it really is suitable with the brand name of air compressor. Some may be compatible, even though others may possibly call for advanced electronics abilities to restore. Nevertheless, most air compressors are protected by guarantee, so it truly is critical to check out with the maker if the guarantee is nonetheless in impact just before you commit a dime on a substitution. The motor need to be replaced if it has unsuccessful to execute as developed.
Oil tub
Air compressors need appropriate lubrication to purpose proficiently. The piston should attract air with small friction. Based on their design, air compressors can both be oil-lubricated or oil-cost-free. The former employs oil to minimize piston friction, although the latter splashes it on the cylinder bearings and walls. These kinds of air compressors are frequently known as oil-flooded air compressors. In order to maintain their oil baths cleanse, they are advised for use in places with large dust stages.
Commence/stop manage
An air compressor can be controlled by a commence/end management. This type of control sends a signal to the principal motor that activates the compressor when the need for air falls below a preset limit. This manage technique is successful for smaller air compressors and can be helpful for minimizing strength fees. Commence/cease handle is most efficient in apps exactly where air pressure does not change frequently and the place the compressor is not necessary to operate continuously.
To troubleshoot this difficulty, you want to examine the electrical power provide of your compressor. To verify the provide side, use a voltage check to decide if energy is flowing to the compressor. Make certain that the power supply to the compressor is regular and secure at all moments. If it fluctuates, the compressor may possibly not begin or cease as envisioned. If you cannot find the dilemma with the air compressor electrical power supply, it may possibly be time to change it.
In addition to the start/stop management, you may want to acquire added air receivers for your air compressor. These can boost the potential of air stored and lessen the variety of moments it starts off and stops. Another way to decrease the amount of commences per hour is to add a lot more air receivers. Then, you can adjust the manage to match your demands. You can also put in a strain gauge that monitors the compressor’s performance.
Start/stop handle for air compressors can be intricate, but the standard elements are reasonably simple to comprehend. 1 way to test them is to flip the compressor on or off. It is usually situated on the exterior of the motor. If you are not sure of the location of these factors, examine the capacitors and make positive that the air compressor is not managing whilst you are not making use of it. If it does, try to remove the capacitor.
Variable displacement management is one more way to modify the amount of air flowing into the compressor. By managing the sum of air, the management can hold off the use of added compressors till much more required air is offered. In addition to this, the device can also keep track of the strength employed in the compressor. This manage approach can result in substantial vitality savings. You can even preserve on the quantity of electricity by employing variable displacement control. It is crucial for productive compressed air methods.
Variable velocity push
A VFD, or variable frequency drive, is a type of electric powered motor that adjusts its speed to match the demand from customers for air. It is an successful way to reduce power fees and enhance program trustworthiness. In truth, reports have proven that a twenty% reduction in motor pace can conserve up to 50% of energy. In addition, a VFD can check further variables this sort of as compressor oil strain and motor temperature. By getting rid of manual checks, a VFD will increase the functionality of the software and reduce functioning expenses.
In addition to minimizing vitality costs, variable-speed drives also enhance productivity. A variable-pace air compressor lowers the danger of program leaks by thirty per cent. It also lowers the threat of program leaks by lowering stress in the system. Due to the fact of these advantages, several governments are promoting this technological innovation in their industries. Several even offer incentives to help businesses upgrade to variable-speed drives. For that reason, the variable-velocity travel can reward a lot of air compressor installations.
1 key gain of a variable-pace drive is its capacity to improve strength use. Variable frequency drives are capable to ramp up and down to match the demand from customers for air. The objective is to improve the force and stream in the system so that the very best “useless band” takes place in between forty per cent and eighty % of entire load. A variable-velocity compressor will also improve energy performance because of its programmability.
A variable-speed air compressor can also be used to handle the amount of air that is compressed by the system. This attribute adjusts the frequency of power provided to the motor based on the demand from customers. If the demand for air is low, the frequency of the motor will reduce to preserve energy. On the other hand, if there is an surplus desire for air, the variable-pace compressor will increase its velocity. In addition, this sort of air compressor is more productive than its mounted-pace counterpart.
A VFD has several benefits for compressed air programs. First, it will help stabilize the force in the pipe community, thereby minimizing the electricity losses owing to upstream pressure. It also assists minimize the energy usage triggered by fluctuations in upward force. Its advantages are also much-reaching. And as lengthy as the air pressure and air source is appropriately sized, a VFD will assist optimize the effectiveness of compressed air methods.
