ZGD Screw self-priming pump

Product overview:

ZGD screw self-priming pump mainly by the motor, water pump, seal three parts. The electric motor is an asynchronous motor the electric pump adopts the unique structure of centrifugal impeller-diameter guide leaf-injection tube, the principle is that the pressure is first created by the nozzle vacuum, and then the low-water liquid is sucked into the pump inlet bypump superchargingexclusion withself-absorption function.

Product use:

ZGD-type self-absorbing screw pump is widely used in low-water areas of well water, household water, because of high head, large flow, but also particularly suitable for water tower water supply,high-pressure irrigation ofhigh-rise residential, vegetable shed water supply, fountains and other occasions.

Conditions of use:

The electric pump should work continuously under the following conditions of use;

1.the transport medium temperature does not exceed 40 degrees C;

2.the MEDIA PH value between 6.5-8.5;

3.solid impurities volume ratio does not exceed 0.1%,particle size is not greater than 0.2 mm;

4.the power supply frequency is 50Hz, the voltage is single-phase AC 220V, three-phase Ad380V. Voltage fluctuations range from 0.9-1.1 times the rating;

5.when the temperature is below 0 degrees C, should do of antifreeze work, when not using need open the bottom of the pump body waterproof screws, drain the pump body water. protecting from freezing the pump body;

Note: Automatic before use. It is important to ensure that the tube is not leaking.
