Product details

Double suction self-priming pump product introduction:

Double suction self-priming pump is designed by our company according to market demand
And a new energy-saving double suction self-priming pump product with a completely new structure has been developed.
This pump fills the historical gap of this type both internationally and domestically, completely solving the problem of single suction self-priming
The problems of high axial tension, long self-priming time, and low efficiency of the pump,
Has high suction range, short self-priming time, high efficiency, and energy-saving effect
The advantages include significant fruit, stable operation, and long duration.

Double suction self-priming pump is suitable for conveying clean water or mild sewage, with an efficiency ratio of
High sewage type and good self-priming performance. Self suction collection
Integrated with unobstructed discharge, using axial reflux external mixing, and
Through the unique design of the pump body and impeller flow channel, there is no need for installation
Bottom valve and irrigation water can also suction and discharge solids and fibers containing particles
Impurities in liquids can be widely used as ideal impurity pumps for chemical media such as municipal sewage engineering, lotus pond aquaculture, light industry, papermaking, food, chemical, electrical, fiber, pulp, and mixed suspension.

Direct coupled double suction self-priming pumpScope of use
1. The ambient temperature is ≤ 50 ℃, and the medium temperature is ≤ 80 ℃. Special requirements can reach up to 200 ℃.
2. The pH value of the medium is 6-9 for cast iron and 2-13 for stainless steel.
3. The medium density used in the sewage type double suction self-priming pump shall not exceed 1240kg/m3, and the lift of the sewage type pump of the same model shall be 10% lower than that of the clean water type pump
4. The self-priming height cannot exceed the specified value of 5-7 meters, and the length of the suction pipe is ≤ 10m.
5. The sewage type double suction self-priming pump has a capacity to suspend particles with a diameter of about 20% of the pump diameter and a fiber length of 5 times the pump diameter.
