Open Circuit Axial Piston Pumps Series 45 J Frame Danfoss Series 45 J frame open circuit piston pumps convert input torque into hydraulic power. Rotational force is transmitted through the input shaft to the cylinder block. The input shaft is supported by tapered roller bearings at the front and rear of the pump and is splined into the cylinder block . A lipseal at the front end of the pump prevents leakage where the shaft exits the pump housing. The spinning cylinder block contains nine reciprocating pistons. Each piston has a brass slipper connected at one end by a ball joint. The slippers are held to the swashplate by the spring retainer and block spring. The block spring also holds the cylinder block to the valve plate. The reciprocating movement of the pistons occurs as the slippers slide against the inclined swashplate during rotation. Via the valve plate, one half of the cylinder block is connected to pump inlet and the other half to pump outlet. As each piston cycles in and out of its bore, fluid is drawn from the inlet and displaced to the outlet thereby imparting power into the system circuit. A small amount of fluid is allowed to “leak” from the cylinder block/valve plate and slipper/ swashplate interfaces for lubrication and cooling. Case drain ports are provided to return this fluid to the reservoir. The volume of fluid displaced into the system circuit is controlled by the angle of the swashplate. The swashplate is forced into an inclined position (into stroke) by the bias spring. The servo piston opposes the action of the bias spring forcing the swashplate out of stroke when hydraulic pressure in the control circuit rises above the spring force. The pump control, by varying the pressure at the servo piston, controls the displacement of fluid in the system circuit. Controls designed for Pressure Compensation (PC) or Load Sensing (LS) are available. For a detailed description of control operation, refer to Control options.

Product Details:

Series 45 hydraulic pump are comes with a single servo piston design with a cradle swashplate set on polymercoated journal bearings. Also have biased spring & internal force increase the swashplate angle. Servo piston are there for lowering the swashplate angle.
