Overview: HW series pumps are horizontal, single-stage, single-suction after open mixed flow pump volute. With a reasonable structure, reliable, easy maintenance, and high efficiency, small size, light weight advantages. 2. Scope: HW series pump for conveying water, the concentration does not exceed 3% of the pulp or PH = 3 ~ 10, the fiber length is less than 80mm of solution, and the physical and chemical properties similar to water, other liquids, transmission fluid temperature is not should be higher than 50 ℃. Widely used in agricultural irrigation, industrial wastewater and urban drainage. HW especially among low lift flow pump head low flow, low energy consumption, high efficiency, especially for low-lift pumping station construction and renovation areas. 3. Performance range: Flow 180 ~ 900m3 / h Head 3 ~ 12.5m inlet diameter 150 ~ 300mm supporting power 4 ~ 30kw 4, Material: paper pulp type sewage water pump HT200HT250 type PH value of the solution according to the impeller HT200 be different cast iron ball head shaft 45 # 45 # pump cover HT200HT250 packing seal packing or mechanical seal packing or mechanical seal
