Primo S14FP-NH-ES Two Stage Fire Pump System
The Primo S14FP-NH-ES is a two-stage fire pump system designed for medium-sized setups. It features a 14 hp Davey firefighter twin impeller pump housed on a heavy-duty powder-coated steel frame. A 12-volt AGM battery and a pressure relief valve with gauge are included, supporting dependable operation in emergency scenarios. Best for: facilities that require robust on-site protection with a solid, all-in-one frame, and NH threaded connections for accessible installation. Caution: NH threading requires appropriate adapters or fittings for certain systems, so verify compatibility before integration.
Davey Firefighter 5 Two Stage Pump
The Davey Firefighter 5 two-stage pump offers a compact yet capable solution with multiple discharge ports (one 1.5″ outlet and two 1″ ports) and a 1.5″ inlet. It suits fire protection applications that demand a flexible discharge configuration and reliable high-pressure performance. Best for: small to mid-sized fire protection systems that need multiple outlets and efficient prime performance. Caution: ensure the plant layout accommodates multiple discharge lines to maximize the unit’s benefits.
AMT Pump 2MP5HR Engine Driven Two Stage Pump
The AMT Pumps 2MP5HR features a high-efficiency two-stage impeller designed for fire protection, wash down, and sprinkler applications. It includes a built-in flapper/check valve for self-priming up to 20 feet and uses cast aluminum with Viton/silicon carbide seals and EPDM O-rings. Best for: installations requiring rapid priming and strong high-pressure output, especially where aluminum construction supports weight and corrosion considerations. Caution: aluminum construction may be less durable in extremely harsh environments over long service periods; confirm environmental exposure before deployment.
2 HP Fire Pump Single Stage Pump (Contrast for Context)
This 2 HP unit is a single-stage design operating at 380V, delivering up to 6.5 m³/h flow with a head of up to 32 m. It serves as a reference point for comparing stage configurations and is best for compact, non-two-stage setups or as a supplementary unit in mixed systems. Caution: not a two-stage pump, so use only where single-stage performance meets the system’s requirements. Best for: tight spaces needing compact inline pumping with predictable pressure, when a true two-stage solution isn’t required.
Multiquip Bon Submersible Electric Pump
The Multiquip Bon submersible pump offers a compact, lightweight design with strain relief on the power cord and a cast aluminum housing. It is suitable for portable fire protection needs or temporary water transfer in emergency scenarios. Best for: temporary setups or spaces requiring mobility; better for short-term deployments rather than permanent installations. Caution: submersible units require appropriate water depth and outlet positioning to avoid air lock or overheating in prolonged use.
Buying Guide
- System integration: Confirm inlet and discharge sizes match existing piping. Two-stage designs typically provide higher pressure at lower flow, which is preferable for longer vertical runs or high-rise protection.
- Power source: Engine-driven units (gasoline or diesel) offer independence from electrical supply; electric units simplify maintenance but depend on power availability.
- Material and durability: Aluminum bodies reduce weight but may not endure harsh environments as well as steel. Cast components and Viton seals improve chemical resistance and longevity.
- Priming and priming capability: Look for self-priming features if the installation may suffer from air entry or siphoning conditions. A higher priming depth supports more flexible placements.
- Discharge configuration: Decide if multiple outlets are necessary. Some units provide multiple discharge ports for simultaneous firefighting operations or hose combinations.
- Maintenance and service: Consider frame accessibility, pump housing protection, and availability of replacement parts in your region.
Frequently Asked Questions
- What is a two-stage fire pump? A two-stage fire pump uses two impellers to deliver higher pressure at lower flow, improving performance for high-rise or long-hose deployments.
- Which pump should I choose for a small building? A compact two-stage pump with multiple discharge options, such as the Davey Firefighter 5 or Primo S14FP-NH-ES, is suitable for small to medium facilities.
- Do I need an engine-driven pump? Engine-driven pumps provide independence from electrical systems, which is useful in power outages or remote locations.
- What should I check before buying? Confirm inlet/outlet sizes, mounting compatibility, priming capabilities, and the ability to service or replace seals and gaskets locally.
- Is aluminum better than steel? Aluminum reduces weight and can resist certain corrosion types, but steel frames offer greater durability in harsh environments.
- Are submersible pumps appropriate for fire protection? Submersible models are generally for portable water transfer; verify they meet your fire protection code requirements for fixed systems.
