6618 German technology multistage stainless steel submersible water pump

Product Overview

Description

Introduction:

We called this kind pf pumps Ritz submersible pump because of the ritz pump producing technology we have introduced from Germany.

 

Type Description:

6618×8

66series code number

18: pump type

8: eight-stage impellers 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, emergrency rescues, urban water supply, enterprise and government instution 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 hotwater lifting. Different specifications and types provided for different wells.

 

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 equisitive 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%
