Shutdown
For overnight shutdown, follow the Pressure Relief Procedure . Always stop the pump
at bottom of the stroke to prevent the fluid from drying on the exposed displacement rod and
damaging the throat packing
.
Hazards from fire or explosion
Hazards exist where sparks can ignite vapors or fumes from combustible chemicals or other
hazardous conditions exist such as explosive dust, etc. These sparks can be created from
plugging in or unplugging an electrical supply cord or from the static electricity generated by the
flow of fluid through the pump and hose.
Every part of the equipment must be properly grounded to prevent static electricity from
generating a spark and causing the pump or system to become hazardous. These sparks can
cause a fire, explosion, property and equipment damage and serious bodily injury. Ensure that
the pump and all components and accessories are properly grounded and that electrical supply
cords are not plugged in or unplugged when these hazards exist.
Should any evidence of sparks or static electricity exist, discontinue pump operation
immediately. Investigate the source of the static electricity and correct the grounding problem.
Do not use the system until the grounding problem is repaired.
Grounding procedure
Grounding of the pump and all components are necessary to minimize the possibility of sparks
due to static electricity. Grounding must be in compliance with local electrical codes. Check with
the local authorities for requirements in your area and with the type of equipment being used.
Ensure that all the following equipment are grounded correctly:
1. Pump : Loosen the lock screw to allow insertion of one end of a minimum
sized 12 gauge wire into the bore hole of the grounding lug. Insert wire
and tighten the lock screw securely. Secure the other end of the
ground wire to a true earth ground. See FIG. A
