Product Overview: The pump set is self-priming and non-clogging sewage in one, both as a general water pump without bottom valve, without lead irrigation, can pump containing large solid block, long fiber dirt mine waste impurities, sediment, manure treatment and all sewage works completely reduce labor intensity, and the use of mobile, easy installation, minimal maintenance, stable performance. Features: minimal maintenance, stable performance. Easy to install, easy to use. 3, reduce labor intensity, easy to move, without pressing the foot valve. Main purposes: 1, ambient temperature ≤ 45 ° C, medium temperature ≤ 60 ° C. 2, medium PH value of cast iron pump having 6 to 9, 1 to 14, stainless steel pump. 60% of the diameter of the pump, the maximum diameter of the particles fiber length is five times the diameter, the total weight of the impurities in the medium does not exceed 15% of the total weight of the medium, medium weight does not exceed 1240 kg / m 3. Working conditions: ambient temperature ≤ 45 ° C. Medium temperature ≤ 60 ° C. 3 medium pH value cast iron pump 6 to 9. 4, the stainless steel pump 1 to 14.
