• The casing material is high-density cast iron, minimum tensile strength 35,000 psi. 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 provide sealing for minimum recirculation between the suction and discharge areas of 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.
• Packed stuffing boxes hold a minimum of five packing rings with water seal piping and lantern rings. Split glands made of 304 stainless steel facilitate removal for repacking. The gland bolts are swing-type and made of steel with 18-8 stainless steel nuts.
• 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 304 stainless steel shaft sleeves extend beyond the packing glands for maximum shaft protection. O-rings seal the sleeves.
• The bearings are single-row, deep-groove ball-type, and grease-lubricated. Their average life is 100,000 hours. Double-row, outboard thrust bearings are optional.
