Test bench for diagnostics of single- and double-circuit pumps with mechanical drive. The test bench measures flow and pressure parameters under different speed. Besides, it detects such faults as leak, roar, body wear out, reducing valve sticking. It is an equipment of general service, used for work with power steering pumps of all types. The key features of the bench are easy operation and reliability.

The efficiency of the unit under test is determined by comparing the pressure and flow of liquid that it creates when working on the bench, with the indices of the same serviceable pump. During the inspection, the absence or presence of a leak is visually assessed.
Checking the serviceability of the pump HPS on the stand allows you to make sure that the unit that is diagnosed will work properly when it is installed on the car.
The step of changing the revolutions of the cartridge at the stand is set by the appropriate regulator and is 50 rpm. This regulator also changes the direction of rotation of the cartridge. In addition, the touch-sensitive display has the function of setting fixed indicators of the cartridge's rotation (500, 1000, 1500 rpm).
It is necessary to install the pump on the stand, i.e. to clamp the drive pulley in the chuck and fix the unit by means of an appropriate fastening; start the stand, set the speed of the drive, determine the pressure and flow rate of the fluid developed by the pump; load the test unit with a suitable crane, release the tap and again determine the required indicators. Differences in the flow rates before and after the load will indicate the hanging of the pressure relief valve.
Checking the pump with two circuits on the bench is similar to the one described above, but only connect the hoses (high and low pressure) to each circuit. The pressure on the manometer and the flow rate of the liquid through the flowmeter are determined on each circuit.
