Installation Instructions
NOTE: The reference letters in the following instructions
refer to
Typical Installation , page 5.
Mounting the Pump
• Select a convenient installation location for the
equipment to ensure easy operator access to the
pump air controls, sufficient room to change supply
containers, and a secure mounting platform.
• For mounting the pump directly onto the supply
container, position the pump so that the intake valve
is no more than 1 in. (25 mm) from the bottom of the
container. Mount the pump to the drum cover (K) or
other suitable mounting device.
Pump Accessories
Drain Valve (M): used to relieve fluid pressure in the
pump.
Shut-off Valve (N): used to isolate the pump from
downstream fluid pressure.
Fluid Pressure Gauge (P): monitors the fluid outlet
pressure.
Air Line Accessories
Install the air line accessories (not supplied) as shown in
Typical Installation , page 5.
• Install a bleed-type master air valve (E) (required)
within easy reach of the pump, downstream from the
air regulator (C) (required).
• Install an air filter (B) (optional) to remove harmful
dirt and moisture from the compressed air supply.
For automatic air motor lubrication,
• Install an air line oiler (D) (optional) close to the
pump air inlet.
• Install an air regulator (C) (required) to control the
pump speed.
• Verify that the air hose is properly sized to deliver an
adequate supply of air to the motor. Refer to
Technical Specifications , page 26.
Mount the pump securely so that it cannot move
around during operation. Failure to do so could result
in personal injury or equipment damage.
Maximum Working Pressure of Accessories
To reduce the risk of serious injury including fluid
injection and splashing in the eyes or on the skin
which may be caused in component ruptures, all
accessories added to the pump fluid outlet side must
have the following maximum working pressures:
• Models 25P784 and 25P785: at least 20,000 psi
(137.9 MPa, 1379 bar) maximum working
pressure.
• Models 26A967 and 26A968: at least 12,000 psi
(82.7 MPa, 827 bar) maximum working pressure.
A bleed-type master air valve (E) is required to shut
off and relieve air pressure that may be trapped in the
air motor (L). Trapped air could cause the pump to
cycle unexpectedly and cause serious bodily injury,
including amputation.
