Hydraulic Tester - With Pressure and Flow Capabilities
You must have o-ring face seal (ORFS) adapter fittings
for this tester to use it on the Groundsmaster 455-D.
1. INLET HOSE: Hose connected from the system
circuit to the inlet side of the hydraulic tester.
2. LOAD VALVE: If required, upon turning the valve to
restrict flow, a simulated working load is created in the
circuit.
3. LOW PRESSURE GAUGE: Low range gauge to
provide accurate reading at low pressure, 0 - 1000 PSI.
This gauge has a protector valve which cuts out
when pressure is about to exceed the normal range
for the gauge. The cutout pressure is adjustable.

in the operation circuit, with a gauge rated at 15 GPM.
6. OUTLET HOSE: Hose from the outlet side of the
