What Is A Medium Open Pump?

May 09, 2026

Single stage double suction centrifugal pump is a horizontal center open pump used for conveying clean water or other liquids with physical and chemical properties similar to water. According to user needs, the pump structure and material can be changed to transport multi mud sand water or various corrosive liquids. This series of pumps is suitable for factories, mines, urban water supply and drainage, power stations, farmland irrigation and drainage, and various water conservancy projects.
1. The allowable working pressure is 2.5Mpa; The pump inlet pressure+pump head is ≤ 2.5Mpa. According to the high pressure borne by the pump casing, the material of the pump body and pump cover is gray mouth casting (1.6Mpa).
2. Medium: Clear water with a temperature ≤ 105 ℃ or other liquids with physical and chemical properties similar to clear water (solid particles 80mg/L).

 

1. Sealed rolling bearings lubricated with grease are easy to maintain and have a long operating time.
2. Equipped with a constant oil level oil cup, it can also be lubricated with thin oil.
3. High quality bearings are selected for smooth operation, low bath noise, and long service life. Compact structure and good stability. This type of pump has a split structure with the pump casing, and both the inlet and outlet are located on the pump body. During maintenance, only the pump cover needs to be lifted out, and the rotor components can be removed for maintenance without disassembling the pipeline, which is very convenient. The electric motor (driver) can be installed on the left or right end as needed, making it convenient for on-site installation. Structurally shortening the axial dimensions of rotor components results in better shaft rigidity and more stable and reliable operation. There is a pump body character sealing ring, and the impeller sealing ring is an optional component. The sealing ring can be replaced after wear, reducing operation and maintenance costs.
