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. Components Patented Jacking Mechanism simplifies seal replacement – one person operation (Split Coupled version only). Ductile Iron Casing long life with higher working pressures. Standard C-Face Motor provides low noise level pump operation (Split Coupled version only). Back Pull-Out Casing includes in-line suction and discharge. Case Wearing Ring prevents wear on casing and is inexpensively replaced. Impeller wear rings are optional. Investment Stainless Steel, Dynamically Balanced, Enclosed Impeller keyed to the shaft extension and secured by a capscrew and washer. Gaskets are used to prevent leakage to shaft end. Stainless Steel Shaft designed for minimum deflection. Mechanical Seal has carbon against ceramic face for optimum hot water performance. Long life is assured with 303 SST metal parts and Buna-N flexible elastomers (outside balanced seal optional). Factory Hydro Test guarantees casting and seal integrity. Relief Line assures adequate venting of the seal chamber and lubrication of seal faces. Smooth Suction Passage vortex breaker helps to minimize pre-rotation.
