PPEV3-011-12C — Electric Motor Driven Variable Delivery Hydraulic Packaged Pump Assembly Repair & Overhaul

Component Overview

An electric motor driven variable delivery hydraulic packaged pump assembly is a self-contained hydraulic power unit combining an electric drive motor with a variable-displacement piston pump, integrated within a single package with controls and porting. It supplies pressurized fluid to aircraft hydraulic systems, automatically varying output flow to match demand while maintaining regulated pressure, often serving as an auxiliary or standby power source. As a hydraulic component it converts electrical energy into controlled fluid power. Overhaul is driven by piston and cylinder-block wear, swashplate and bearing degradation, compensator valve sticking, internal leakage and efficiency loss, shaft seal failure, motor brush or winding deterioration, and contamination damage, all of which reduce delivered flow, pressure stability, and reliability of the assembly.

Aircraft Application

Part number PPEV3-011-12C (Electric Motor Driven Variable Delivery Hydraulic Packaged Pump Assembly) is installed on the Beech King Air 300/Beech 1900. QTC supports operators and MROs servicing this platform with certified repair and overhaul.
