Axial piston pumps

At a time when energy costs are rising, hydraulic drive efficiency is the decisive competitive advantage. HYDAC axial piston pumps of the PPV series convert mechanical energy into hydraulic power with minimal losses. What makes them special is the fact that, as variable displacement pumps, they adjust their swivel angle – and thus the flow rate – precisely to match the actuators’ actual demand. When no movement is required, the pump returns to ‘zero displacement’. This saves significant amounts of energy, reduces heat build-up in the system and extends the service life of all components.

Precision in detail – swash plate design

Our pumps are based on the proven swash plate principle, which enables continuously adjustable control of the delivery volume:

High pressure resistance: designed to handle standard nominal pressures up to 350 bar and peak loads up to 400 bar.
Wide range of controller types: whether you need a pressure controller (01/P), a remotely adjustable pressure controller (07/PR), a load-sensing controller (14/LS), an electrically remotely adjustable pressure controller (E07), an electro-proportional flow volume controller (ED) or a power controller (09/TC), we have the right technology to meet your control needs.
Low noise emission: thanks to optimised control panels and a vibration-damping housing design, our pumps remain surprisingly quiet even at high pressure.

Engineering for advanced systems

Designers appreciate the high power density of the HYDAC PPV series. The compact dimensions make installation easier in the tight engine compartments of construction machines or compact industrial units. Our axial piston pumps are validated for use with a wide range of media, from standard mineral oil to non-flammable fluids. When combined with HYDAC’s variable-speed drives, even greater energy savings can be achieved. When you choose HYDAC, you’re selecting a long-lasting, high-performance component that significantly reduces your total cost of ownership (TCO).
