FMC-75-HYD-204 Poly Centrifugal pump

The Ace FMC-75-HYD-204 combines a corrosion-resistant polypropylene centrifugal pump with an efficient, low-flow hydraulic motor. It is designed for smaller sprayers and low-volume chemical applications that do not require the excess flow, hydraulic demand or heat generated by a larger pump.

The pump delivers up to 25 GPM and a maximum shutoff pressure of 100 PSI. Its tall-blade polypropylene impeller helps develop the pressure needed for spraying while maintaining sufficient flow for bypass and tank agitation.

The FMC-75-HYD-204 uses Ace’s 204 hydraulic motor, which requires a maximum hydraulic oil input of 4 GPM. Ace recommends this configuration for pressure-compensating closed-center hydraulic systems and open-center systems delivering up to 13 GPM when the pump’s internal needle valve is used to bypass excess hydraulic oil.

The polypropylene volute, bracket and impeller provide corrosion resistance for compatible agricultural liquids. A stainless-steel pump shaft and internal hardware add durability, while the standard carbon/ceramic mechanical seal uses Viton elastomers for compatibility with many commonly applied fertilizers and crop-protection products.

Common Applications

The Ace FMC-75-HYD-204 may be used for:

• Starter fertilizer application
• In-furrow chemical application
• Small agricultural sprayers
• Compact boom sprayers
• Spot-spraying equipment
• Compatible liquid fertilizer application
• Compatible herbicide and pesticide application
• Tank agitation
• Turf and grounds-maintenance sprayers
• Tractor-mounted spray equipment
• Utility and skid sprayers
• Replacement of compatible roller pumps
• Replacement of compatible 12-volt diaphragm pumps

Ace specifically positions the FMC-75-HYD series as a hydraulic alternative to 12-volt diaphragm and roller pumps for starter-fertilizer and small-sprayer applications. 

Hydraulic-System Compatibility

The FMC-75-HYD-204 is recommended for:

• Pressure-compensating closed-center systems
• Open-center systems producing up to 13 GPM, using the pump motor’s internal needle valve to bypass excess hydraulic flow

The 204 motor uses up to 4 GPM to operate the pump. Its integral needle valve can bypass up to approximately 9 GPM of additional oil, allowing the assembly to work with an open-center system producing as much as 13 GPM.

The 204 motor is not Ace’s preferred choice for every load-sensing closed-center system. For broader tractor compatibility—including load-sensing systems—consider the FMC-75-HYD-206 with its 7 GPM hydraulic motor. 

Important: Hydraulic-system type, flow and pressure must be confirmed before ordering. Excess hydraulic flow or an incorrect installation can damage the motor, pump or tractor hydraulic system.
