Mechanical Hydraulic Tester – RFIK Series


The RFIK mechanical hydraulic tester offers the perfect solution for troubleshooting and servicing hydraulic systems on agricultural and other mobile machinery. The kit consists of a direct-acting flow indicator with a built-in thermometer, a loading valve, and a pressure gauge all built into a strong steel case with a removable lid for protection.

The volumetric efficiency (internal leakage) of hydraulic pumps will increase with age. Consequently, to prevent unnecessary downtime it is vital to check the efficiency of hydraulic pumps on a routine schedule. An analog flow indicator with an integrated load valve and an analog pressure gauge in one compact unit is perfect for testing hydraulic pumps without removing them from service.

The unit is self-contained and requires no electrical power. The dials are clear and easy to read. Installation is extremely simple, and the test kit can be connected to either the pressure or return lines. The loading valve and pressure gauge allow a progressive buildup of system pressure with the user’s safety in mind.

The test kit provides the service engineer with quick, accurate, and simple performance testing of pumps, motors, valves, steering systems, cylinders, and complete hydraulic circuits.
