A 1250 GPM fire pump provides critical high-volume performance for residential, corporate, and industrial buildings. Z3 Corporation offers expert installations and maintenance tailored to NFPA‑20 standards. In this guide, learn key details—including pump‑with‑controller catalogues, weight specs, and leading brands—to help you choose reliable fire safety solutions.

What Is a 1250 GPM Fire Pump?

A 1250 GPM fire pump pumps 1,250 gallons per minute (≈4 731 L/min), suitable for large buildings, factories, and high-rise complexes. It meets NFPA‑20 standards for fire protection systems. Fire pumps of this size are commonly mounted in fire pump rooms or fire trucks. For example, Waterous CXV/CXS pumps reach this capacity using durable iron bodies and bronze impellers.

H2: 1250 GPM Fire Pump With Controller Catalogue

What the Controller Does

Most 1250 GPM fire pump with controller catalogue models include electric and diesel controls, automatic start, jockey pump control, and pressure sensors. Variable-speed controllers (VFD) maintain constant discharge pressure, reduce startup strain, and conserve energy.

Leading Controller Brands

• Master Control Systems introduced VFD controllers in 2003, gaining UL and FM approval.
• Manufacturers like Techtop offer controller‑equipped UL/FM/NFPA‑20 rated electric fire pumps rated 1250 GPM & 12 bar.

Fire Pump Systems Supplied By Z3 Corporation

Z3 Corporation supplies fully packaged 1250 GPM pump sets with controller, jockey pump, and electric/diesel engines. We ensure NFPA‑20 compliant auto/manual operation and robust fault protection.

1250 US GPM Fire Pump Weight and Mounting

Typical Weights

• Waterous CSU dual‑eye pump: ~587 lb pump body alone; total adds 152 lb for transmission.
• CXS end‑suction pump: ~228 lb plus ~152 lb transmission.

A full skid-mounted set with engines and controller can weigh over 1,200 lb. Z3 Corporation’s structural engineers assess weight and vibration for safe installation.

They offer flexible configurations: horizontal split-case or end-suction pumps, materials in cast iron or stainless steel, with capacities up to 2,000 GPM.
Z3 Corporation includes compatible Asenware units in our product offerings.

Naffco 1250 GPM Fire Pump With Controller Catalogue

(Naffco: National Fire Fighting Manufacturing FZCO)
They offer 1250 GPM split-case fire pumps with diesel engine and controller in UL/FM-certified skid-mounted sets.
Z3 Corporation can supply and maintain Naffco 1250 GPM pump systems, including full controller catalogues and commissioning support aligned with NFPA‑20.

Electric vs Diesel vs Dual-Power Systems

• Electric-driven units: Efficient and compact; require reliable construction-site power.
• Diesel standby: Offer backup during grid outages.
• Dual-power (electric + diesel + jockey): Provide the most reliable coverage and automatic switching.

Z3 Corporation recommends dual-power systems for critical buildings like hospitals and data centers, ensuring constant firewater supply.

NFPA‑20 & UL/FM Requirements

NFPA‑20 mandates fire pump flow tests, automatic start, and performance reliability under fire conditions. Many 1250 GPM pump sets are UL-listed and FM-approved. Techtop electric models, for example, hold UL/FM/NFPA‑20 certification.
Z3 Corporation ensures all installed pumps and controllers meet NFPA‑20, UL, FM, CE, and ISO‑9001 standards.

H2: Performance & Maintenance Insights

• Performance: Choosing dual-stage vs single-stage impacts efficiency. Dual-stage pumps offer better low-flow performance and longevity.
• Weight & footprint: Heavy pump installations require reinforced foundations—Z3 provides structural assessment.
• Maintenance: NFPA‑25 recommends weekly 10‑min pump testing. VFD controllers reduce water waste during tests. Z3 offers full test & servicing support.
