A4VG Series Pump Works
The pump A4VG is an axial-piston swashplate design, having pistons arranged in a circular pattern about a drive shaft. They contact with and press against a slanting plate known as swashplate. This makes the pistons to move back and forth in their barrels due to the inclined position of rotation of drive shaft. As they do so, hydraulic fluid is forced out through outlet port while being drawn in from inlet port by this sucking movement.
Stroke length for each piston can be changed by altering the angle of inclination on either side of maximum displacement; hence, it changes output volume per revolution thereby controlling flow rate too. When swash plate gets to its highest point where it can still go further before coming back down again towards zero degrees; then we say that such condition corresponds to 100% value regarding both displacement and flow rate adjustments.
Stepless variation between these two points (0% and 100%) is possible thanks to A4VG mechanism which ensures smoothness plus accuracy during flow control.

Rexroth A4VG Plunger Pump - Installation Instructions
Install Instructions
The hydraulic fluid must be filled and the air bled from the axial piston unit during commissioning and operation. This also applies after long shutdowns since the axial-piston unit can drain hydraulic lines, especially in those “drive shaft upwards” installations which shall remain protected against dry running to avert hazardous situations.
Leakage oil drainage
All housing area leakages must be guided back into the tank through the highest drain port (T1, T2). For combination pumps, each pump’s leakage should be drained individually. If several units share a common drain line, ensure that no housing pressure exceeds allowable maximum values for any given unit; besides, it is advisable to size such shared drains correctly so that at no point under any working condition including cold starts does maximum permitted housing pressure of all connected units get surpassed by this line. When this cannot be achieved then separate drains need to be installed.
Noise Control
Elastic elements should be used when fixing pipes together with tanks so as to dampen noise levels. Avoid installing any above-tank connection
Suction and Return Lines
At every moment of its operation suction as well return lines should run below minimum oil level in reservoir tank. The suction head hS max depends on total pressure loss but should not exceed 800 mm 0bar . During cold start period suction pressure at port S must never fall beyond 05 bar abs while under normal circumstances it can’t go lower than 08 bar abs.
Tank Design
It is necessary to provide sufficient spacing between inlet/outlet ports while designing these tanks hence use a partition (baffle) between them if possible because doing this will enhance air separation efficiency by giving more time for entrained air bubbles contained within liquid being pumped out through an appropriate point where they can be easily released from system thus reducing chances of their re-entry also hot oils returning directly into suctions shall cause cavitations which are highly undesired. The partition shall supply bubble-free, calm, and cooled hydraulic fluid through suction port.
