Product Description Product DescriptionSeries 90 axial piston variable displacement pumps are of cradle swash plate design with variable displacement, and are intended for closed circuit applications. The flow rate is proportional to the pump input speed and displacement. The latter is infinitely adjustable between zero and maximum displacement. Flow direction is reversed by tilting the swash plate to the opposite side of the neutral (zero displacement) position.

Testing should be carried out to determine the proper orifice selection for the desired response.Electric Displacement Control (EDC), Options KA, KPThe electric displacement control uses an electro-hydraulic Pressure Control Pilot valve to control the pilot pressure. The Pressure Control Pilot valve converts an electrical input signal to a hydraulic input signal to operate a 4-way servo valve, which ports hydraulic pressure to either side of a double acting servo piston. The servo piston tilts the cradle swash plate, thus varying the pump's displacement from full displacement in one direction to full displacement in the opposite direction. The control has a mechanical feedback mechanism which moves the servo valve in relation to the input signal and the angular position of the swash plate. The electrical displacement control is designed so the angular rotation of the swash plate (pump displacement) is proportional to the electrical input signal. Due to normal operating force changes, the swash plate tends to drift from the position preset by the machine operator. Drift, sensed by feedback linkage system connecting the swash plate to the control valve, will activate the valve and supply pressure to the servo piston, maintaining the swash plate in its preset position.Hydraulic Displacement Control (HDC), Option HFThe hydraulic displacement control uses a hydraulic input signal to operate a 4-way servo valve, which ports hydraulic pressure to either side of a double acting servo piston. The servo piston tilts the cradle swash plate, thus varying the pump's displacement from full displacement in one direction to full displacement in the opposite direction. The control has a mechanical feedback mechanism which moves the servo valve in relation to the input signal and the angular rotation of the swash plate. The hydraulic displacement control is designed so the angular position of the swash plate (pump displacement) is proportional to the hydraulic input signal pressure. Due to normal operating force changes, the swash plate tends to drift from the position preset by the machine operator. Drift, sensed by feedback linkage system connecting the swash plate to the control valve, will activate the valve and supply pressure to the servo piston, maintaining the swash plate in its preset position.Manual Displacement Control (MDC), Options MA, MBThe manual displacement control device converts a mechanical input signal to a hydraulic signal that tilts the cradle swash plate through an angular rotation varying the pump's displacement from full displacement in one direction to full displacement in the opposite direction. The manual displacement control has a mechanical feedback mechanism which moves a servo valve in the proper relationship to the input signal and the angular position of the swash plate. The manual displacement control is designed so that the angular rotation of the swash plate is proportional to the mechanical input signal. The control is designed with an internal override mechanism which allows the mechanical input to be moved at a faster rate than the movement of the swash plate without damage to the control.Non-linear Manual Displacement Control (MDC), Option NAThe manual displacement control device converts a mechanical input signal to a hydraulic signal that tilts the cradle swash plate through an angular rotation varying the pump's displacement from full displacement in one direction to full displacement in the opposite direction. The manual displacement control has a mechanical feedback mechanism which moves a servo valve in the proper relationship to the input signal and the angular position of the swash plate. The manual displacement control is designed so that the angular rotation of the swash plate is progressive to the mechanical input signal. The control is designed with an internal override mechanism which allows the mechanical input to be moved at a faster rate than the movement of the swash plate without damage to the control.Other Product Recommend ApplicationSauer 90 pump are widely used in hydraulic systems of various industries such as lifting machinery, engineering machinery, metallurgy, mining, shipbuilding, forging press, etc.Company ProfileJinan Focor Machinery Co., Ltd (Hydraulic Department) established strategic cooperation with other China manufacturers, covering mining, mineral transaction, construction and agriculture machinery, spare parts and service.
