A max flow of 140 GPM and max pressure of 160 PSI are only two features of the Ace cast iron hydraulic driven centrifugal pump. It also has a stainless steel shaft and a carbon/ceramic seal material. The e-coated cast iron material provides excellent durability. This pump is easy to maintain and high performing, giving you exactly what you expect in a centrifugal pump.

Ace developed the first hydraulic motor driven pump at the request of John Deere in 1969. Many of the original pumps are still operating today after more than 30 years of service. Centrifugal pump design provides good resistance to abrasive solutions and extra flow for agitation. The advantages of the hydraulic motor driven pump are mounting versatility, customized performance, and ease of maintenance. All hydraulic driven pumps are equipped with a stainless steel shaft and wear ring for excellent corrosion resistance. MOUNTING VERSATILITY: The location of the pump is not tied to the PTO or engine drive shaft; the pump can be mounted in a variety of locations to suit application requirements. CUSTOMIZED PERFORMANCE: The performance is dependent on the supply of hydraulic oil to the motor and not necessarily tied to engine speed. A hydraulic driven pump can produce higher pressures than PTO or belt driven pumps. They can also hold constant pressure at varying engine speeds on closed center hydraulic systems. EASY MAINTENANCE: On a hydraulic driven pump there are no belts to align or break. Separate pump and hydraulic motor shafts simplify repair and replacement. Two main pump bearings support shaft loads. All pumps are equipped with easily replaceable Viton® mechanical seals. The Ace gear type hydraulic motor is more efficient than gerotor type motors, and is less subject to damage by contamination than the gerotor design. A built-in needle valve allows for the bypass of up to 9 GPM excess hydraulic fluid on open center systems. The standard motor has a reverse flow check valve which prevents backward hookup and a coasting check which protects the motor seal from the flywheel effect of the impeller. A restrictor orifice is included with pump models recommended for pressure compensating closed center systems. ¥ Modified impeller design develops higher pressure at lower RPM. ¥ Durable E-Coat finish provides extra corrosion resistance on all surfaces inside and out. ¥ Oversized bearings for extended pump life. ¥ Splined motor to pump shaft connection strengthens the power train while allowing for easy repair and maintenance. ¥ 4000 PSI high efficiency pressure plated gear motor provides higher output with less oil flow. ¥ The M16 motor requires 14 GPM (53 LPM) maximum hydraulic fluid input. Recommended for: ¥ Pressure Compensating Closed Center Systems ¥ Load Sensing Closed Center Systems ¥ Open Center Systems up to 14 GPM (53 LPM)
