Fairbanks Nijhuis Vertical Inline Close Coupled Pumps are specifically designed for mounting, in any position, directly in a pipe line. The suction and discharge nozzles are located on the same centerline 180º apart. Vertical pumps significantly reduce the space required; two pumps fit in the space of one. They are easy to maintain; simply remove the cap screws and the motor and bracket assembly is easily removed from the casing without disturbing the piping.
