The series ZW self-priming sewage pumps are developed, based on the combination of YiHai’s ZX self-priming pumps and the series QW sewage pumps. So the pump possesses the advantages from the two original products. They are particularly suitable for pumping the industrial garbage such as mining slurry and the municipal sewage. They are easy to install, remove and operate with the stable operating performance. Proper medium: the diameter of the medium is at most 60% of the diameter in the pump in-outlet, the fiber length is at most 5 times of the diameter in the pump in-outlet. PH of the medium: stainless steel corrosion-resistance pump (1-14), cast iron (6-9). The temperature of the medium≤60℃ 1.Flow capacity(Q):5-800m3/h 2.Head:12-80m 3.Power:2.2-55kw 4.rotatory speed:1450/2900rpm
