MBN MEDIUM PRESSURE

Stage Casing Pumps The MBN pumps are ideal for use in medium-pressure applications. They have a big variety of nozzle position options, thus providing flexibility during installation and simplifying the piping design. The thrust bearing and shaft seal can be easily exchanged without disassembling the suction casing.
