FAQ  

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: Do you have self-priming pumps?

A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

Q: Is it really necessary to fit a bleed valve for the boxes?

A: It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q:What are the categories of pumps?
As long as you see, you need flow, lift, power
Q:Why should the water inlet of water pump be fitted with reducer?
Is the water in the end sealing (Shaqi) under the condition of satisfying the original design of the pumping pipe flow.Water injection; height of the larger, more sacred,
Q:The role of impeller in water pump
The impeller is driven by electric motor rotation, the middle impeller creates a vacuum to vacuum at the inflow of water will be (on the surface water is continuously sucked into the impeller), then the water through the high-speed rotation of the impeller of the water discharge, play a promoting role in water.
Q:Water pumps are always pumping water, what's the matter?
First check whether the water pump suction gas 2 check the negative pressure of the pump suction is too low 3 check whether the water pump 4 no problem of opening the pump head to check whether the water pump impeller damage
Q:What kind of water pump does the 5.5KW motor have?
Model has: QS-250-40-21, lift 21m, flow 40 square, motor power is 4KW, water pump diameter is 232cmQJ-200-40-26, lift 26m, flow 40 square, motor power is 5.5KW, water pump diameter is 189cmYou can choose the right pump according to your well path.
Q:How do I calculate the power of the pump?
Motor Power (kw) =0.163*Q*H*K/60/EOf which: Q is the flow, unit m^3/hH is the lift, unit ME is the efficiency value of the pumpK is the safety factor, generally 1.1.
Q:Ask the principle of fire truck and pump adapter
Fire engines have their own hoses. I've seen them. They usually have hydrants. They take water from them. If they don't work, they have their own water
Q:What is a 1 inch water pump?
The caliber of the water inlet and outlet pipe is 1 inches of water pump,
Q:What is the relationship between pump power, lift and flow?
When the power is constant, the kinetic energy theorem is known as P=F*V, that is, W=F*S.In the water pump, it is said that the work done by the unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
Q:The role of water replenishing pump in circulating system
There are three ways of constant pressure in water system. 1, the expansion tank constant pressure, this method applies to small and medium water systems, low cost. 2 water pump constant pressure, the role is when the system because the water shortage during the operation, resulting in insufficient pressure, the water supply system can play the role of water pressure. 3 pressure tank fixed pressure, pressure tank fixed pressure at the same time, also need replenishment pump water, the individual feel that the first two kinds of economic reality
