Engineering Specifications 1600 Series Specifications The contractor shall furnish (and install as shown on the plans) Fairbanks Nijhuis model (1650 horizontal close coupled) (1620 horizontal flexible coupled) back pull out centrifugal pump size x x of stainless fitted construction. Each pump shall have a capacity of gpm at ft of total head, with a temperature of F, specific gravity. Each pump is to be furnished with a mechanical seal with all metal parts to be 303 SST with Buna-N elastomers, ceramic seat, and carbon washer. The unit must be equipped with a stainless steel shaft sleeve that extends the length of the seal plate. The pump shaft extension shall be gasket sealed from the pumped liquid. Impellers to be 316 SST, dynamically balanced, and key locked to the shaft. Flexible Coupled Frame Mounted (1620) Pump and motor are to be mounted on a common fabricated steel base plate. The shaft is to be steel, installed in a cast iron power frame. Pumps shall have a shaft design of.002" deflection at the seal face with the pump running under maximum load condition. Greased ball bearings have a 3-year minimum life (AFBMA B10) under the maximum condition of load. The pump shall be flexible coupled to a standard horizontal NEMA hp phase Hertz volts rpm (open drip proof) (totally enclosed fan cooled) motor. Alignment shall be checked in accordance with the standards of the Hydraulic Institute after installation and there shall be no strain transmitted to the pumps.
