Buffalo - Model HSM/HSS -Double Suction Pumps

Heavy duty horizontally split casings simplify inspection and maintenance of rotating parts since piping does not need to be disturbed. Greater interchangeability has been achieved by shaft groupings to reduce inventory requirements. Double suction enclosed one piece type impellers are hydraulically balanced and secured to the shaft by feather key and locking collars for exact alignment. 316 stainless steel shafts are ground and polished for precision fit of all parts, and sized to provide less than .002” deflection. Grease lubricated deep groove bearings are shielded on one side to minimize contamination and over greasing. Bearings are designed for 150,000 hours minimum average life.
