Installation Tips
Check The Shipment
A standard PULSA Series
shipment includes the pump,
PULSAlube oil, wrenches,
instruction and parts list
packet and replacement parts
if ordered. Unpack carefully,
check packing list and make
sure all parts are received.
Check voltage of electric
motor against the service to
be used.
Locating the 680C Pumps:
PULSA 680C pumps are
designed to operated under
indoor atmospheric
conditions. It is desirable to
provide a hood or covering for
outdoor service. Alternate oil
or external heating must be
arranged if ambient
temperatures will be below
40 F (4.4 C). Fluid
o o
temperatures entering the
pump must be 40 F (4.4 C) or
o o
greater. Check with factory if
concerned with the suitability
of the operating environment.
1. Check level of pump. Shim
where necessary.
2. Securely bolt to foundation.
Do not distort base.
NOTE: Most 680 models will
operate without bolting down.
However, it is important to
have a solid and level
foundation so that a minimum
of vibration is evident.
Continual vibration can
loosen gaskets and pipe
connections.
3. Check motor alignment back pressure valve should

operation. Follow bolt
torque readings carefully.
Flooded Suction Desirable:
Installation will be simpler to
operate if the liquid will flow to
the pump by gravity.
Wherever possible the pump
should be located below the
level of storage vessel.
Discharge Pressure:
All 680 models are designed
for continuous service at the
rated discharge pressure. To
prevent liquid flow through, it
is necessary that discharge
pressure be at least 5 psi
above suction pressure.
