FAQ

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: How can I get trained on CNBM products?

A: Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

Q: Are your pumps cheaper than those of your competitors?

A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

Q:Sewage treatment plant design how many pumps should be selected, head how to calculate the maximum design flow is 833M3/h
Pump selection to consider the flow, lift, diameter and power, but also with reference to the actual workload, the design quantity is 1666, how much can actually achieve? Head to refer to pipe length, height difference, elbow number, such as flow in more than 800 of the pump, lift at 35 meters, can generally meet about 200 of the pipeline work needs.
Q:Why should the water inlet of water pump be fitted with reducer?
Increasing the pipe diameter can reduce the resistance loss along the path and reduce the suction vacuum of the pump! Before the inlet of the pump is a big diameter, when you reach the suction port, and the pump inlet diameter to be consistent, so the use of reducer joints!
Q:Water pump maximum flow and standard flow?
According to my estimate, a pump has the best working point, then this standard flow I think should refer to the best working point, that is to say you want to flow 480l/h, choose this pump is best
Q:Why does the pump decay when connected in parallel?
Pump parallel mainly solves the problem of insufficient flow. After parallel, the flow is two and the sum of the pumps. When the flow rate increases, the pressure loss of the pipeline will increase, so the water pump flow in parallel will not be the sum of the two pump flow, but less than the sum of the flow rate. The solution is to increase the diameter of the water supply pipe, reduce the angle bend and shorten the distance.........
Q:TDH what units are present in the pump parameters?
In the pump parameters, TDH is the head of President (Ying Chi).The formula is as follows:TDH (Ying Chi) = total head (Ying Chi) = (- water pressure readings + drainage pressure gauge (drainage dynamic head - water head + (drainage pressure gauge - water pressure elevation correction table elevation correction)
Q:What is the reason for the overload of the water pump indicator?
If the power is normal:1, the pump is indeed overloaded (at work to see how much the ammeter indicates).2 、 the motor is out of order.3 、 the thermal relay is not adjusted properly or aging.
Q:What does water flow mean?
The amount of water delivered by the pump during the unit time, that is, the flow of the pump. Generally, there are three kinds of time units, namely, seconds, minutes and hours. In our country, the unit of flow adopts the international metric units, liters, milliliters, cubic, thousand cubic meters, etc., and different units are used according to different usage environments.
Q:Is the motor with a pump a squirrel cage induction motor?
Not necessarily, mussaurus main motor and conventional motor rotor winding is the difference of mussaurus, can be in series with other equipment, to achieve more functionality!
Q:Diving pump voltage
This is the reason why the line is too long and the power consumption is too large
Q:What does the pump lift mean?
The pump head is the height or length of the distance from the pump to the outlet
