Multi-stage water pump product features:

1. Advanced hydraulic model: high efficiency and wide range of performance.

2, installation and maintenance is convenient: pipeline installation, import and export can be installed in any position and any direction of the valve like valve, multi-stage clean water pump installation and maintenance is very convenient.

3, the multi-stage clean water pump appearance is beautiful: the use of high quality stainless steel coat, beautiful appearance.

4, less operation and maintenance costs: the use of high quality mechanical seals, wear resistance, no leakage, long service life, low failure rate, multi-stage clean water pump has less operation and maintenance costs.

5, unique components, noise reduction: unique hydraulic components design, good overflow performance, maximum flow noise reduction.

6, vertical structure, small area. Stainless steel chemical pump

The multi-stage clean water pump is connected to the motor and the pump. The fulcrum bearing of the motor rotor is also a pump bearing, which is rigid power transmission to make the pump impeller rotate working pressure reducing valve. Between the water pump impeller shell and multistage eddy current only 0.10-0.22 mm gap, sand debris stuck dead impeller, a motor rotor can not rotate and failure. From the analysis of the repair of the multistage water pump, the damage of the motor rate is more than 80% because of the death of the impeller card. When the power switch when the motor does not turn, immediately turn off the power, the motor work is to produce a rotating magnetic field in inductor, the motor will not be damaged in a short time. The rear cover of the motor can be removed with a screwdriver, and the blade of the rotating fan is straight to the back cover and then electrified.

Before the use of multi-stage clean water pump, attention should be paid to voltage coincidence and electric safety. Because the clean water pump works in wet environment, the leakage protection switch should be installed before the power switch. Do not move the work of multi-stage water pump, water pipe valve vertical 0.4 meters into the water, poor water quality should be set up to prevent debris filter effects of inhalation of water pump in multistage pump operation.

The hydraulic structure parameters of the multistage water pump are the best combination to obtain the highest efficiency. For other pumps, this kind of pump with special requirements can not exceed the efficiency of the clean water pump at the same time. The main reason that other pump efficiency is lower than that of clean water pump is that their overflow channels are widened. The value of the decrease in efficiency is mainly related to the extent of the widening. Other pump flow channels are widened to prevent blocking.
