Pump X 20/53 - chemical pump. The pump X 20/53 compares favorably with imported analogs with a price that is not inferior in quality. Reliable, easy to operate.
When selecting a pump, determine the required parameters - the material of the flow path, the type of seal, the power of the electric motor.
The productivity of the pump X 20/53 is 20 cubic meters.
Head 50 m.w.st.
Chemical pumps X 20/53 are used for pumping aggressive, chemically active, toxic, flammable, various kinds of neutral media. The pumped medium may contain hazardous substances of different hazard classes, whose vapors, together with air, can form explosive mixtures under certain conditions. These include liquefied gases. Therefore, the need to work in explosive or fire hazardous conditions must be specified when ordering!
The density of the pumped medium by the pump X 20/53 must be no more than 1850 kg / m³, the content of solid inclusions in an amount of no more than 0.1% by volume with a particle size of no more than 0.2 mm.
