Ace 255F-HYD Pro 5 Series Pumps feature a severe-duty silicon carbide seal that resists scratching from abrasive materials, plus a stationary face with O-ring seat transferring heat into the casting to improve seal survival during short run-dry events. Oasis WetSeal Technology isolates the seals from abrasive and corrosive materials and prevents run-dry failure of any length. The Pumps feature a maximum flow rate of 260 gpm and maximum pressure of 120 psi for 304 models and 130 psi for 306 models.

The Pump's unique design allows interchangeability while simplifying parts inventory. A common frame accepts the 200N5 and 300N Series motors. High-efficiency, gear-type motors provide higher performance with less oil flow. Internal coasting check prevents damaging pressure spikes when turned off. Optional integrated 12V proportional control valve and pressure relief valve in the 304-PWM models are offered for use in precision applications using pulse-width modulated control systems.
