Ace Pump Corp. recently announced the addition of three new pumps featuring the company’s popular 206 motor and built-in pulse width modulated (PWM) control valves. The addition of these models completes the full range of Ace hydraulically driven pumps with integrated PWM control valves. The 13 standard models allow PWM pump options for any size machine.

“The 206 motor requires 7 GPM (26.5 LPM) maximum hydraulic fluid input and is compatible with most tractor hydraulic systems,” noted Andy Randle, CEO of Ace Pump. “The pulse width modulated control valves allow equipment owners and operators to implement a PWM control regimen on pull-type sprayers, planters and fertilizer applicators. They provide quick rate changes for both constant and variable rate applications. In addition, the new 206 models include a pressure relief valve to prevent over-speeding of the hydraulic motor and the damage it can cause. And, the pump runs only as fast as necessary, minimizing the horsepower required and extending pump life.”

The new models are recommended for use with any pressure compensated closed center or load sensing closed center hydraulic system. These models include severe duty silicon carbide shaft seals along with the follow specifications:

• The cast iron FMCSC-HYD-206-PWM has 1-1/4” x 1” NPT ports.
• The cast iron FMCSC-150F-HYD-206-PWM includes 1-1/2” x 1-1/4” NPT ports and industry standard 220 x 200 flanged connections.
• The FMCSC-150FS-HYD-206-PWM is constructed of durable 316 stainless steel with NPT ports and industry standard flanged connections.
