Self priming centrifugal pump with vacuum suction device
The self priming pump need to be filled with water. The vacuum suction device can help the self priming pump to enhance the suction and can start and stop suction automatically. When the inlet pipeline or self priming pump is into low vacuum degree, the vacuum suction device starts automatically. When inlet pipeline or self priming pump is into high vacuum degree, vacuum suction device stops automatically. At the process vacuum suction device enhances the suction height of self priming pump up 9meters and then self priming pump sucks the fluids and discharges them. Mechanical seal is for dry grinding mechanical seal and self priming pump can work without fluids.(idle)
ZSW Series self priming centrifugal pump with vacuum suction device can be used to transfer various wastewater or waste liquids with solid particle, fiber etc impurity. The vacuum suction device can enhance the suction height of self priming pump up 9 meters. Larger discharging flow rate and better self priming performance. ZSW Series self priming centrifugal pump with vacuum suction device can be made of cast iron or stainless steel material according to the different fluids.
Flow range:80-2200m3/h
Head:10-80m
