Hydraulic gear pump PGZ

hydraulic pistonfor industrial applicationslow-noise

Frame size 4, 5 Size 20 … 140 Maximum operating pressure 15 bar Maximum displacement 136.3 cm³ Features Low-pressure pump with fixed displacement Very low operating noise Suitable for broad viscosity and speed ranges Excellent suction characteristics Can be combined with axial piston pumps, internal gear pumps and vane pumps Use for: Cooling, filter or lubricant circuits with low pressures in industrial or mobile applications, e.g. plastics processing machines, machine tools, presses and wind turbines. Set-up Hydraulic pumps of type PGZ type are gerotor pumps with constant displacement. They basically comprise of: Flange housing (1), shaft (2), the displacer element inner rotor (3) and gerotor (4) as well as driving disk (5) and cover (6). Suction and displacement procedure Via the driving disk, the shaft drives the inner rotor in the indicated direction of rotation. The inner rotor cogs with the gerotor to turn it.
