Our Diesel Water Pump Set,can be choose Deutz/Cummins/Ricardo Diesel Engine Driven Self-Priming Pump Set For Irrigation(Manufacturer)/Water Pump Generator/Hose Pump/Water Pump Set Product introduction: P series self priming non-clog centrifugal sewage pump is a new generation product which develop on the basis of the lastest technology and craftwork. Because of the reliable performance, its life lasts more than 20 years. We take special usage of the sewage pump into consideration on design, so we add a hole to make sure that stronger sewage can be cleaned quickly when pump is jammed. The unique lubrication oil mechanical seal cavity makes the performance more reliable and avoids to damage mechanical seal when it operates without water. To ensure a smooth operation, low noise, long life, all the main components such as imported bearing, to overcome the traditional inherent shortcomings such as low flow rate capacity, difficult to install, difficult maintenance and frequent failure. P series self-priming Pump has the character of strong anti-clogging. In order to avoid towels, bags and so long fiber pollution caused by debris blocking the sewage pump sewage poor. We Design will cut down pollution-pore structure In front of the pump to ensure that the debris can be cleared more quickly. There is a big vortex chamber play important role. It is no need to equip check valve in the inlet and outlet to sewage efficiently when the pump separately completely. Main usage: 1. Municipal Project, Sewage Project, Instruction Project 2. Transportion of the sewage of uptown 3. Sewage transportion in Hospital, hotel and so on 4. Classification of municipal sewage treatment factory and concentrate treatment systems engineering. 5. Transportation of the factory and contaminated water Operation condition: 1. The temperature of medium no more than 80° C, the density of medium is 1.0~1.3*103 Kg/m3, PH is within 5~9, 2. Max diameter of solid should be less than 75 mm, 3. Max suction lift no more than 7 m
