1/2/3/4 GPM Hydraulic Tandem Gear Pump, 3600 psi

Buy hydraulic tandem gear pump from ideal manufacturer. Displacement 1/2/3/4 Max. GPM for selection, working pressure 3000~3600 psi, speed 1800~4300 rpm, clockwise or counterclockwise rotary is available. 2-stage hydraulic gear pump has double pump, the front and rear gear pumps work independently of each other, and any combination of displacements can be customized according to requirements.

Specification

Note: 

1. Please use ATO gear pump with sufficient oil, otherwise there is a risk of burnout!
2. Calculate the actual displacement value according to the formula: Gallon/min=displacement (ml/rev)*rated speed 1800rpm/3785.41L (speed variation range 500rpm-3000rpm).

Features

• Hydraulic tandem gear pump uses high-strength aluminum alloy shell and alloy steel hard gear transmission, which is light in weight and stable in transmission.
• Installation of the hydraulic tandem gear pump is SAE 2-bolt standard flange. Input shaft connection is woodruff key. Connection type of the oil inlet and outlet ports is thread.
• Hydraulic tandem gear pump has an automatic compensation mechanism for axial and radial clearances, which enables the oil pump to maintain high volumetric efficiency and high mechanical efficiency for a long time.
• Hydraulic tandem gear pump uses SP gears, with small fluctuation, high pressure, low noise and stable performance.
• Hydraulic tandem gear pump uses composite material bearings and high-performance sealing elements, has a small starting torque and good tightness, and can work efficiently under harsh working conditions.

Tips: Why does hydraulic tandem gear pump wear out?

The hydraulic tandem gear pump shell wear is mainly due to the wear of the floating shaft sleeve hole. The normal clearance between gear shaft and shaft sleeve is 0.09~0.175mm, and the maximum should not exceed 0.20mm. When the gear is working, under the action of pressure oil, the tip of gear is close to the hydraulic pump housing, which wears the low pressure cavity part of pump body. The other type of wear is the wear of the working surface in the housing in a circle. This wear is mainly due to the dirty oil added, so hydraulic oil without impurities must be added.
