Installation
Mountings
Caution
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 1-1/2 in. raised face
flange. Refer to Flange Connections on page 10.
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
IG
1. The pump fluid outlet (S) is a 1-1/2 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.
