A few years ago we were asked by one of our clients “Do you do High Pressure Flow and Pressure Testing of Hydraulic Systems?”
We said “not yet, but we will investigate and get back to you”.
We called our specialist hydraulics suppliers looking for a Hydraulic flow test kit and we were astounded at the prices of flow test kits.
Starting from Au $4400 and you still needed to supply your own hoses and adaptors to connect to the hydraulic circuit you wanted to test.
So flow testing went on the back burner for a while.
Eventually with more and more clients requesting flow testing services we borrowed a flow tester from one of our trusted advisers, Charlie Gray.
Charlie had built his own from bits and pieces laying around his hydraulics workshop and had then mounted it all into an empty Bosch drill case.
The seed was planted and we then took Charlie’s Idea a few steps further and designed and assembled our own Mono and bi-directional flow test kit with the following capabilities.
Measure Oil Flows up to 120 litres per minute or (32 gallons/Min).
Induce Pressures up to 350 Bar (5150 PSI)
Measure Oil Tempetatures up to 110 Degrees Celsius.
The latest upgrade has been to take the basic Single Direction to Oil Flow design and make it Bi Directional Oil Flow Design.
This upgrade takes all errors out of the connection and testing process as well as being able to test Bi Directional Pumps, closed loop systems as well as Motor and cylinder circuits without having to disconnect and reconnect hydraulic hoses.
This upgrade is awesome value for money at $530 and is well worth it for the additional flexibility and versatility it provides.
Your affordable flow test kit will be Supplied with two 1.5 meter long 3/4″ High Pressure Hoses and a selection of 28 adaptors, this allows the user of this kit to virtually connect to any BSP, JIC or SAE Flanged equipment.
We have sold this Flow Test Kit (see picture below) all over Australia.
Our Price as you see it Under AU $2000 inclusive of GST.

More Information and descriptions of Hydraulic Flow Testing.
A flow test kit is the quickest and least invasive way to quickly check for internal leakage of a suspected component in a hydraulic circuit be it a valve, motor or pump.
A flow test kit can also be used to ascertain if the engine or motor powering the hydraulic system is in good condition and or even capable of powering the hydraulic systems requirements.
Hydraulic pumps, directional control valves, relief valves and cylinders in a hydraulic circuit can be individually checked for internal leakage.
Principle of operation,
The flow test kit is added into the hydraulic circuit and is connected as close as possible before or after the suspected component.
Using a relatively easy process of recorded measurements, logic and simple elimination each component can be individually tested and results compared to the performance of the rest of the hydraulic circuit.
The process described below is used for testing a hydraulic pump.
The flow test kit is installed as close as possible to the pump’s pressure port.
The pump is started and allowed to free flow without load. Flow, and temperature are recorded at free flow.
The flow control valve is then slowly closed to induce a resistance to flow and any changes to flow, pressure and temperature are recorded (usually at 500 PSI intervals) this test is usually carried out up to the pump’s maximum manufacturers recommended pressure.
An alternative to the flow test kit is a High-Quality German made 600 Bar (8820 PSI) rated Digital Pressure Test Kit From STAUFF Germany.
