Rotary Gear Pumps Manufacturer

Sauer Danfoss (Turolla) Gear Pumps


Gear pumps are rotary pumps that use two meshing cogs to pressure out liquids with both low to high viscosities. Gear pumps are simple, durable and inexpensive pumps which are suitable for pressures under 20 MPa (three,000 psi). These pumps fall under positive displacement, which implies that they pump a gradual quantity of fluid for every cycle. The liquid is then trapped by the gear enamel and forced out to the outlet through the discharge stroke. For lubrication, the gear pump utilises a small quantity of oil that comes from the compelled facet of the gears that flows by the hydrodynamic bearings and expels the identical oil to the a part of the gears with low pressure.


Turolla OCG high efficiency gear pumps are mounted displacement pumps which consist of the pump housing, drive gear, pushed gear, DU bushings, rear cover and front flange, shaft seal and inside/outer seals. For those who fill the gearbox from the highest hole, until you might be VERY LUCKY you will get an air lock in the gearbox, this will be an enormous bubble of air that takes up the area required for the gear oil to fill.

The lube oil provide downstream of the lube oil filter feeds the turning gear pump, which is driven by the identical AC-Motor that drives the jacking oil pump. Oil that is discharged from the pump is guided to the frequent turning gear housing, which consists of an axial movable drive pinion, a coupled radial piston motor and a control Gear pumps block. Piston moves axially towards a spring force within the path of the gear rim on the turbine shaft.
