PP80-9200RC 80 MPa (800 bar, 11600 psi)
Required air pressure: 0,65-1,0 MPa (6,5-10 bar, 94-145 psi)
Capacity:
PP70-9200RC (/VA80) 1070-200 cm
PP80-9200RC 710-130 cm
Total oil capacity: 9400 cm
Effective oil capacity: 9200 cm
Weight inc. oil:
PP70/80-9200RC 20 kg (44.1 lbs)
PP70-9200RC/VA80 28,3 kg (62,4 lbs)
All -9200RC models are equipped with a dipstick for easy control of oil
level.
PP70/80-9200RC is equipped with a remote control. This has two but-
tons that allow remote operation of the pump start/stop and release.
PP70-9200RC/VA80 is also equipped with four VA80 shut off valves and
a pressure gauge (Fig. 2, pos. V)
Safety feature
The pump is equipped with a safety valve that regulates the output pres-
sure. The safety valve is set to the maximum working pressure at the
factory.
Installation
Connecting compressed air
The pump requires a compressed air pressure of at least 0,6 MPa (6 bar,
87 psi) to develop hydraulic pressures of 70 MPa (700bar, 10150 psi)
and 80 MPa (800 bar, 11,600 psi). Make sure that the air pressure does
not exceed 1,0 MPa (10 bar, 145 psi) as this could damage the pump. To
ensure efficient operation and long life use clean compressed air with a
water trap. Connect the compressed air line using a G 1/4" coupling, as
shown in Fig. 2, item A.
Connecting the hydraulic hose
Connect the hydraulic hose using a G 1/4" coupling (Fig. 2, item P) or
use REHOBOT quick couplings.
Bleeding the hydraulic system
When hoses or tools are connected to the pump they can introduce air into the
hydraulic system, which could lead to operating problems. Bleed the system
by running the tool or cylinder through 3–4 cycles (by pumping out until fully
extended, then releasing) with no load. Make sure that the tool or cylinder is
kept lower than the pump to allow the air to flow back into the oil reservoir of the
pump. It may be necessary to top up the oil depending on the volume of air in
the connected hoses or tool, see Filling with oil.

Operation

Before pumping, the transport plug should be replaced with the supplied
vented oil plug, see Fig. 3.
NOTE! Ensure that the transport plug with sealing washer is mounted
before transporting the pump.
Starting
Press the start/stop button (Fig. 4, item P) on the control unit. The pump
will stop and maintain the achieved hydraulic pressure when the start/
stop button is released.
Releasing
Press the return button (Fig. 4, item R). Hold the button in until the cylin-
der has moved back to the desired position.
NOTE! If the pump is overfilled when pressure is released from cylinder/
tool, the excess oil will pour out through the vented oil plug.
Accessories
The pump can be equipped with accessories such as a REHOBOT gauge
AMT801 (Fig. 2, item M), gauge adapter, etc. It is possible to connect a
return pipe. All rams, accessories, and tools that are connected to the
pump must be designed for a working pressure that is equal to or higher
than the maximum working pressure of the pump. NOTE! The pump is
equipped with a safety valve on the hydraulic side. It has been factory-
set for maximum working pressure. The safety valve should ONLY be
adjusted by REHOBOT or a workshop authorized by REHOBOT. For simple
reduction of the hydraulic pressure, we recommend you to use a reduc-
tion valve for incoming compressed air.

Maintenance

When necessary lubricate moving parts such as the pneumatic piston
and valve with high-grade grease.
Service
For safety reasons it is important that all service and repair work is car-
ried out by trained personnel. If you are in the slightest doubt please
contact your dealer for information about the nearest authorised service
agent.
Filling with oil
Check the oil level before use. This is easily done using the dipstick on
the oil filler plug. Always measure the oil level with the cylinder or tool in
the lowest or retracted position. To ensure efficient operation use hydrau-
lic oil that conforms to ISO VG 10.
• Place the pump on a planar surface (Fig. 5).
• Unscrew the oil filler plug (Fig. 5, item A).
• Fill the oil reservoir through the filler hole until the oil level is
35 mm (1.38 in) measured from the upper edge of the lid.
Check that the oil level does not exceed the top mark on the
dipstick (Fig. 5, item B).
• Screw the oil filler plug back into place.
