SMi is listed by Underwriter’s Laboratories(UL) and approved by Factory Mutual (FM) for manufacturing vertical fire pump with flow range from 100 US GPM to 2500 US GPM. and a pressure more than 300 PSI.

Design Features:
F-series Discharge Heads
Cast iron head, up to 350 psi discharge pressure. With inside profile for smooth discharge and less frictional losses. Steel guards for protection and easy maintenance.
Column Assembly:
Threaded column assembly, steel ASTM A-53 with ductile iron couplings. 416 SS line shafts and couplings, bronze bearing retainer with bearings to maintain alignment and are spaced to provide adequate shaft support.
Bowl Assembly:
The bowl castings are manufactured of robust cast iron in close-grained structure iron according to ASTM A48 CL30
with minimum 30,000 PSI tensile strength, and veined to guide water flow from one impeller to the next with maximum efficiency. bowls are enameled coated to enhance pump performance and efficiency.
The enclosed impellers are cast from high-grade bronze with flow passages hand finished to a smooth surface for minimum efficiency losses. All impellers are balanced statically and dynamically to avoid vibration and secured to the pump shaft with tapered lock collet.
The pump shaft is made from high-grade tensile strength stainless steel according to ASTM A276-T416 of a diameter sufficient to prevent distortion.
Bowl assemblies have varied specified components as heavy-duty sand collars, sand lugs, bowl bearings in bronze and rubber. To ensure long life under severe conditions, both rubber and bronze bearings (dual bowl bearings system) are used.
