Product Overview ZW Self-priming sewage pump is the company's designers ZX model based on self-priming centrifugal pump and QW structure and properties Sewage pumps, the advantages of similar products at home and abroad to learn and absorb many customers requirements and the comments, developed from one set of self-absorption and sewage, both as a general self-priming pump water as need bottom valve, without irrigation water, but can pump large solid particles having a diameter of 60% and export caliber fiber length is 1.5 times the diameter of the impeller dirt, sediment, mine waste impurities, excreta disposal and all sewage works and colloidal liquid completely reduce labor intensity, but also to use, easy to move, installation, minimal maintenance, performance stable. Applications: 1, ambient temperature ≤45 ℃, medium temperature ≤120 ℃. 2, cast iron pump medium PH value of 6 to 9, a stainless steel pump 1 to 14. 3, the maximum particle diameter by 60% of the pump diameter, fiber length of 5 times the diameter. 4, the total weight of impurities in the medium does not exceed 15% of the total weight of the medium, medium weight does not exceed 1240kg / m3. Model significance For example: 65ZW20-25-4 ZW- split self-priming non-clogging sewage pump 65- caliber (MM) 20- Flow (m3 / h) 25- Head (m) 4- with motor power (kw)
