Product Overview Traditional industrial pumps are often too long or bulky to be installed directly onto the PTO of a truck transmission due to interference with the drive shaft or truck frame. The Rexroth AA10VNO28 solves this problem with its optimized, short-profile swashplate design. It delivers variable flow proportional to the engine speed and displacement setting, converting mechanical PTO power into flexible hydraulic energy.
Why Choose the Rexroth AA10VNO Series?
-
Ultra-Compact Footprint: Specifically designed to avoid collision with chassis components. The shortened housing allows for direct flanging onto standard commercial vehicle PTOs.
-
Energy Savings (Variable Flow): Unlike traditional fixed gear pumps that constantly pump oil (creating heat and wasting truck fuel), the AA10VNO with DR control destrokes to zero flow once the maximum system pressure is reached. It only pumps exactly what the implement needs.
-
High Speed Capability: Designed to operate safely at the high rotational speeds typical of truck PTOs without cavitation.
-
Viton Seals (V): Equipped with FKM (Viton) seals, allowing it to withstand higher operating temperatures and providing compatibility with a broader range of hydraulic fluids.
Common Applications:
-
Commercial Trucks: Refuse trucks (garbage compactors), hook loaders, and skip loaders.
-
Municipal Vehicles: Street sweepers, snowplows, and salt spreaders.
-
Truck-Mounted Equipment: Truck-mounted cranes (Knuckle boom cranes), aerial work platforms (cherry pickers).
