Pumps

A fuel pump is an important component of a fuel control system. Its function is to receive fuel from systems fuel tank(s) and deliver it at a high pressure to the control system. These pumps are typically mounted directly on the engine gearbox accessory pad and are engine driven. PECS has long been recognized as a leading designer and manufacturer of gas turbine engine fuel and hydraulic pumps supporting aerospace, marine and industrial applications. Our diverse product lineup includes positive displacement, centrifugal, and vane type main engine fuel pumps, as well as engine boost pumps. We apply advanced analytical capabilities and technologies including computational fluid dynamics to our designs and concepts. We employ manufacturing processes and utilize materials of construction, which meet and exceed customers’ demanding requirements.

Hydromechanical Controls

The Hydromechanical Unit (HMU) or fuel control receives fuel from a high-pressure pump and provides an accurately metered fuel supply to the gas turbine engine. These controls can be mounted to the fuel pump, mounted remotely near the fuel pump or integrated into a common pump and control unit housing. Supply of a total package including pumping system, hydromechanical control and electronic control provides the most cost effective, efficiently integrated package to suit an engine application.

Electronic Controls

The Digital Electronic Control Unit (DECU or ECU) is the computational heart of an integrated electronic control system. The control units are small, rugged, computerized modules that incorporate all the necessary circuitry to gather engine, airframe and pilot/crew command data from sensors, process this data with sophisticated algorithms, and drive output devices to control the system. Typical systems handle a wide variety of I/O types, including thermocouples, speed probes, RTDs, LVDTs, resolvers, strain gages, pressure transducers, Hall Effect devices, discrete input/outputs, lamp drivers, various serial interface buses, relays, solenoids, and DC, stepper, and torque motors.
