Self Priming pumps are self priming centrifugal pumps , the dual seals of the pump consists of mechnical seals and sketleton seals, the pump is compact in constructure, fine in performance , convenient in maintain and saving about 50% water compare to furrow irrigation.

1. The trans medium's temperature to pump shouldn't be higher than 40degree;
2. Trans medium's pH VALUE: 6~8;
3. The grain diameter of the solids in the water is no bigger than 0.2mm
4. Single-phase pump
5. Self-priming pump, with high aborption and high lift-head
6. Brass impeller
7. Adopt skeleton-type oil sealing or mechanical sealing.
8. Based on general self-priming pump, automatic function is added and the pump can be applied to hot water.
