MOOG RKP Radial Piston Pump

 

MOOG piston pump, the former BOSCH radial piston pump, BOSCH Group after the acquisition of Rexroth hydraulics, the 0514 piston pump unit sold to the world's largest servo valve production company MOOG company. German BOSCH manufactures radial piston pumps for more than 80 years. The MOOG piston pump is an important device of the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder, so that the volume of the sealed working chamber changes to achieve oil absorption and pressure. Piston pumps have the advantages of high pressure rating, compact structure, high efficiency, and convenient flow adjustment. MOOG Radial Piston Pumps have always been the first choice for high pressure hydraulic pumps and are widely used in applications where high pressure, high flow rates and flow rates need to be adjusted, such as Hydraulic presses, construction machinery, ships, military equipment, mining machinery, mining machinery, rubber and plastics machinery, injection molding machinery, ceramic machinery, presses, CNC machine tools, columnar presses, bending machines, steel mill equipment, and power plant equipment Wait. MOOG Radial Piston Pumps are equipped with automatic balancing valves. They are constant pressure variable pumps. After the working pressure is set (adjusted by balancing valve), the pump can automatically adjust the pump oil supply according to the needs of the system flow. Ensure the system pressure is stable. And the use of this constant pressure variable radial piston pump can achieve the purpose of energy saving, compared to other power pumps with the same power to save energy 30%. MOOG has changed the old BOSCH code 0514 series to the new MOOG number D950 series. The new pump is fully compatible with the original pump and its installation and performance are identical to those of the original numbered pump. MOOG, a leader in motion control technology, focuses on the manufacture and application of high-performance products. The radial piston pump product line (ie RKP pump) is a series of high performance variable displacement pumps for industrial applications. Based on proven concepts, the RKP's robust design extends service life and reliability. Its fast response time and high volumetric efficiency have become the first choice for many machines that require flow and pressure control requirements. We produce radial plunger pumps of various sizes, single and multiple arrangements, as well as various forms of control (mechanical, hydromechanical, electrohydraulic, digital and analog) in order to provide machine manufacturers with maximum flexibility.

The new generation of RKP-II radial piston pump is an upgraded product of RKP pump. Thanks to its flexible and high-performance design, the new RKP-II is the ideal solution for various industrial applications, especially for precision, speed, Energy consumption, noise, and adaptability require comprehensive consideration. They are widely used in general hydraulic applications such as injection molding machines, die casting machines, printing presses, and roll molding machines. They are also widely used in testing, construction, rubber molding equipment and mining. field. . RKP has been used in injection molding machines, die casting machines, forming equipment such as presses and rollers, as well as general hydraulic applications. In the field of plastics and metal processing, RKP is used in the production of plastic and metal parts equipment for the packaging and automotive industries. RKP is also used for testing equipment, construction, rubber processing and mining. The new RKP-II is particularly suitable for applications requiring power, low noise and rugged design, as well as accuracy and speed. The RKP-II pump control technology has been significantly improved with a new integral closed-loop proportional valve with digital on-board electronics for flow and pressure regulation, regulation and diagnostics. The RKP-II can be digitally controlled via the CANopen interface or controlled via analog command signals. The separate advantages of the RKP in CANopen or simulation mode are outlined in the separate catalog of the RKP-D pump.
