Peerless - Model AEF -Horizontal Fire Pumps for Commercial and Industrial Applications
Peerless horizontal fire pumps are meticulously engineered for commercial, industrial, and energy sectors, as well as fire safety applications. These pumps meet rigorous standards set by Underwriters Laboratories (UL) and Factory Mutual Research Corporation (FM), adhering to the National Fire Protection Association (NFPA) Pamphlet 20. They offer capacities from 250 to 5,000 gallons per minute (57-1,136 m3/hr) and can generate a head between 92 and 664 feet (28-202 m), with pressures ranging from 40 to 288 psi (2.75-19.8 bar). With a maximum horsepower of up to 1,000 hp (745 kW), these pumps are suitable for ambient temperature operations and can be driven by either electric motors or diesel engines. They are constructed from durable materials like cast iron and bronze, with optional materials available for sea water compatibility. Whether for potable, non-potable, or salt water, Peerless fire pumps provide reliable and efficient solutions for diverse water transfer applications.Peerless fire pumps are designed and manufactured to high standards of quality in materials, construction and workmanship. Peerless horizontal fire pumps are constructed in accordance with the requirements of Underwriters Laboratories (UL) and Factory Mutual Research Corporation (FM) and comply with the standards of National Fire Protection Association (NFPA) Pamphlet 20.
- 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.
