A fuel pump back-pressure test stand can be built with QKL electronic proportional pressure regulator ( I/P converter) components to handle the testing of a variety of fuel pump sizes. QKL combines with a back-pressure regulator is controlling upstream pressure in a fuel pump test. A flow monitor is downstream measuring flow and sending a signal to the controls, which is sending a command signal to the QKL electronic proportional pressure regulator ( I/P converter) to either increase or decrease the pressure in the fuel to meet the specific requirements of the test.
Our proportional pressure regulator is best suited for this application due to its high flow rate, fast response time, and high accuracy. Our regulators are capable of modulating from 2 bar to 65 bar with accuracy of 0.25% FS. (higher pressure range can be customised upon request) QKL electronic pressure regulator can directly replace: Proportion Air ( QB3H, QBS, GX, QBX, QPV, QB2 ), Festo ( VPPM, VPPL, VPPE, VEAA, VEAB, VEMD ), SMC (ITV1000, ITV2000, ITV3000), Clippard (Cordis), and ASCO (Sentronic)
