Shut down & care of pump
For Overnight shut down, 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 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 static electricity (sparks or small shocks while in contact with the
equipment) 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 the pump
Always use the following procedures for grounding the 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 12 gauge wire and tighten the lock screw securely. The other end of
the ground wire must be secured to a true earth ground.
Grounding procedures
Grounding of the pump and all the other dispensing equipment is necessary to minimize
the possibility of sparks due to static electricity. Grounding must be in compliance with
local electrical codes. Check with local authorities for requirements in your area and with
the type of equipment being used. Ensure that all the following equipment is grounded:
1.
Air compressor:
Follow the grounding procedures as recommended
by the compressor manufacturer.
