| 1 |
End-Suction Fire Pump |
25–500 gpm
(95–1,893 L/min) |
40–150 psi
(2.8–10.3 bar) |
Horizontal, close-coupled or long-coupled |
Small and medium commercial buildings, warehouses, and light industrial facilities |
Compact footprint, relatively simple maintenance, and competitive installation cost |
Confirm suction conditions, NPSH requirements, rated duty point, and applicable local certification |
| 2 |
Horizontal Split-Case Fire Pump |
250–5,000+ gpm
(946–18,927+ L/min) |
75–200 psi
(5.2–13.8 bar) |
Horizontal, base-mounted with separate driver |
High-rise buildings, industrial plants, storage facilities, and municipal fire systems |
High flow capability, stable operation, and convenient access to internal components |
Requires more floor space and careful alignment of pump, driver, coupling, and foundation |
| 3 |
Vertical Inline Fire Pump |
25–1,000 gpm
(95–3,785 L/min) |
40–150 psi
(2.8–10.3 bar) |
Vertical, installed directly in the piping line |
Commercial buildings, sprinkler systems, and projects with limited mechanical-room space |
Small floor area, simplified piping layout, and reduced foundation requirements |
Check pipe support, shaft alignment, maintenance clearance, and allowable system pressure |
| 4 |
Vertical Turbine Fire Pump |
500–5,000+ gpm
(1,893–18,927+ L/min) |
75–250 psi
(5.2–17.2 bar) |
Vertical shaft, often installed over a storage tank or well |
Facilities with water sources below the pump, large industrial sites, and dedicated fire-water tanks |
Suitable for negative suction conditions and deep or below-grade water sources |
Verify water level variation, shaft length, bowl setting, column design, and structural support |
| 5 |
Horizontal Multistage Fire Pump |
25–1,000 gpm
(95–3,785 L/min) |
100–400 psi
(6.9–27.6 bar) |
Horizontal, with multiple impellers in series |
High-rise buildings, pressure-zone systems, and specialized industrial protection |
Generates high pressure without requiring a very large impeller diameter |
Evaluate stage count, seal arrangement, water quality, and pressure relief requirements |
| 6 |
Vertical Multistage Fire Pump |
25–1,000 gpm
(95–3,785 L/min) |
100–400 psi
(6.9–27.6 bar) |
Vertical, compact, multistage arrangement |
High-rise sprinkler systems, compact pump rooms, and high-pressure water networks |
Small footprint and efficient production of high discharge pressure |
Allow sufficient vertical clearance and verify maintenance access for seals, stages, and couplings |
| 7 |
Vertical Mixed-Flow Fire Pump |
1,000–10,000+ gpm
(3,785–37,855+ L/min) |
50–150 psi
(3.4–10.3 bar) |
Vertical, usually with submerged or wet-pit intake conditions |
Large water-transfer systems, ports, refineries, and extensive industrial fire networks |
Handles high flow rates with moderate pressure and variable water levels |
Review intake hydraulics, submergence, debris protection, and minimum continuous flow |
| 8 |
Vertical Axial-Flow Fire Pump |
2,000–20,000+ gpm
(7,570–75,710+ L/min) |
30–100 psi
(2.1–6.9 bar) |
Vertical, wet-pit or tank-mounted installation |
Very large-volume fire-water transfer and flood-control-related fire protection systems |
Very high flow capacity with relatively low discharge head |
Best selected where high flow is more important than high pressure; check operating range carefully |
| 9 |
Rotary Positive-Displacement Fire Pump |
10–500 gpm
(38–1,893 L/min) |
100–300 psi
(6.9–20.7 bar) |
Horizontal or skid-mounted package |
Foam proportioning, water-mist systems, and specialized fire-suppression duties |
Provides controlled flow at changing pressure and can handle certain viscous fluids |
A properly sized relief valve is essential; verify fluid compatibility and maximum differential pressure |
| 10 |
Reciprocating Positive-Displacement Fire Pump |
1–100 gpm
(3.8–379 L/min) |
100–1,000 psi
(6.9–69 bar) |
Skid-mounted or packaged specialty system |
Special-hazard systems requiring high pressure at comparatively low flow |
Strong pressure capability and accurate low-flow delivery |
Consider pulsation control, relief protection, maintenance intervals, and the specific suppression medium |
