8SP Deep Well Submersible Pump Introduction

Pump body is well directly connecting with diving asynchronous motor, assembles into submersible pumps.

The diameter of the pump is 10 inch.

The power of this pump ranges from 11kw-100kw.Usually used for medium and large projects.We can recommend different

configurations according to customer needs, such as size, head, flow, etc., to meet different needs of customers.

The runners of our impellers are carefully designed and adjusted to adapt to motors of different powers.The number of impellers and the mismatch between the flow channel and the motor will cause many problemsIf the electronic power is too large, the cost performance of the water pump is too low.If the power of the water pump is too small, then the electronics will burn up after long-term high-load operation.

8SP submersible pump

8SP stainless steel multi-stage deep well submersible pump is a new type of machine for extracting groundwater.

It is widely used in industrial and mining enterprises for water supply, irrigation of farmland, and groundwater for self-use.

Since the pump main body is made of stainless steel, it is corrosion-resistant, wear-resistant, energy-saving and efficient.

Fully reliable, and because of its compact size, small size and light weight, it is very easy to maintain,

Transportation, installation and use, combined with automatic energy-saving and efficient control box, with over temperature, short circuit,

Overload and undervoltage overload protection, safe and reliable.
