Connect the external EX4 Pump outside any slip tank for an efficient casting system. A 1" x 8' pouring hose with utility nozzle and inlet hose to connect the pump to tank are included. The pump is direct driven by a 1/2 hp motor with an 8' on/off electrical cord. Pumping capacity varies from four (4) to seven (7) gpm depending on model and slip viscosity. Recommended for use for small volume casting applications. The normal life expectancy is about 1600 hours before rebuilding is required.
