Finish Thompson’s Static Protection 
Kit (SPK) is recommended to help prevent the accumulation of static charge when transferring flammable or combustible liquids. It is to be used in conjunction with stainless steel drum pumps and air or explosion-proof electric motors.
When pumping flammables at high flow rates, a static charge can build up due to the high velocity at which the fluid is moving. Static charge can become a spark capable of igniting flammable liquids. This is rare occurrence, but it is wise to prevent the possibility by using the SPK. Keeping the velocity of the liquid low significantly reduces these hazards. Our metal tube pumps combined with an appropriate motor and static protection kit is an engineered package designed to provide customers with a high level of protection when pumping flammable liquids.
The SPK is a conductive, 4-foot long x 1-inch I.D. cross-linked polyethylene discharge hose with grounding cables to bond the pump, motor, hose and receiving drum. It will also limit the pumps output velocity to 3-feet/second maximum (about 7 gpm through a 1’’ hose), which will reduce the
hazards of static build-up.
Custom hose lengths are available. Please contact the factory for additional information.
