43 -- Diesel Injection Pump Test Stand

The contract calls for the supply of a Diesel Injection Pump Test Stand, specifically one unit manufactured by Bacharach or an equivalent supplier. The model specified is 67-7685 Technician 7.5 or equal and includes an accessory kit suitable for testing the Roosa Master GF Pump Model 60-0000 or its equivalent. Key features required include a continuously variable speed range of 70 to 3500 RPM, a single block accumulator that can be mounted on either side of the stand, and a return fuel flowmeter capable of measuring flow between 140 and 1400 cc/min. Additionally, the test stand must have a dual mode digital tachometer and stroke counter, at least eight acrylic pyramidal measuring graduates, and heavy-duty, oil-resistant push button switches. The technical specifications emphasize performance and durability, with a minimum 7.5 HP drive motor controlled by a variable frequency controller featuring braking and field programmability with self-diagnostics. Speed control is managed by a rotary dial capable of at least six speeds or equivalent, coupled with a backlash-free flexible coupling and laminated disc design. The flywheel has a moment of inertia of 1145 lb-in-squared, with acceleration and deceleration factory set to 200 RPM per second or better. The reservoir capacity is 13 gallons with a 10-micron submerged filter, electric submersible heaters for temperature control (accurate to +/-1 degree Celsius), and cooling via tap water through copper finned tubing. The system includes a transfer pump rated at a minimum of 1/3 HP with a flow rate of 150 gallons per hour and instrumentation such as a fuel inlet temperature gauge covering 40 to 140 degrees Fahrenheit. The accessory kit must provide all necessary hardware, fittings, hoses, and mounting brackets to enable testing of Roosa Master Injection Pumps used on Buda Diesel Engines. The contract is a total small business set-aside under the Department of Defense, specifically issued by Malmstrom Air Force Base.
