1. Production Introduction:
WZB self-priming pump is divided into single phase and three-phase asynchronous types with built-in protection device. The pump is divided into centrifugal impeller and worm casing structures with self-priming function. Single-face mechanic sealing is mounted between pump and motor."0" shaped oil-proof rubber seating ring is used at each stationary port as static sealing.
2. Application:
This series pump is a new type of ideal economical pump, widely used in pumping water, increasing water pressure, garden irrigation, water supply for vegetable green houses, industrial mining enterprises and aquatic breeding fields etc.
3. Work Conditions:
The pump can work properly and continuously under following operational conditions:
1.Medium is not corrosive.Sand contents should be max.0.10% by volume and granular size should be max.0.20mm.
2.Medium temperature shouldn’t be over 40°C and PH should be 6.5-8.5.
3.Power frequency should be 50Hz,single phase voltage 220V, three-phase voltage 380V,and voltage fluctuation should be 0.9-1.1 times than the rated.
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.
- Q: What are the reasons for sealing damage of centrifugal pumps?
- Two, cavitation. Cavitation (mainly from a thermal centrifugal pump).Because the medium is hot water, the water temperature is too high to produce steam, the gas in the pipeline enters the pump cavity height, and the part of the gas can not be discharged, thus causing water shortage to run, the machine seal dry grinding is invalid, and the cavitation erosion device is not available.Process: replace the machine seal.
- Q: What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you
- Variable pump variable refers to the flow can be changed to distinguish from the constant flow of quantitative pumps.
- Q: What's the meaning of the pump head in the water pump, please advise, thank you
- The pump head of the centrifugal pump refers to the shell that contains the impeller and impeller, and also includes the shaft part that drives the impeller. It can be used as the part of the motor and shaft coupling and the base.
- Q: What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
- Pump flow: the volume of liquid discharged per unit time.(3) volume efficiency of pump: the ratio of actual output flow of pump to theoretical flow rate.
- Q: Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?
- With the pressure does not matter, because the pressure is small, it is necessary to boost the pump, the water pressure with the pipe flow and the size of the booster pump related
- Q: What is the difference between the ground pump and the pump in the commercial concrete?
- Move back and forth; pour concrete into a certain area. After the filling is finished, the whole pump truck can be moved to another position quickly
- Q: Why is the sewage pump device coupler?
- The automatic coupling device but the installation of GAK type submersible sewage pump, need lifting, people may not need to unscrew the screw water, the water pump can directly improve, after repairing down along the guide rail can realize sealing pump and pipeline, water pump and normal operation. Small sewage pump can be installed freely, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.
- Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you
- When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.
- Q: What is the cause of the damage of pump bearings?
- In high-speed equipment, the most likely damage to bearings is high temperature.
- Q: What is the difference between an air pump and a water pump?
- The air pump (Q. B ng air pump), namely "air pump", a device for removing air or add air from the enclosed space from a closed space. The air pump is mainly divided into an electric air pump and a manual air pump. Electric air pump. An electric pump powered by electricity; produces air pressure by constantly compressing the air through electricity. Mainly used in pneumatic rubber, car inflatable, etc..
