Self-priming pump is not required before the start of irrigation (after the installation of the first start still need irrigation), after a short period of operation, by the role of self-priming pump itself, that is, the water can be sucked up, put into normal work.
Self-priming pump, using a reinforced polypropylene (CFR-PP) injection molding. Self-priming pump high mechanical strength, corrosion resistance.
Self-priming pump structure has a unique science, the pump chamber is equipped with suction chamber, liquid chamber, back to the liquid check valve, gas-tuck separation room, back to the hole. Self-priming pumps need only be primed before the first booting, and do not have to be primed repeatedly.
Self-priming pump in the suction medium, the fluid can be intermittent intermittent, off fluid within 12 minutes to continue suction liquid, mechanical seal without additional cooling water, easy to operate, safe and leak-proof, self-priming pump is replaced The best product for submerged pumps.
Self-priming pump material: non-toxic, non-polluting, resistant to general acid-base salts, self-priming pump temperature -14 ℃ ~ 80 ℃.
