Start-Up
Inspection
Every 680C metering pump is
tested for correct capacity at
maximum pressure capability
of the hydraulic bypass valve
before shipment. The
diaphragm cavity is fully
primed and remains so for
shipment. For shipping
purposes the gear and
hydraulic reservoir oil have
been removed. Sufficient
fresh PULSAlube oil is
included with the shipment for
refilling the gear and hydraulic
reservoirs.
Warning
1. Do not run pump without
oil.
2. Do not remove main gear
box cover while pump is
running.
3. Do not run pump with
coupling guard removed.
4. Do not put hands or fingers
in gear box or reservoir
when pump is running.
Filling Gear and Oil
Reservoirs:
Remove the pump cover and
fill both reservoirs with
PULSAlube oil to the top of
the gear box partition. Do not
overfill. PULSAlube oil is
compounded to serve as both
gear lubricant and hydraulic
transfer fluid. Check with
factory if substitute oils must
be used.
The cover assembly
incorporates a free acting
diaphragm to allow breathing
of the reservoir and at the
same time seal the reservoir
from the atmosphere. Be
sure the diaphragm is
properly positioned when
replacing the cover so that it
will seal on the gear box.
