Hydraulic Tester – 54Gpm
The 380500047 all mechanical hydraulic tester provides the solution for servicing and commissioning hydraulic circuits on agricultural and other mobile machinery. The kit comprises of a direct acting flow indicator with built in thermometer, a loading valve and a pressure gauge all built into a strong steel case with a removable lid. The kit allows reverse flow but does not indicate flow rate in the reverse direction. The unit is self-contained and requires no electrical power. The dials are clear and easy to read. The test kit can be connected into either the pressure or return lines. The loading valve and pressure gauge allow a progressive build-up of system pressure to simulate working conditions. 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.
- NO BATTERIES REQUIRED
Features and Specifications
Measures Flow, Pressure, Temperature
Measures flow in one direction only, but ALLOWS FREE REVERSE FLOW
A safety disc protects system and operator against accidental over-pressure in both flow directions. Protection against over pressure is provided by two internal safety discs which relieve at 6400 psi, 440 bar without external spillage. The safety discs are housed in a cartridge and are easily replaceable. Lower safety disc pressures are available.
- No external spillage of fluid.
- Flow is measured by a tapered metering piston moving within a fixed, sharp edged orifice designed to minimize the effects of changes in temperature and viscosity. The piston movement is proportional to the change in flow rate. In reverse the piston moves back to allow the flow to return at low pressure.
- Flow Accuracy: ± 4%
Solid high tensile flow block houses a metering piston and guide, the piston moves against a calibrated spring housed in a guide. The piston can move in both directions allowing flow from either the inlet and outlet port as required. The piston is magnetically coupled to a rotary pointer to provide a direct reading of flow from the inlet direction on a clear 2 1/2” diameter flow scale calibrated in gpm and lpm. Both the flow and the temperature scales are shielded behind impact resistant windows.
• Pressure Accuracy: ± 1.6% of full scale Glycerin filled 2 1/2” dual calibrated (psi/bar) pressure gauge 0 – 6000 psi gives a continuous reading of system pressure.
Temperature Range up to 230°F (110°C) For continuous use at fluid temperatures up to 180°F (80°C), for intermittent use for less than 10 minutes, at up to 230°F (110°C). Indicated in °C and °F by a thermometer built into the flow block to measure temperature changes in the fluid passage.
• Accuracy: ± 5°F or 2.5°C
Loading Valve and Pressure Gauge
The loading valve is connected directly to the flow block and a 6000 psi, 420 bar pressure gauge is mounted in the inlet section of the loading valve. The valve is easy to operate and, combined with the pressure gauge, allows sensitive and progressive control of system pressure throughout the working range.
The complete unit is built into a rugged steel case which provides protection against accidental damage during transportation or testing. The detachable lid provides access to the instrument dials and the safety disc cartridge is easily accessed to replace safety discs.
