Type Description

6620×4

66 series number

20: pump type

4: four-stage impeller series connection

Application

66 series pump is single suction multistage submersible pump that can applied to farm irrigation, garden sprinkling, fountain landscape, rainwater recycling system, mining drainage, emergency rescues, urban water supply, enterprise and government intuition water lifting. It can be used in horizontal position(while its service life will be inferior to that of vertical using). This product has some advantages of low noise, high efficiency and energy saving.

Its suitable for enterprises and public institutions such as bath center, district heat supply, power generation, underground hot water lifting. Different specifications and types provided for different wells.

Structure description

66 series submersible pump applies the space conductance guide valve structure, and it composes of pump, motor, controller. The pump contains working part, pipe (including check valve ).

1) working part

For pumps with strong axial force, we equipped with balance hole in order to relieve the pressure, then the motor could bear the rest.

We are strict about the concentricity and axial movement. With exquisite accessories and accurate axial locating dimension, the machine has a long service life and can be operated smoothly and reliably.

2) Pipe

The pipe contains check valve, discharge pipe and pump frame. Outlet of check valve is connected with the discharge pipe to prevent the water regorging when the power is cut off. Water flows out from check valve through discharge pipe, pump frame, ground gate valve and pipes to the destination. The pump frame is fastened on the concrete plinth, supporting the whole weight of the pump.

Medium Range

1        Clean water, cold water, rainwater, gushing water of mining, drinking water,etc.

2        Water temperature range: +5--+105℃

3        Solid content (mass ratio): ≤0.01%

4        PH: 6.5-8.5

5        H₂S content: ≤1.5mg/L
