Naipu Double Entry Fire-fighting Centrifugal Water Pump



Double entry centrifugal agriculture pump

1. Double entry Centrifugal Pump agriculture pump are single stage, double suction pumps of the axially split type.

2.The Double entry centrifugal pump agriculture pump casing is axially split with the suction and discharge branches located in the lower half.

3. The Double entry centrifugal pump agriculture pump is to allow the complete pump rotor with bearings to be removed for maintenance without disturbing the main pipe work and valves.

Cast Iron Pumps, High Flow Water Pump, Split Casing Pump

Double suction centrifugal pump usage:

1. The range of the Double entry centrifugal pump agriculture pump is suitable for pumping clean or slightly polluted, chemically neutral of aggressive liquids.

2. Double entry centrifugal pump agriculture pump are for water treatment and supply, used In irrigation and drainage system, used In power stations, heating systems and district heating plants.

3. Double entry centrifugal pump agriculture pump are used In the paper and pulp industries, used as marine ballast and cooling water pumps, used In sea water desalination plants, used as pipeline pumps and pressure boosters.

4. Double entry centrifugal pump agriculture pump are used In process engineering and offshore duties.

Double entry agriculture pump structure:

1. Double suction high volume water pump is horizontal split pump and single stage double suction impeller.

2. The suction pipe and discharge pipe are connected with bottom half pump body by casting.

3. You need not to disassemble pipe and motor when you are checking the rotor part of the pump.

Water Pump

Transmission of Double entry centrifugal pump agriculture pump:

Shaft seal of Double entry centrifugal pump agriculture pump:


Double suction water pump is soft packing seal. There is replaceable shaft sleeve at shaft seal place.

Bearing and Balance device of Double entry centrifugal pump agriculture pump: Bearin(rolling bearing or sliding bearing) is installed at both ends of the pump shaft. Axial force is balanced by double suction impeller and spare axial force is balanced by rolling bearing. Grease lubricate the rolling bearing and thin oil lubricate the sliding bearing.
