Compact piston pumps

Parker Hannifin has expanded its range of high performance P1/PD hydraulic pumps still further with the introduction of 18, 28 and 45cc models. The new piston pumps increase the existing range of 60, 75, 100 and 140cc models, making the P1/PD Series suitable for use in and even wider variety of medium duty mobile (P1) and industrial and marine (PD) applications. Rated for continuous operation at pressures up to 280 bar, the P1/PD pumps incorporate a number of innovative features to improve performance, reliability and efficiency. For example, low flow ripple minimises noise, while SAE and ISO standard mounting flanges and ports, with a choice of end or side inlet and outlets, make installation quick and simple. An range of options extends the overall functionality and use of the piston pumps still further. These include standard pressure limiters, with or without torque control, and load sensing with pressure limiter and/or torque control. There is also the option for pilot operated pressure limiters with a choice of an ISO 4401 interface, mechanical adjustment and vent port, and electrical adjustment. Edited by Constanze Schmitz
