Multistage Centrifugal Water pressure Pump with diesel engine 
1)-Specifications
1. Horizontal and compact structure
2. Cartridge mech. Seal structure
3. Wet parts are stainless steel
4. Lower noise, less vibration

High-efficiency, energy-saving, wide performance range, operating safety&steady, low noise, long life and convinent installation.
DF/DM/DW type multi-stage centrifugal pump;

2)-General introduction:
This serial pump is multi-stage section centrifugal pump, the excellent hydraulic models are high-efficiency, energy-saving, and have wide performance range, operating safety&steady, low noise, long life and installing&repairing is very convenient etc. It can deliver heat water, oil, corrosive or wearalbe medium by changing the material, seal or adding cooling system.
Type DM pump can deliver the neuter mineral water which solid particles percent <1.5%(solid Dia, <0.5mm) and other similar sewage, the temperature of the liquid is <80° C. It is suitable for steel works, mines, cities projects etc.
Type DF pump can deliver the corrosive liquid without solid particle, which temperature is from -20° C-150° C
Type DY pump deliver oil or oil products without solid grain, viscosity <120ct, range of temperature is from -20 ° C to 150 ° C
Inlet pressure of pumps is less than 0.6Mpa
3)-CONSTRUCTION
Type DF/DM/DW is consist of stator, rotator, bearing, shaft seal:
1. Stator: The main parts are suction casing, stage casing, discharge casing and diffuser. They are screw up by poles, to become a working house. The suction direction of type D pump is horizontal, the discharge direction is upward; The discharge and suction direction of type DG pump are both upwards, and the suction direction is horizontal usually, also they can be made upward according to user's requirement.
2. Rotor: It is consist of sharft, impellers, balance dic and shaft sleeve etc. Shaft supplied power to impellers; The axial force is balanced by balance disc; The sleeve mounted on shaft to protect shaft.
3. Bearing parts: It is consist of bearing body, bearing and bearing cover etc. The bearing of type 85-67, 155-67, 600-60 pump is sliding bearing, lubricated by diluted oil, the other pump bearing is rolling bearing, lubricated by grease.
4. Shaft seal: It is usually adopted soft packing seal, consist of sealing house on suction casing, packing, blocking water ring, the sealing hose have some pressure water, to cool, lubricate and seal pump. Type D pump pressure water is come from pump itself, type DG, DM, DF, DY pump pressure water is come from pump itself or outer water. Type DG, DF, DM, DY pump usually adopt mechanical seal.
Drive: The pump is driven directly by motor through elastic coumpling, the rotation of pump is clockwise looking from motor to pump.
4)-DESCRIPTION OF SELECTING PUMP
1. Pump performation see sheet of performance data. The data in sheet is test performance at 1 atmosphere&nomal temperature&clean water, when the medium is high viscosity, the performance should be transormed.
2. The pump type, data, and gravity, temperature, viscosity, corrosive feature tec, must be stated in the order.
3. If you requried data is different from the data in sheet of performance Data, our company also can design according to your requirement.
