RKP Pumps

An important addition to Moog’s hydraulic products line is the well known RKP Pump. The complete product line was acquired by Moog Inc. February, 2001 and production was recently transferred to a new facility in Nuremburg, Germany. The product was originally developed by Bosch and has served the industrial market for over two decades. The modular nature of the RKP permits customized solutions and the design is characterized by high reliability, low noise levels, and rapid response in a compact package. There is a large selection of manual and electric-hydraulic control (EHV) options, as well as high pressure versions and pumps suitable for special fluids. At the recent Hannover Messe, Moog exhibited a new (EHV-D) version with fieldbus interface
