Self-priming sewage pump is a kind of product with novel structure developed successfully on the basis of repeated study of similar technology at home and abroad. Self-priming sewage pump integrates self-priming and non-blocked sewage. It adopts axial reflux external mixing type, and through the unique design of pump body and impeller runner, it can be widely used in municipal sewage engineering.
Introduction to self priming sewage pump
Product overview
Self-priming sewage pump set self-priming and non-blocked sewage in one, using axial reflux mixing, and through the pump body, impeller flow channel unique design, can be like the general self-priming clean water pump does not need to install the bottom valve and irrigation water, but also suction discharge containing large particles of solid and long fiber impurities liquid, Can be widely used in municipal sewage engineering, river aquaculture, light industry, papermaking, textile, food, chemical industry, electrical industry, fiber, slurry and mixed suspension chemical medium the most ideal impurity pump. Compared with similar domestic products, self-priming sewage pump has the characteristics of simple structure, good self-priming performance, strong sewage capacity, high efficiency and energy saving, easy to use and maintenance, etc., which is the first in the series of sewage pump products in China. Each technical performance index ranks the domestic leading, reaches the international advanced level, has the broad application market and the development prospect.

Each technical performance index ranks the domestic leading, reaches the international advanced level, has the broad application market and the development prospect.
1 Ambient temperature ≤45 ° C, medium temperature ≤60 ° C.
2 medium PH cast iron pump is 6~9, stainless steel pump is 1~14.
3. The maximum diameter of the particle is 60% of the pump caliber, and the fiber length is 5 times of the caliber.
4. The total weight of impurities in the medium shall not exceed 15% of the total weight of the medium, and the specific gravity of the medium shall not exceed 1240 kg/cubic meter.
Self-priming principle
Imbibition refers to the suction tube not filled with liquid (but must have enough fluid in the pump body) under the condition of start the pump, the pump itself can automatically eliminate gas suction tube, and then enter the normal work, must be great enough liquid pump in the first startup, after startup by remaining in the liquid in the pump body to ensure the pump to start again.
