Overview of diesel self-priming pump

ZCSB series self-priming diesel water pump unit is a new product successfully developed on the basis of repeated research on similar technologies at home and abroad. The pump set integrates self-priming and non-clogging sewage discharge, adopts axial reflux external mixing driven by diesel engine, and has a unique pump body and impeller wheel design, so it is unnecessary to install bottom valve and irrigation water diversion when using. The pump unit can suck and discharge liquid containing large solid particles and long fiber impurities, and can be widely used in urban sewage discharge, flood control engineering, agricultural irrigation and so on. The pump set has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, convenient use and maintenance, integrated or outdoor movable design.

Service conditions: 1) Ambient temperature ≤50℃, medium temperature ≤80℃, and special requirements can reach 200℃. 2) The medium PH is 6-9 for cast iron and 2- 13 for stainless steel.

3) The medium weight shall not exceed 1240kg/m3.

4) The self-priming height shall not exceed 4.5-5.5m, and the length of suction pipe shall be ≤ 10m.

5) The rotating speed is generally 350 rpm-1000 rpm and 1500 rpm.

Self-priming pump (also known as clear water self-priming centrifugal pump) is one of the series products of energy-saving self-priming pump developed by optimizing and improving similar self-priming pumps abroad. The pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life and strong self-priming ability. There is no need to install a bottom valve in the pipeline, just ensure that there is a fixed amount of liquid in the pump body to work. Therefore, the pipeline system is simplified and the working conditions are improved.

1, self-priming pump is suitable for urban environmental protection, construction, fire protection, chemical industry, pharmacy, dye, printing and dyeing, brewing, electric power, electroplating, paper making, industrial and mining washing, equipment cooling, etc.

2. The self-priming pump is equipped with a rocker nozzle, which can also flush water into the air and disperse it into tiny raindrops for spraying. It is a good machine for farms, nurseries, orchards and tea gardens.

3. Self-priming pump is suitable for clean water, seawater, chemical medium liquid with acidity and alkalinity, and general paste slurry (medium viscosity ≤ 100 cpr, solid content can reach below 30%).

4. Self-priming pump can be used with any type and specification of filter press, and it is the most ideal pump to send slurry to filter press. Materials of flow components of ZX self-priming centrifugal pump: cast iron, stainless steel.
