Electric Hydraulic Pump 120 VAC and 10,000 PSI. Useable oil volume: 6 quarts (5.7 liters). For use with all Greenlee benders. Handy pendant advance control. Low voltage pendant coupled to solid state motor controls eliminates contact arcing for greater reliability and longer life. Automatic or manual ram return selector valve provides more control from the pendant switch. Molded enclosure protects pump, motor and circuitry in tough working environments. Use with single-hose hydraulic systems with spring-return rams.
