We have delivered over 100,000 pumps of all types (gear, centrifugal and vane) logging a combined service of more than 523 million commercial hours and 352 million military operating hours. Typical aerospace installations include; commercial & military helicopters, regional and large commercial jets and military fighter aircraft. Industrial applications support both industrial gas turbines and microturbines used in power generation and other applications, while marine uses support shipboard power for military and commercial ships.
The following is a brief summary of the types and uses of pumps produced by PECS.

GEAR PUMPS: High pressure (excess of 1500 psid) Main Fuel Pumps for the aerospace, marine, and industrial applications where highly proven and long life are desired. Examples include the MFP-200 Main Fuel Pump on the General Electric CF6-6 & -50 engines powering DC-10 and 747 aircraft, GE LM2500 marine engine used on Navy ships and the MFP-297 powering the GE CF34-3 engine on the Canadair RJ. Over 4300 MFP-200’s have been delivered to date for all applications logging an impressive 100 million aerospace and 40 million marine operating hours. This has been accomplished at an industry leading 27,000 mean time between removal hours.

CENTRIFUGAL PUMPS: Low-pressure conventional boost pumps are used integral with our Main Fuel Pumps and Controls or stand-alone for charging of the downstream positive displacement pump and/or where demanding inlet requirements are required. PECS has also designed and qualified high pressure centrifugal pumps for high performance military applications. An example is our EFP-630 Engine Fuel Pump, a combined main and afterburner fuel pump system that delivers both gas generator and afterburner fuel flow for the General Electric F414-GE-400 engine used on the U.S. Navy F/A–18E/F fighter. Today the EFP-630 is the only unitized centrifugal main engine and afterburner fuel pump on a production aircraft.

VANE PUMPS: PECS has also designed fixed and variable displacement pumps for main fuel pump applications. Our latest technology step forward is the Variable Displacement Vane Pumps (VDVP) which provide variable flow in a simple, robust and inexpensive package. Temperature rise as a result of fuel recirculation is a major problem experienced in typical positive displacement main engine fuel pumps. The VDVP can eliminate this issue by varying pump output to match the required flow of the engine. Engine designers can thus reduce the size, weight and complexity of the heat exchanger systems.

PECS has since logged over 11,000 hours of cumulative development, design assurance and successful engine testing. A brief summary of these efforts includes successful engine demonstration tests of the VDP-1 on the Honeywell TFE731 and Pratt & Whitney PW300, the VDP-3 /2 on both the Rolls Royce Trent 700 & GE90 and IPC-10 on Pratt 545 turbine engines. Additionally, the IPC-20 is in development and qualification for the Williams International WTS124 engine. We are continuing to develop state of the art VDVP technology today for tomorrow’s applications including the Joint Strike Fighter.

LOLA PUMPS: Our advanced technology Liquid-Or-Light-end-Air “LOLA” boost pumps represent a significant step forward in boost pump technology. It was developed for adverse inlet conditions and has the capability to ingest large vapor bubbles and recondense it into liquid fuel. Its ability to pump air enables LOLA to reprime itself should an interruption of the fuel supply or fuel line occurs. LOLA can also act as a typical boost pump to charge a positive displacement main pump and it has demonstrated the ability to support depressed inlet conditions, which would starve other boost pumps. An example is the EMC-91 LOLA boost pump integral with the EMC-91 on the LHTEC T801 engine powering the U.S. Army’s RAH-66 Comanche.
