Mounting
The pump exhaust air may contain
contaminants. Ventilate to a remote area. See
Air Exhaust Ventilation on page 9.
Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure on page 10
before moving or lifting the pump.
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 ease of operation and service, mount the
pump so air inlet, fluid inlet and fluid outlet ports
are easy accessible.
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical current
due to static build up or in event of a short circuit.
In the site housing a grounding connection is
included.
Check your system electrical continuity after the
initial installation. Set up a regular schedule for
checking continuity to be sure proper grounding is
maintained.
Follow your local fire codes. When pumping
flammable fluids,
always
ground the entire fluid
system as described.
Air Line
See recommended installation drawing
on page 7.
1. Install an air regulator and gauge. Set pressure
of the driving air should be limited to the
pressure required to run the pump on the
desired working point. Setting the pressure too
high will cause higher wear of the pump and
will increase the compressed air consumption.
The fluid stall pressure will be the same as the
setting of the air regulator.
2. If the air regulator do not have a bleed off
function to relieve trapped air, or the air regulator
is not placed close to the pump, locate a bleed-
type master air-valve close to the pump. Be sure
the valve is easily accessible from the pump.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury
from splashing.
3. The master air valve will be used to regulate
the flow rate of the air to the pump. By using a
throttle valve, it is possible to regulate the pump
speed even at the lower end of the curves.
4. Install a grounded, flexible air hose between
the accessories and the pump air inlet. The
inner diameter of the hose have to be the same
diameter of the air connection of the pump or
bigger.
