Detailed Product Information

Product Description

LSDS1.9/1124 High-Volume Diesel Fire Water Pump is specifically designed for applications where sheer water volume matters more than pressure. With a tremendous flow rate of 1124 liters per second and a head of 19 meters, this unit is ideal for bulk water transfer, large-area fire suppression, and emergency flood control. Driven by the powerful Cummins NTA855-P470 diesel engine, it combines long-running durability with unmatched pumping capacity. It’s the go-to solution for industrial sites, port facilities, and municipal services needing fast water delivery on a massive scale.

Main Features

  • Ultra-High Flow Rate – Handles 1124 L/s (4046 m³/h) — making it suitable for wide-area fire protection, deluge systems, or rapid drainage in emergency scenarios.
  • Low-Head, High-Volume Application – With a 19-meter head, this pump is engineered for systems requiring high throughput over short or moderate vertical lifts.
  • Powered by NTA855-P470 – Equipped with a 351kW Cummins diesel engine, designed to run reliably in intensive, continuous operations.
  • Optimized for Water Transfer Speed – Its configuration ensures minimal resistance and maximizes output, making it ideal when time and water delivery are mission-critical.
  • Stable Suction Performance – With a Net Positive Suction Head (NPSH) of 6 meters, the system is suitable for large-diameter suction pipelines and consistent feed sources.
