Ruhrpumpen's Spotlight

We’re pleased to share a summary of a pre-engineered, UL/FM compliant fire protection pump house system designed to deliver reliable, code-compliant performance for critical facilities. The ETL-listed packaged pump house is engineered in accordance with NFPA 20, NFPA 13, and NFPA 72, with a total system capacity of 2000 GPM, a rated pressure of 110 psig, and a maximum working pressure of 250 PSI. The package includes two electric motor–driven main fire pumps and one jockey pump, all fully integrated to simplify installation and commissioning.

The main fire pumps are BB1, between-bearings, single-stage, axially split units (Model ZW 10x8x18 F), UL Listed and FM Approved, featuring cast iron casings with 316 stainless steel impellers, shaft sleeves, and case wear rings. The pumps are configured with packed shaft sealing and a Plan 7311 seal flush, grease-lubricated bearings with lip seals, and counter-clockwise rotation viewed from the driven end. Each pump is driven by a 250 HP, 1750 RPM UL-listed electric fire pump motor, operating at 480 V, 3-phase, 60 Hz, with TEFC enclosures and paired with UL/FM approved Tornatech controllers housed in NEMA 2 enclosures, complete with alarms, contacts, and motor heater connections.

System piping is supplied in carbon steel and includes individual suction and discharge lines with UL/FM OS&Y gate valves, swing check valves, and butterfly valves, as well as circulation relief piping. A complete flow test loop, hose valve header, and UL/FM approved flowmeter are included to support acceptance testing and long-term maintenance. The jockey pump is a vertical inline multistage unit rated at 20 GPM @ 120 psi, driven by a 3 HP electric motor with a UL-listed jockey pump controller.

The pump house structure is a fully insulated steel enclosure with a shed-style roof, engineered for wind loading and anchor bolt reactions, and equipped with multiple access doors, removable roof panels, and defined pipe penetrations. Electrical and auxiliary systems include a common power distribution panel, transformer, fire alarm and control panel, ventilation system, unit heaters, lighting, grounding, and cable management—all supplied as part of a turnkey package. The complete system undergoes hydrostatic, mechanical, and certified performance testing in accordance with Hydraulic Institute standards, providing customers and project teams with a robust, fully tested fire protection solution built for long-term reliability and compliance.
