Introduction of ESP End Suction Single Stage centrifugal Pump

Without any crane equipment, no matter whether the motor power big or small, one person can replace the motor bearings and mechanical seals within 20 minutes.

General description of ESP End Suction Single Stage centrifugal Pump
ESP,Series New Hi-Tech Centrifugal Pumps are designed to resolve the present single stage centrifugal pumps high failure rate in the market, such as leakage of Mechanical seals, noisy of motor bearings, Bearings over temperature when running …etc, if the mechanical seals or bearings need to be replaced on site, usually it is limited by space and crane equipments, especial for the big motor unit, it is no way to remove the motor and have to lift by hands depending on many manpower , or have to build tripod, it is very inconvenient and easy to damage the workers and equipment if failure.

FAQ of ESP End Suction Single Stage centrifugal Pump

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. Can your pumps mount Eff.1 motors

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

Q:Fire pump room is required to set up water pump control room?
What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control
Q:25KW what is the lift of the pump?
2 floor, the following formula is not accurate, the margin of safety is too large.N=Q (L/s), *H (m), /102/ (0.6~0.85), /0.85As follows: for reference only: (pump flow * pump lift) / (367* pump efficiency) * pump motor power safety margin (constant general take 1.1-1.2) = pump power.Unit: flow M3/H, head MNow you know the power of the pump, but you do not know the efficiency of the pump and flow, so the pump head can not be calculated.Can the normal operation of pump flow velocity detection using ultrasonic detection equipment, combined with the calculation of pump diameter of the flow and shaft power testing equipment can use foreign advanced measure pump, electric motor with related input parameters to calculate the pump efficiency. Then use the formula above to calculate the pump head.The simple way is to ask the designer directly about the design parameters.
Q:1 water pump frequency converter constant pressure water supply wiring diagram
Light can not be seen in this picture, but also need to see the definition of the terminal on the practical manual, generally speaking, the three terminals are connected to +10V, public and analog signals / multi-function terminals.
Q:What is the difference between self-priming and non self suction?
The self-priming condition of the centrifugal pump is that a small water tank is attached to the pump body. Don't use water every time you start. No suction, no water tank. And the use of volumetric Self-priming pumps, such as car cleaning, high-pressure pumps are in this category.
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:What is the definition of the pump in the capacity of the pump?
I don't know very well about your work there;General pump is a one, or two with a preparation work; pump and standby pump capacity is big, the maintenance of pumps is provided here, said in the overhaul, overhaul maintenance enabled pump, pump capacity can be greatly reduced, as long as the pump 1/4, thus reducing the volume of the standby pump the.
Q:After the pump has a control box, but also the distribution box?
This look at the specific situation, the water pump circuit is divided into power, power and control signal two parts,They can be placed in a larger cabinet, which is convenient for future inspection and repair.There is power and signal is separated from the general distribution box and put some air contactors, frequency converter etc.,There are some buttons, lights, etc. in the control box.
Q:What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
The little air hose is had to pump in pump operation, to play the role of oxygen, generally want to let the oxygen hose head above the water, or to go into the air, and lose the function of oxygen, if the tank is large enough, every day to open the filter pump. Use hose plus oxygen does not matter.
Q:Diving pump voltage
Small amount of water, it should be the lift can not meet the requirements, change the submersible pump is the best solution. With 380 volts, it is very likely to burn out the pump motor.
Q:What's the meaning of a single-stage pump?
In fact, the simplest difference between multi-stage pumps and single-stage pumps is that more than one impeller and one impeller can be summarized.The so-called single-stage pump is the pump inside only one impeller pump, so that we can be referred to as a single-stage pump, which is characterized by the head is not high, but the flow rate could reach thousands of square per hour, the typical model is the ISG type single-stage centrifugal pump.The pump is a pump body which contains a plurality of impeller pumps, pump is characteristic of such a large flow and high lift, traffic can be thousands of square kilometers to the head, but the cost is not low, customers should be chosen according to the actual parameters.
