  • The casing material is a minimum of class 35 cast iron. To provide permanent alignment of bearings and all rotating parts, Peerless Pump casts the bearing bracket supports as a part of the lower casing half.
  • Renewable bronze casing rings are doweled and shouldered in the casing.
  • The double suction impeller is a single cast-bronze piece. Dynamic balancing gives the impeller vibration-free hydraulic and mechanical performance. The balancing also provides a longer bearing life and mechanical seal life. Keyed to the shaft with an 18-8 stainless steel key, the impeller aligns axially with threaded shaft sleeves.
  • Grooved impeller skirts (in combination with casing rings) extend the life of critical clearances and increase the mean time between preventative maintenance (MTBPM).
  • Peerless Pump standard mechanical seals are mounted over a bronze shaft sleeve and rated for temperatures up to 225°F.
  • The optional packed stuffing boxes hold a minimum of five packing rings. Split glands facilitate removal for repacking. The gland bolts are swing-type and made of steel with 18-8 stainless steel nuts. Water seal piping and lantern ring are optional. As standard, the upper casing features a tapped and plugged seal flush connection.
  • Replaceable bronze shaft sleeves protect the carbon steel shaft through the stuffing box. The shaft sleeves extend beyond the mechanical seal flanges (or packing glands) for maximum shaft protection. O-rings seal the sleeves. The shaft and shaft sleeves are available in stainless steel.
  • The bearings are single-row, deep-groove ball-type and grease-lubricated. Their average life is 100,000 hours. Double-row, outboard thrust bearings and oil lubrication are optional.
