FAQ

Q: Are CNBM pumps available in DIY stores?

A: Yes, currently, we’re available for DIY stores all over the world.

Q: Where do I have to send pumps for service?

A: You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.

Q: Are your pumps acid-proofed?

A: 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.

Q: Can your pumps mount Eff.1 motors

A: Currently, only on request though this will shortly be a CNBM standard.

Q: Are your pumps protected against dry running?

A: No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

Q:Water pump belongs to power equipment or mechanical equipment?
It's mechanical equipment!
Q:Does the IP55 indicate the lift on the water pump nameplate?
IP55 refers to the level of protection
Q:Water pumps are always pumping water, what's the matter?
Cause analysis of water pump without waterThere is air in the inlet pipe and pump body(1) before the water pump is started, the water is not filled enough. Sometimes it seems that the water has been discharged from the vent hole, but the pump shaft is not rotated. The air is completely discharged, resulting in a small amount of air remaining in the inlet pipe or pump body.(2) in contact with the water pump inlet of the horizontal application of reverse flow direction, fell more than 0.5% slope, connect one end of the highest import pumps, do not completely level. If the upward tilt, the intake pipe will retain air, reducing the water pipes and pumps in the vacuum, water absorption.(3) pump packing has been used for long-term wear or packing pressed too loose, discharge gap caused by the large amounts of water from filling with the shaft sleeve, the external air gap into the pump from the inside, affected the water.(4) because of the long latent water and the corrosion of the pipe wall, the water inlet of the water inlet is constantly dropping. When the holes appear above the water, the air enters the water inlet pipe from the hole.(5) there is a crack at the bend of the inlet pipe, and there is a small gap between the inlet pipe and the water pump, which may cause the air to enter the inlet pipe.
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
May not。1, the system is designed according to 2+1, 1 standby, only redundant backup of important equipment, not included in the running load.2, higher power distribution only provides 2 (maximum operating conditions) equipment rated operating power capacity (slightly margin, but limited).3, a single 160KW motor rated current is about 300A, 185 cable can only be used for the 1 pumps (with 2 units, and has overload) 630A circuit breaker is the frame level, if the current setting value is 630, it should be the main power switch (single pump with 400A circuit breaker, setting a value of 315 or 350A).4, if the 630A as the main switch to provide 2 pump power, has been close to full load (third pumps can not be added).5, water pipeline system, although not what caused the problem, but the water flow rate, flow rate of 2 pump operation should be in the ideal range, adding third pumps (the premise is to ensure the power supply) will make the water flow velocity is too large, in non ideal conditions.Conclusion: this method is inadvisable. If necessary, modify the original system, change to 3+1 mode, and change the line and circuit.
Q:Electrical design into!!! Is the water pump lamp waterproof?
No specific requirements are available
Q:Should the no-load power of the pump be equal to the rated power?
Manufacturers in order to make money, the nameplate marked "1200W", in fact, the maximum power of the motor, only 750W.
Q:The water burst how to repair?
This is used by welding and making AB calls
Q:After the pump has a control box, but also the distribution box?
1, after the pump has the control box, do not need the distribution box.2. The control box is not the same as the distribution box.Wiring principle is as follows: from the distribution box power supply into the control box, L1, L2, L3 (usually so); from the control box to connect U, V, W to the water pump.
Q:Why is water pumping cool water is normal, but when pumping hot water pressure and flow are very small?
You look at what you pump that is, there are manuals to see how much the media can not exceed the degree,
Q:Pump power ratio design is small, the problem is big?
Lift and flow to meet the requirements of power, in fact little difference, different manufacturers and brands in the same common effect of different power phenomenon, design principle is on the one hand, the hysteresis loss mechanical loss processing technology is one of the reasons of the differences. Power, after all, does not increase, and does not have a major impact on other lines.
