Mississauga, Ontario, October 2013. Global pump maker KSB announces the new RPHmdp series of zero-leakage mag-drive pumps with back-pull out design. These horizontal, radially split volute casing pumps, which comply to US standard API 685, have been developed to reduce maintenance costs and to ensure a long service life. To achieve this goal KSB engineers in South Africa designed the pump, combining KSB’s proven and durable RPH hydraulic system with a state-of-the-art magnetic drive. The pumps are primarily used for handling hazardous fluids – such as hydrocarbons containing benzene –, which are subject to very strict emissions regulations. They are also well suited for the transport of clean, explosive, toxic and high-value fluids in petrochemical plants and refineries. Depending on requirements concerning eddy current loss and efficiency, various material options for containment shrouds are available. These include a carbon fibre-reinforced PEEK containment shroud that offers a high level of corrosion resistance and zero eddy current losses. The pumps feature very low vibration levels during operation as each pump rotor is subject to static and dynamic balancing in the manufacturing process. Patented plain bearings ensure that heat is dissipated efficiently and that any particles that enter the magnetic coupling chamber are quickly expelled. These technical features all serve to increase the pumps’ service life. The type series is designed for flow rates of up to 300m3/h and a maximum head of 270 m. Permissible operating temperatures range from -40 °C to +300 °C. Final pump set assembly is performed in Brazil, India, Argentina, South Africa and Germany, ensuring that these pumps are quickly available worldwide and can be readily matched to local requirements.
