Ace Pump Corporation Introduces New 255 Series PRO Pumps


Ace Pump Corporation today announced the introduction of its new 255F-HYD PRO 5 Series pumps with advanced features to improve reliability and prevent costly downtime.

“The new PRO 5 FMCSC models feature a severe duty silicon carbide seal that resists scratching from abrasive materials,” noted Ace Sales Manager Bobby Robinson, “plus a stationary face with O-ring seat transferring heat into the casting to improve seal survival during short run-dry events. The PRO 5 FMCWS models incorporate Ace Pump’s exclusive Oasis WetSeal Technology to isolate the seals from abrasive and corrosive materials and prevent run-dry failure of any length.”

According to Robinson, the new models include the following features:

A compact design with close-coupled motor for easy service and replacement

High-efficiency, gear-type motors that provide higher performance with less oil flow

A maximum flow rate of 260 GPM for both 304 and 306 models

Maximum pressure of 120 PSI for 304 models and 130 PSI for 306 models

Larger bearings for longer pump life

Stainless steel shafts and wear rings

Reliable thermoplastic impellers with stainless steel hubs

Durable e-coated castings for added corrosion resistance

Internal coasting check to prevent damaging pressure spikes when turned off

Integrated 12V proportional control valve and pressure relief valve in the 304 PWM models for use in precision applications using pulse-width modulated control systems

Standardized components within the PRO 5 Series:

A unique design that allows interchangeability while simplifying parts inventory

A common frame that accepts the new 200N5 and 300N Series motors

“These new PRO 5 products are ideal for use in a wide range of applications, from spraying and fertilizer application to fluid circulation and transfer,” Robinson added. “We feel confident they will help our customers avoid costly downtime during critical application periods.”
