DE STA CO's Single-Stage Pumps are continuous pressure reciprocating, stall-type pumps: Air pressure is simply converted to hydraulic pressure. Operated by any compressed air source, these pumps save energy by stalling when pressure is developed, and require no energy use to maintain system pressure. Consult factory for pump-mounted valves.
