6 IPM transfer pumps incorporates a wet tube, the purpose of which is to prevent the buidup of
chemical and dirt on the pump shaft which would damage the packing as the shaft
reciprocates through them. This wet tube must be full when a pump that has not been
thoroughly flushed and cleaned is stored outside the protected environment of a sealed drum
as well as when the pump is in use. Should a pump be installed in a partially filled drum
where the liquid level is below the top of the wet tube, the tube must be manually filled with
the proper chemical prior to inserting into the drum.
7 Once a pump is committed to a particular chemical, it is good practice to identify which
chemical a particular pump is designated for to eliminate the possibility of mix up and
contamination.
Shut down & care of pump
For overnight shut down, follow the Pressure Relief Procedure (page 5) . 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.
