DTM Light small single-stage centrifugal electric water pump

This series of pumps are suitable for civil and industrial uses to pump clean water and chemically non-aggressive liquid.

They have a compact size and are extremely reliable, very simple to use and almost maintenance-free.

 

DTM light and small single-slage centrifugal pump is composed of three parts: cClick, water pump and seal. The motor is a single-phaseasynchronous motor, and a singie mechanical seal is used between the pump and the motor It is used for waler supply and drainage of riverwater and well water, breeding, gardens, hotels, canteens and building maintenance.
1. The water supply condition is clean water,and the liquid temperature is less than 40℃;
2.The pH of the medium is between 6.5-8.5;
3.Open impeller design, the solid particle size in the medium is not more than 0.4mm;4. The voltage fluctuation range is 0.9-1.1 times the rated value;
5. The air in the pump must be drained before use,otherwise the water cannot be pumped normally.
