Horizontal Multistage Pump D155-30x9 With Electric Motor And Control Cabinet

Horizontal multistage pump D155-30x9 with electric motor and control cabinet

General description

The 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 wearable medium by changing the material,seal or adding cooling system.

Type D pump can deliver water without solid particle or the liquid which the chemical and physical feature are similar with water and temperature is≤80℃, it is suitable for delivering mater in mine andurban water project etc.

Type DG pump can deliver clean water without solid particle or the liquid which the chemical and physical feature are similar with water, and temperature is≤105℃, it is suitable for delivering boiler feed water or heat water.

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℃.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℃~150℃.

Type DY pump deliver oil or oil products without solid grain.viscosity≤120ct, range of temperature is from -20℃ to 150℃.

lnlet pressure of pumps is less than 0.6MPa.

Description of pump type

D155-30x9

D----Multi-stage horizontal centrifugal pump

Construction

Type D DG DM DF DY pump is consist of stator, rotor, bearing, shaft seal:

1. Stator: The main parts are suction casing, stage casing, dischargecasing 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 upward; the discharge direction of type DM,DF,DY pump are upward, and the suction direction is horizontal usually, alsothey can be made upward according to user's requirement.

2. Rotor: lt is consist of shaft, impellers, balance disc and shaft sleeve etc. Shaft supplied power to impeller; The axial force is balanced by balance disc; The sleeve mounted on shaft to protect shaft.

3. Bearing parts: lt is consist of bearing body,bearing and bearingcover 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: lt is usually adopted soft packing seal, consist ofsealing house on suction casing, packing, blocking water ring, thesealing house have some pressure water, to cool,lubricate and sealpump. Type D pump pressure water 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 coupling.The rotation of pump is clockwise looking from motor to pump.
