Installation
Mountings
The pump exhaust air may contain contaminants. Ventilate
to a remote area if the contaminants could affect your fluid
supply. See Air Exhaust Ventilation on page 12.
1.
Be sure the mounting surface can support the weight of
the pump, hoses, and accessories, as well as the stress
caused during operation.
2.
For all mountings, be sure the pump is bolted directly to
the mounting surface.
3.
For ease of operation and service, mount the pump so
the air valve cover (2), air inlet, and fluid inlet and outlet
ports are easily accessible.
4.
Rubber Foot Mounting Kit 819.4333 is available to
reduce noise and pump movement during operation.
5.
Prolonged exposure to UV radiation will degrade natural
polypropylene components of the pumps. To prevent
potential injury or equipment damage, do not expose
pump or the plastic components to direct sunlight for
prolonged periods.
Fluid Suction Line
1.
The pump fluid inlet (R) is a 2 in. raised face flange.
Refer to Flange Connections on page 10.
Caution
2.
If the fluid inlet pressure to the pump is more than 25% of
the outlet working pressure, the ball check valves will not
close fast enough, resulting in inefficient pump
operation.
3.
At inlet fluid pressures greater than 1.05 bar, diaphragm
life will be shortened.
4.
See the Technical Data on page 33 for maximum
suction lift (wet and dry).
Fluid Outlet Line
Warning
A fluid drain valve (J) is required to relieve pressure in
the hose if it is plugged. The drain valve reduces the risk
of serious injury, including splashing in the eyes or on
the skin, or contamination from hazardous fluids when
relieving pressure. Install the valve close to the pump
fluid outlet. See F
. 2.
IG
1.
The pump fluid outlet (S) is a 2 in. raised face flange.
Refer to Flange Connections on page 10.
2.
Install a fluid drain valve (J) near the fluid outlet. See the
Warning above.
3.
Install a shutoff valve (K) in the fluid outlet line.
