Gear Pump VS centrifugal Pump Working Principle

Booster pump is conveying fluid or make fluid machinery, mainly used for conveying water, oil, pulp, the sour lye, emulsion, hangs emulsion and mixture gas and liquid metal, etc., is a mining, chemical and metallurgical industries common conveyor equipment. Finishing is Gear Pump VS Centrifugal Pump Working Principle, hope to everyone in the selection and use of pump has the certain help.

Gear pump working principle

Gear separate from each other, forming a low pressure, liquid is inhaled, and sent other side along the shell wall. On other side. Two gears close together, creating a high pressure to expel the liquid.

Advantages: simple and compact structure, small size, light weight, good manufacturability, cheap price, strong self suction, not sensitive to oil pollution, large speed range, impact load, easy maintenance, reliable work. If transfer corrosive acid and alkali liquid, or food grade liquid, you can choose stainless steel gear pump, you can rest assured to use.

Centrifugal pump Working principle

When the centrifugal pump works, the liquid fills the pump shell and impeller rotates at high speed. Liquid produces high speed under action of centrifugal force. High speed liquid passes through the gradually expanding pump shell channel, and the dynamic pressure head changes into static pressure head.

Centrifugal pump Performance characteristics:

High efficiency and energy saving: pump has high efficiency hydraulic line, high efficiency.

Convenient installation and maintenance: vertical pipe structure, pump inlet and outlet can be installed in any position and any direction of pipeline like a valve. Installation and maintenance is very convenient.

Stable operation, safe and reliable: motor shaft and pump shaft are directly connected coaxial, high concentricity, stable operation, safe and reliable.

Stainless steel bushing: the mechanical seal position of the shaft is relatively easy to be corroded. Once direct pump shaft is corroded, it is easy to cause mechanical seal failure. Stainless steel sleeve is used to avoid rust, improve the life of shaft and reduce the cost of operation and maintenance.

Bearing: lower shaft extension end bearing of motor equipped with pump adopts closed bearing, which is free maintenance motor bearing in normal use.

Mechanical seal: base parts of mechanical seal generally choose rubber bellow structure. Traditional mechanical seal shaft seal from o-ring line seal to rubber two surface seal, in the medium of water improve sealing effect.

Classification: can be divided into stainless steel centrifugal pump, chemical centrifugal pump, centrifugal hot oil pump, insulation centrifugal pump and so on.
