ZW type self-priming pump is based on the relevant technical data at home and abroad by absorption, digestion, improved after the development of energy-saving pump products. The pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, convenient maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install the bottom valve in the pipeline, only need to keep the pump body to store quantitative liquid before work, so the pipeline system is simplified, to improve the working conditions.
Main uses:
1. Equipped with rocker nozzle, the water can be rushed into the air and scattered into small raindrops for spray. It is a good machine for farms, nurseries, orchards and tea gardens.
2.Suitable for clean water, sea water and chemical medium liquid with acid, alkalinity and with general paste paste (medium viscosity ≤100 centiper, solid content can be up to 30% below).
3. It can be used with any type and specification of filter press. It is the ideal pump to send the slurry to the filter press for pressure filtration.
Product features:
1. Strong sewage discharge capacity: special impeller blocking design ensures high efficiency and no blockage of the pump.
2.High efficiency and energy saving: the use of excellent hydraulic model, the efficiency is 3 ~ 5% higher than the general self-priming pump.
3. Self-priming performance is good: the self-priming height is 1 meters higher than the general self-priming pump, and the self-priming time is shorter.
