The K-Tool International Lever Transfer Pump, No. KTI72210, is designed for use with high viscosity oils. The materials used in the barrel pump construction allow for use with water based media, as well. Its built-in, 2” bung adapter allows the pump to be fixed on drums with a 2” opening. The lock nut incorporated in the pump body allows for the pump position to be adjusted. The siphon action can be broken by loosening the air vent cap that is fitted on the pump outlet. The supplied suction tube can be used with 15 to 55-gal drums and a 2m by 3/4" flexible corrugated discharge hose is also included. The Lever Transfer Pump should only be used with non-flammable liquids.
