The Danfoss FT1312 Proof Test Stand is a self-contained, easy to use
machine for hydrostatic testing of Danfoss hose assemblies. It is de-
signed to test using tap water as the test medium. Air pressure drives
the pump which pressurizes the water in hose lines to desired test
pressures.
The power unit on the FT1312 Hose Proof Stand operates on the simple
principle of a pressure magnification through differential areas in which
an air operated piston drives a smaller piston providing fluid flow at
high pressure. An air regulator provides the means of adjusting hydro-
static test pressure.

Weight
550 lbs.
Test Fluid
Tap Water
Air Requirements

Tooling
Standard Industrial Adapters
The tester should be installed on a solid floor capable of holding 750 pounds. An area 9.5 feet by 6 feet should be allocated for the machine and
working area.
Remove the clear plastic air lubricator bowl (adjacent to the air pressure regulator on the pump assembly) and fill it three quarters full with SAE 30
nondetergent oil.
Connect a tap water supply line to the 1/2” pipe port of the water shutoff valve located on the water pumping unit.
Connect a compressed air supply line to the male air coupling attached to the air pressure regulator on the water pumping unit.
NOTE:
For optimum performance, the air compressor should be capable of supplying 100 psi at a rate of 20 cubic feet per minute.
Pressure side of pump so pump can prime itself. Running the pump dry will damage the hydraulic piston and cylinder.
Screw down the pressure regulator slowly until pump starts (pump should start flow at 10 - 15 psi air. Increase air pressure to 40 - 45 psi and allow
pump to run, purging the air from the system.
CAUTION:
Where the pump will be connected to a source of air greater than 150 psi, a pop-off type safety valve set to relieve pressure at 150 psi
maximum is required in the air line to protect the pump.
