Grounding

WARNING

FIRE AND EXPLOSION HAZARD This pump must be grounded. Before operating the pump, ground the system as explained below. Also, read the sec- tion FIRE AND EXPLOSION HAZARD, on page 4.

Polypropylene and PVDF are not conductive. Attaching the ground wire to the grounding lug will ground only the air motor. When pumping conduc- tive flammable fluids, always ground the entire fluid system by making sure the fluid has an electri- cal path to a true earth ground. See Fig. 1.

Never use a polypropylene or a PVDF pump with non-conductive flammable fluids as specified by your local fire protection code.

US Code (NFPA 77 Static Electricity) recommends a conductivity greater than 50 x 10–12Siemans/me- ter (mhos/meter) over your operating temperature range to reduce the hazard of fire. Consult your fluid supplier to determine the conductivity or resistivity of your fluid. The resistivity must be less than 2 x 1012 ohm-centimeters.

Ground all of this equipment:

DAir Motor: Connect a ground wire and clamp as shown in Fig. 1. Loosen the grounding screw (W).

Insert one end of a 12 ga (1.5 mm@) minimum ground wire (Y) behind the grounding screw and tighten the screw securely. Connect the clamp end of the ground wire to a true earth ground. Order Part No. 237569 Ground Wire and Clamp.

NOTE: When pumping conductive flammable fluids with a polypropylene or a PVDF pump, always ground the entire fluid system. See the WARNING on page 6.

DAir and fluid hoses: Use only electrically conductive hoses.

DAir compressor: Follow the manufacturer’s recom- mendations.

DAll solvent pails used when flushing: Follow the local code. Use only metal pails, which are conduc- tive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which inter- rupts the grounding continuity.

DFluid supply container: Follow the local code.
