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 form is flat key shaft. Connection type of the oil inlet and outlet ports is threaded.
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: Commonly used calculation formula of hydraulic single gear pump.

Motor power：W = P × q × n/54000 (kW)
P = gear pump working pressure (MPa)
Q = gear pump displacement (GPM)
n = motor speed (rpm)

Gear pump torque: T = P × q/1.7π（N.m）

Motor torque: T = 9550 × W/n.

Oil hose inner diameter matching: oil suction pipe inner diameter d = (0.12～0.18) × q × n
q = gear pump displacement (GPM)
n = motor speed (rpm)

Note: tubing inner diameter d = (0.06～0.09) × q × n

Oil return pipe inner diameter d = (0.09～0.12) × q × n

Flow calculation: flow L = π × d2h/4000t (GPM)

Piston rod diameter d (mm), piston rod stroke h (mm), working time t (s), displacement: q = 60 × L/n (ml/r)
