Why This Product

Two-Stage Design — High Pressure at Field-Ready Flow

Two-stage impeller design delivers high discharge pressure suitable for firefighting, agricultural spray, and high-head transfer applications where single-stage pumps cannot reach the required pressure.

Engine-Driven — Operates Without Utility Power

Engine-driven design provides firefighting and high-pressure pumping capacity independent of utility power — critical for rural fire suppression, emergency response, and remote agricultural operations.

NSF/NFPA Compatible

Designed to meet requirements for portable firefighting pump applications. Performance curves and pressure ratings are appropriate for NFPA 1901 and rural fire suppression applications.

Self-Priming

Self-primes from completely dry — no foot valve, no suction line preparation required. Critical for firefighting deployment where setup time directly impacts fire suppression effectiveness.

Cast Iron Volute — Field Durability

Cast iron construction withstands the mechanical abuse of emergency deployment and repeated transport. Impeller and wear ring are serviceable in the field with standard stocked replacement parts.

High Volume at Elevated Pressure

Engineered to deliver meaningful flow rates at elevated pressure simultaneously — not just high pressure at low flow. Performance curve is matched to the demands of actual firefighting and high-head applications.
