As a centrifugal pump, this is ready to provide resistance against abrasive solutions. It features extra flow and mounting versatility, too. The stainless steel shaft and wear ring mean less corrosion and easy maintenance, not to mention the superior performance you can expect from an Ace cast iron hydraulic driven 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. FS model constructed of 316 stainless steel with NPT ports and industry standard flanged connections. Provides higher pressure and greater volume for applications with large tanks and longer spray booms. The 310 motor requires 16 GPM (60.6 LPM) maximum hydraulic fluid input and fits virtually all tractor hydraulic systems. Recommended for: Open Center Systems up to 24 GPM (90.9 LPM) using internal needle valve bypass
