1 1/4" Suction x 1" Discharge Pump; 100 PSI, 4600 RPM, 75 GPM, 3 GPM Hydraulic Motor; Open Center System; FMC-HYD-203
The 203 motor required 2 GPM (7.6 LPM) and 3 GPM (11.4 LPM)hydraulic fluid input. Recommended for engineered systems with limitedoil flow.
Ace developed the first hydraulic motor driven pump at the request ofJohn Deere in 1969. Many of the original pumps are still operating todayafter more than 30 years of service.
Centrifugal pump design provides good resistance to abrasive solutionsand extra flow for agitation. The advantages of the hydraulic motordriven 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 orengine 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 ofhydraulic oil to the motor and not necessarily tied to engine speed. Ahydraulic Roundup logodriven 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 alignor 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 typemotors, 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.
