Nomenclature:
D360-40x10(P)

D means multi-stage clean water multistage centrifugal pump
360 means the design point of flow capacity is 360 m3/h
40 means the design point of single-stage head is 40 
10 means the stage is 10 or the number of impellers is 10
P means self balancing pump.

New Structure:

Electric Motor Symmetrical Impeller Multistage Water Pumps have a symmetrical arrangement of rotor impellers into two opposite groups that make the positive and negative axial thrust offset each other during the operation. So it doesn't need a set of wearing parts balancing system as the traditional structure of multistage pump.

High Efficiency:

 The operation efficiency of the pump is 2% -3% higher than the traditional multistage pump.

High Stability:

For clarified water with guarantee for 2 years.

Reliability of Mechanical Seal:

No axial pulsation of the rotor and rotor parts during the pump starts and stops. This feature overcomes the problem of the unreliability of the Mechanical seal.

Convenient Maintenance:

Modular design,replacing the packing seal and bearing no need to disassemble the pipeline.

Low maintenance rate:

Reduce the vulnerable parts, extend the product life, thus reduce maintenance times and cost
