Hydraulic single gear pump for sale. Available displacement 3/5/13/14 Max. GPM, maximum pressure 3600 psi, speed 500~3500 rpm, optional clockwise or counterclockwise rotary. The small hydraulic gear pump has applications in automobile, hardware, industrial machinery, textile, commercial machinery, chemical equipment, environmental protection, military industry, national defense, etc.

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 single gear pump uses high-strength aluminum alloy shell and alloy steel hard gear transmission, which is light in weight and stable in transmission.
• Hydraulic single gear pump is suitable for SAE standard flange installation. The input shaft connection is woodruff key. Connection type of the oil inlet and outlet ports is thread.
• Hydraulic single 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 single gear pump uses SP gears, with small fluctuation, high pressure, low noise and stable performance.
• DU composite material bearings and high-performance sealing elements, small starting torque, good sealing performance, and strong anti-fouling ability, so that hydraulic single gear pump can work efficiently under harsh working conditions.

Tips: Why does the hydraulic single gear pump have internal leakage?

Hydraulic single gear pump internal parts wear and tear will cause internal leakage. Among them, the large leakage area between the floating shaft sleeve and the gear end surface is the main part that cause internal leakage. This part of leakage accounts for about 50% to 70% of the total internal leakage. For the hydraulic single gear pump with internal leakage, its volumetric efficiency drops, and the output power is much lower than the input power. All of its losses are converted into heat, which will cause the hydraulic single gear pump to overheat. If the bonding plane is pressed tightly, a small amount of movement of the floating shaft sleeve during work will cause abrasion. As a result, the oil cylinder will rise slowly or cannot be lifted. Such floating shaft sleeves must be replaced or repaired.
