Rotatable Wet Spline Pump Flanges Product Image

Chelsea has a rotatable Wet Spline option for the 277 and 278 series PTOs. The ability to index the output flange of the PTO 360 degrees provides the ability to maximize pump clearance between the transmission and frame rails where space is always at a premium. Torsional vibrations from today's diesel engines prematurely wear out the mating shafts between the PTO and pump. The Wet Spline output option helps provide extended shaft life.

899 Series PTOs

Product From Chelsea Products Division, Parker Hannifin Corp.

Because of the large physical size of the pumps used on oil field exploration and maintenance trucks, clearance has always been a challenge. Chelsea’s new 899 Series was designed with this in mind to provide maximum clearance for the 4700 Series transmissions. Another challenge is the torsional vibrations from today’s diesel engines that prematurely wear out mating PTO and pump splines. The Wet Spline System that lubricates the mating PTO and Pump shafts will increase the life of these components 7 to 10 times longer than a dry mating connection. The 899 features six speed ratios, eight output types and is a constant mesh shifter which is an excellent option for variable displacement piston pump applications.
