INSTALLATION
To flush the pump, use an approved solvent com-
patible with the liquid being pumped.
Make cer-
tain that the solvent will not attack pump com-
ponents, particularly seals and gaskets.
PUMP INSTALLATION
Pump dimensions are shown in the separate
Pump Specification Bulletin.
Never operate the pump without a pres-
sure relief valve installed on the pump
or in the discharge piping. Make certain
that pump-mounted pressure relief
valves are installed with their adjusting
ends toward the suction port. If bi-rota-
tional operation is required, a pressure
relief device must be provided for both
directions of flow. Operation without a
pressure relief valve or with an improp-
erly installed relief valve could cause
the pump to explode, resulting in seri-
ous injury or death to personnel.
Lifting
Remove suction and discharge hose and piping
before attempting to lift the pump. Use lifting equip-
ment with a capacity of at least five times the total
weight of the equipment being lifted.
Positioning The Pump
Locate the pump as close as possible to the liquid
being pumped. Locating the pump below the liq-
uid source will help self-priming and reduce the
possibility of cavitation.
Mounting
The pump may be shipped alone, mounted on a
base, or with pump and motor mounted on a base.
Install the pump and motor on a base before
mounting the base on a foundation.
Mount the base on a foundation that will provide
permanent, rigid support for the pump, and will be
heavy enough to absorb any vibration, strain or
shock.
Piping
Before establishing suction and discharge lines,
determine pump port positions and rotation. Fig-
ure B---1 shows typical port positions for the stan-
dard 90
_
housing; if you have selected a 180
_
housing port option, your port positions will be dif-
ferent.
Either hose or rigid pipe may be used to make con-
nections. If rigid piping is used, install expansion
joints to protect the pump from vibration and ther-
mal expansion in the piping. Do not use expansion
joints or flexible connectors to adjust misaligned
piping.
Begin piping layout at the pump, and work toward
the source of supply and the point of discharge. If
an obstacle is in the way of a suction or discharge
line, run the piping
around
the obstruction, not
over it. Running piping over an obstruction will
create an air pocket which will make priming more
difficult.
If possible, slope the piping toward the pump so no
air or liquid is trapped in the piping. If a long hori-
zontal suction line is necessary, install the line be-
low the liquid level whenever possible in order to
keep the piping full of liquid. This will make priming
easier because the pump will not have to remove
as much air in the line.
