Pump introduction

IS series pump is horizontal, single stage, single casing centrifugal pump. The pumping liquid is clean water, pure water or other liquid which physical and chemical nature is similar to pure water. The liquid temperature should not be higher than 80 celsius.

ISW

Pump specification

the max flow rate is 400m3/h, 

max discharge head is 125m, 

rotation speed have two types: 2900 and 1450 rotation per minutes.

Suction size: 50-200mm

Outlet size:32-150mm 

Impeller diameter: 125-400mm

NPSHr:2-5m, which determine the suction head of end suction pump.


Pump structure

The pump body and cover are separated from the back of impeller, that is to say back-pull structure.     It is convenient for us to check and repair the pump. 

We don't move pump body, intake pipe, discharge pipe and motor, just disassembly the middle connector of extended coupling to quit rotor units.

Shaft sealing of IS pump is gland packing and mechanical seal.

The drive of IS pump can be electric motor and diesel engine.

Pump application

End suction pump are widely application, usually for agriculture, farm, irrigation, city water supply, water drainage.


Pump installation

it is important to keep the pumps movement and duration, therefore installation guideline must be carefully carried out.

1. Clear up grease and filth on the foundation and then place it on the ground

2. Check the foundation levelness with a leveler

3. Pour cement into the foundation and foot bolt holes

4. After the cement is dried, check if both foundation and foot bolt holes are loose, then properly tighten the foot bolts and recheck the levelness.

5. Clean up the foundation’s support plane, the planes of pump and motor feet, and then mount pump and motor on the foundation

6. Keep a certain space between the clutches, check if the central lines of pump and motor shafts are identical.

7. the pump’s installation height, the pipeline diameter and length, flow rate should comply with the calculation and try to reduce unnecessary loss.

8. Use a bigger diameter pipeline if long distance transportation. The pump lines should have a stand of its own and don’t let the pipeline weight upon the pump.

9. Mount the check valve outside of the gate valve on the drain-out pipeline if necessary.
