Diesel High Pressure Engine Water Pump
1. Pump Introduction
This series of pump is horizontal multistage single suction centrifugal water pump. This pump is efficient , reliable, and durable with low noise performance, easy maintenance and wide scope of usages. We specialize in manufacturing D, DF, DY and MD series of single-suction multistage centrifugal pumps. The pump is applicable to deliver those fluid without solid, particles or any other suspended stuff, water for instance.While oily and corrosive or solid contained fluid can be pumped by means of material modification, sealing methods, and cooling system adding.
D type : Used for transmission of water free of solid particles and temperature below 80℃ , or similar physical and chemical liquid . Suitable for mining ,mill and city water supply and drainage .
DF type : Used for transmission of corrosive liquid with temperature range for -20℃ ~105 ℃ and non-solid particles material ,sealing methods ,structure of the pump and motor model can be determined by medium , gravity ,density ,working temperature and the suction pressure .
DY type : Used for transmission of non- solid oily liquid and petroleum product with temperature range of -20℃ ~105 ℃ and viscosity less than 120sST .
MD type : Used for transmission of neutral liquid from mining well or other similar liquid .The density and size of particles of the sewage shall be less than 1.5 % and 0.5 mm respectively . The temperature range of the sewage shall be -20℃ ~80 ℃ .
