1. Production Introduction 2. Application 4. FAQ 1. Are CNBM pumps available in DIY stores? Yes, currently, we’re available for DIY stores all over the world. 2. Where do I have to send pumps for service? You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China. 3. Are your pumps acid-proofed? To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid. 4. With regarding the submersible pumps, we can just get a pump head? It would be acceptable to arrange the pump head alone. All connections are conforming with the international standard. But it is also very necessary to have a confirmation before the delivery, because there are some models which is special. 5. Do you have smaller solar pump? Yes, we have. Except the solar submersible pump, we also have some surface solar pump, the voltage about it is 12V or 24V. The materials about them are plastic. 6. Can you customize the pump when we needed? This is acceptable. But we have to charge some fees in advance, because we need to make the new moulds for it sometimes.

- Q: 5 floor water pressure is too low, what kind of water pump is better?
- Pipe blockage, leaks, or throttling devices are not opened. This can be tested on a pipe with a pressure gauge;Water pump is equipped with power source, power or speed does not match, check the pump and power end nameplate, power end of the pump power is generally 1.1.5 times;
- Q: The water tank of the fish tank does not air out and only has the water outlet
- The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.
- Q: What does the pump mortar do?
- Concrete pump before the need to transport water and pump pump material, dredge pipeline. In accordance with the technical specification for concrete pumping construction (JGJ/T10 - 1995), pumping concrete, pump mortar generally use cement slurry
- Q: What does "anti pump" mean in pump operation?
- The working process of the main oil cylinder pushing back and forth against the pump when the S valve (C valve or valve or gate valve skirt) reverse swing, so the piston suction concrete cylinder is in the ash conveying pipe is exactly opposite is the pump suction pump (hopper is concrete and push into the hopper, the desizing)
- Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
- When the vacuum pressure is called vaporization pressure, cavitation is more than the surplus energy of vaporization pressure at the unit weight of the liquid in the pump suction port of the unit, with mark. The absorption process is to NPSH delta H: pump suction fluid allows the vacuum pump installation height is the unit of rice.
- Q: Advantages and disadvantages of centrifugal pumps?
- Centrifugal pump; advantages and disadvantages:(1) advantages:The structure of the pump is simple and compact, and the centrifugal pump has small area, light weight, little material consumption and high cost for the foundation. Therefore, the cost of manufacturing and installation is less.For high speed operation, the 2 pole or 4 pole motor can be directly connected. The drive structure is simple and easy to install.
- Q: Difference between pump and compressor
- A pump is a machine that transports liquids or pumps liquids. It transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, and also can transport liquid, gas mixture and liquid containing suspended solid. Pump can usually be divided into three types of displacement pumps, power pumps and other types of pumps according to the principle of operation. In addition to classification according to the working principle, it can be classified and named according to other methods. For example, according to the driving method can be divided into the electric pump and the turbine pump; according to the structure can be divided into single-stage pump and multistage pump; use can be divided into the boiler feed pump and the metering pump; according to the nature of transmission fluid can be divided into water pump, oil pump and mud pump etc.. In accordance with the non axial structure, can be divided into linear pumps and traditional pumps.
- Q: Why is the flow of the pump too small will occur cavitation phenomenon?
- Throttling regulation is to change the opening of the valve to change the flow of the pump, that is to say, to change the characteristic curve of the pipeline. The commonly used to regulate the flow of exports, because the entrance throttle makes reduce the inlet pressure caused by cavitation danger.
- Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you
- The valve opening pump is aimed at the centrifugal pump.From the power curve of the centrifugal pump, the power of the centrifugal pump increases with the increase of the flow rate; the flow curve of the centrifugal pump shows that the flow rate of the centrifugal pump decreases with the increase of the head.
- Q: What are the differences between the sewage pump and the clean water pump?
- Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.
