The PP2.5/P1-9/1/3BM1/H0/L0 is a hydraulic unit produced by Bosch Rexroth within the Rexroth Power Packs series. It supplies pressurized fluid for automated actuators and small machine tools. The gear pump with a displacement of 0.10 in³/rev converts mechanical energy into a flow that peaks at 0.8 GPM (3.02 L/min), so cylinder speeds stay moderate and controllable. At 1750 rpm, the electric motor drives the pump to achieve the rated flow without cavitation. Motor output is 1 hp, matching the hydraulic load while avoiding excessive current draw. System limits are set to 1800 psi (125 bar), allowing reliable force delivery without overstressing hoses or seals. The manifold provides one D03 station so a single directional valve can be mounted directly, and its SAE-8 port simplifies connection to standard hoses. These features combine to deliver compact pressure generation for stand-alone jigs and fixtures.
Thermal and environmental protection for the drive is handled by a totally enclosed fan-cooled enclosure, so airborne debris does not reach the windings during shop operation. The motor uses a 143TC frame to guarantee alignment with common C-face pump mounts, and it accepts a three-phase 60 Hz supply for consistent torque. Dual-voltage windings permit operation on either 230 or 460 V, giving flexibility in mixed-voltage plants. The reservoir holds 2.5 gal (9.5 L) of fluid, providing enough volume to limit temperature rise and prevent aeration, while an −8 SAE drain port simplifies oil changes. Return flow passes through a 20 µm absolute filter that captures fine particles before the oil reenters the tank, extending component life. Together these elements form a balanced package that supports continuous duty cycles in automated hydraulic circuits.
