Product Introduction
The Series is a Horizontal End-Suction Fire Pump Set, a robust and highly dependable unit that serves as a cornerstone of modern fire protection systems. This pump set is engineered and manufactured in strict accordance with NFPA 20 standards and is UL Listed and FM Approved for life-safety service. Powered by a reliable listed electric motor, its primary function is to automatically boost water pressure to the levels required by sprinkler and hydrant systems. The pump represents a time-tested, durable, and efficient solution for facilities with an above-ground water source and adequate pump room space.
Design Philosophy & Construction
The pump is built as a complete, skid-mounted assembly, prioritizing reliability, serviceability, and strict adherence to fire safety codes.
- Horizontal End-Suction Pump: The unit is built around the industry-standard ISW-type end-suction centrifugal pump. This design features a horizontal shaft with the water entering the pump casing axially (“end suction”) and being discharged vertically from the top.
- “Back Pull-Out” Design: A key feature for serviceability, this construction allows the entire rotating assembly (impeller, shaft, seal, and bearing housing) to be removed from the back of the pump. This enables complete maintenance without ever disturbing the pump casing, motor, or the connected piping.
- NFPA 20 Compliant Materials: All wetted components, including the rugged cast iron casing and bronze-fitted impeller, are designed to withstand the high pressures and demanding conditions of fire service.
- Long-Coupled, Baseplate Assembly: The pump and its electric motor are mounted in-line on a common, heavy-gauge steel baseplate. They are connected by a flexible coupling, which is protected by a sturdy safety guard. This robust, long-coupled design provides excellent stability and makes it easy to service either the pump or the motor independently.
- Listed Electric Driver & Controller:
- UL/FM Listed Motor: The pump is driven by a high-efficiency UL/FM listed electric motor, specifically designed for the high-torque, instant-start demands of a fire pump application.
- Controller Integration: The pump set is designed to be governed by a separate UL/FM listed fire pump controller, which provides the fully automatic operation, monitoring, and testing functions required by NFPA 20.
Key Features & Benefits
- NFPA 20 Compliant & UL/FM Listed: Provides the highest assurance of reliability and performance, meeting all legal, code, and insurance requirements for life-safety equipment.
- Proven Durability & Robustness: The horizontal, baseplate-mounted design is a time-tested configuration known for its exceptional durability and ability to provide decades of reliable service.
- Superior Serviceability: The back pull-out feature significantly simplifies and speeds up maintenance, while the open, baseplate layout provides easy access to all components, including the coupling and motor.
- Clean & Quiet Operation: The electric motor drive provides clean, emission-free operation with low noise and vibration, making it the ideal choice for indoor installations in occupied buildings.
- Wide Performance Range: This classic design is available in a vast array of sizes, flow rates (GPM), and pressure ratings (PSI), allowing it to be precisely matched to the hydraulic demands of any fire protection system.
Common Applications
The pump is the standard, go-to fire pump for a wide variety of facilities with reliable electrical power and a positive suction water source.
- Commercial & Industrial Buildings: The most common fire pump installed in warehouses, factories, shopping malls, schools, and mid-rise office buildings.
- Sprinkler & Hydrant Systems: Serves as the primary pump to provide the required water pressure and flow for automatic sprinkler systems, standpipes, and fire hydrants.
- Positive Suction Sources: Ideal for installations that draw water from a reliable source that is level with or above the pump, such as a city water main or an above-ground storage tank.
- Primary Electric Pump: Often installed as the main fire pump in a system, sometimes paired with a diesel-driven backup pump in facilities requiring the highest level of redundancy.
