Bosch Rexroth is expanding its A3V pump platform for industrial hydraulic applications with the new A3V2Q090 model. The variable displacement pump, which can deliver flow rates of up to 286 litres per minute, aims to reduce energy consumption in cyclical applications. According to the company, the A3V platform can deliver energy savings of up to 70 per cent compared with fixed-speed systems.

Bosch Rexroth is adding the A3V2Q090 model, with a nominal displacement of 90 cm³, to the A3V pump family it developed for medium-pressure hydraulic systems. The new product complements the existing 45 cm³ A3V2Q045 model and is intended to meet higher flow requirements, particularly in presses, plastic injection moulding machines and industrial systems operating in cycles.

Lower energy consumption at high speed

Thanks to its high rotational speeds, the A3V2Q series can deliver the same flow with lower motor torque. According to Bosch Rexroth’s data, the pump reduces the motor torque requirement by 30 per cent, allowing smaller servo motors to be used. By adjusting the flow to demand, the torque requirement can be reduced by a further 30 per cent in many cyclical applications. This makes it possible to size the servo motor and frequency converter smaller.

The servo-motor-driven variable displacement pump can adjust its rotational speed and swashplate angle to the operating conditions. The system can also operate in pump and motor modes, enabling energy recovery. The recovered electrical energy can be used in the DC link or fed back into the grid.

Efficiency of more than 91 per cent

Bosch Rexroth states that the A3V2Q series achieves an efficiency of more than 91 per cent in its optimum operating range. This represents an increase of up to five percentage points compared with previous medium-pressure variable displacement pumps.

According to an example given by the company, a CO₂ emissions saving of 50 tonnes can be achieved on a medium-sized press. Actual savings vary depending on the operating conditions of the application.

The new A3V2Q090 model is scheduled for market launch in the first half of 2027.
