Product Description

Metal parts for 3SP, 4SP, 5SP, 6SP, 8SP and 10SP series of submersible pump such as impeller, diffuser, pump outlet and suction support etc. are made of wearable and anticorrosive stainless steel AISI304 through advanced moulding and punching craft procedures. Rubber bearing is made of wearable rubber with low friction. The connection method between coupler and motor is in compliance with standard of NEMA. Our impeller and diffuser are designed and manufactured according to the requirements of high efficiency, high reliability and long service life.

Feature:

1. All metal materials are 100% SS304, the structure is corrosion resistant, clean and environmental friendly, and will not cause secondary pollution to the water quality.

2. It is equipped with check valve to prevent the impact of backflow water pressure when the electric pump stops. Drain holes can also be set on the check valve seat according to the customer's needs to slowly drain the water in the pipeline to prevent the pipeline from freezing in winter.

3. All stainless steel impeller has obviously higher wear-resistant and longer service life than the ordinary plastic impeller and brass impeller, so that the pump has high efficiency, good stability and long service life.

4. Stainless steel sand net to prevent sand or large particulate matter into the pump body.

5. Special thrust bearing is installed to effectively prevent the damage in the process of starting the water pump and transportation.
