Product Name: Stainless Steel Clean Water Pump

Product Introduction

stainless steelclean water pumpIt has the advantages of high efficiency, energy saving, low noise, and reliable performance. Compliant with the standard JB/T53058-1993 of the Ministry of Machinery of China, it is used for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for industries such as petroleum, chemical, metallurgical, power, papermaking, food and pharmaceuticals, and synthetic fibers.

Product Features

1. The shaft seal adopts mechanical seal or a combination of mechanical seals, using high-quality hard alloy sealing rings to enhance the wear resistance of the seal and effectively extend the service life of the pump.
2. Import and export at a 180 degree angle to meet different connection scenarios.
3. The stainless steel water pump has a compact structure, small volume, and beautiful appearance. Its structure determines that the installation area is small. If a protective cover is added, it can be used outdoors.
4. Easy installation and maintenance, no need to disassemble the piping system. The inlet and outlet of the pump have the same diameter, simplifying the connection of the pipeline.
5. The impeller is directly installed on the motor shaft to ensure the concentricity of the pump, thereby enhancing the operational stability of the pump and extending its service life.
6. Series or parallel operation of pumps can be adopted according to the needs of flow rate and head.
