Janus high‑pressure axial piston pumps are purpose‑built for water‑mist fire‑suppression systems, delivering clean, oil‑free performance with flow rates up to 1000 L/min and pressures up to 160 bar.
Their stable, reliable output ensures fast, consistent activation of water‑mist nozzles in critical fire‑protection scenarios, while also supporting open‑ended misting, cooling, dust‑control, and humidification applications.
Designed and manufactured in Hull, UK, the pumps are engineered for long‑life operation in demanding fire‑safety environments. The axial‑piston design provides high output in a compact, lightweight package, with displacements from 0.8cc/rev to 625cc/rev to suit systems of any scale.
Each pump uses up to nine pistons to achieve exceptionally low pressure ripple — eliminating the need for accumulators and ensuring the stable, predictable pressure that certified water‑mist fire systems depend on.
All moving parts operate using water alone for cooling and lubrication, removing any risk of oil contamination and ensuring a fully clean fire‑suppression system.
Constructed entirely from 316 or duplex stainless steel, the pumps offer outstanding corrosion resistance for industrial, marine, offshore, and saline fire‑protection environments.
Flow output is easily controlled through input‑shaft speed, enabling precise metering for water‑mist nozzles and allowing system designers to match pump performance exactly to fire‑suppression requirements.
