Cast Iron Double-Sided Entrance Pump for Agricultural Irrigation

Brief introduction:

ZSS type pump is a new generation of high performance single-stage double suction centrifugal split pumps.They are mainly used in delivering liquids of the water plant,air conditioner circulation water,heating pipe network system,building water supply,irrigation and drainage of pump stations,power plants,industrial water supply system,fire protection,ships industry and mine.

Parameters:

Features:

1.Using excellent hydraulic model, the efficiency of the pump is 2-3% higher than that of the same type, and the operating cost of the pump is reduced.  

2.Unique high temperature design, the pump adopts intermediate support, thickened pump body, sealed cooling, bearing thin oil lubrication, so that the pump can be applied to the high 200oC operating conditions, especially suitable for heating pipe network requirements  .

3.The pump body part can be installed vertically or horizontally according to different working conditions, and the seal can be mechanical seal or packing seal.  

4.The NPSHr is reduced by 1-3 m.

5.It is unnecessary to adjust mechanical seals,so it is very easy and simple to replace them.

6.It is rapid and simple to assemble and dismount the rotor parts due to using elastic prestress assembling.

Structure:

1.The distance between the two ends of the pump is short, the pump runs stably, the vibration noise is small, and the speed can be increased properly, so that the pump can adapt to a wider range.  

2.The inlet and outlet are in the same straight line, so that the pipeline layout is simple, convenient and beautiful.  

3.The same rotor can run in reverse, reducing the risk of water hammer damage to the pump.

4.It is unnecessary to make adjustment to any clearance when assembling.
