JT182 Water Jet Pump
The JT182 is a single – stage axial – flow marine jet pump. It has an input power range of 5 – 222 kW (6.7 – 298 hp) and input speed of 2000 – 4000 rpm. The impeller diameter is 180 mm, and nozzle diameter is 120 mm (4.7 inches). The pump housing is made of aluminum alloy, while the spindle and impeller are of stainless steel.
It features mechanical steering and hydraulic reversing with a dual – bucket diversion type reversing bucket. Power input uses ISO – standard SWC120 universal joints or flanges of the same size. It holds a CCS certificate, meeting international marine safety standards.
Suitable for workboats, fishing boats, and lifeboats. When single – installed, recommended for boats up to 7 m (23 ft) long and 2 t (4409 lb) in weight. For twin – installed, up to 8 m (26 ft) long and 4 t (8818 lb). Factory – provided power – speed curves help with engine/motor compatibility, and adjustments can be made with gearboxes or custom impellers for non – standard RPMs.
The single pump has a net weight of 57 kg, water – containing weight of 17 kg, and gross weight of 90 kg. It comes in a plywood box for packaging. Comprehensive technical documentation is provided to assist with installation planning.
Advantages Of JT182 Water Jet Pump
No exposed components under the hull allow operation in shallow waters, sandbars, and rocky areas while protecting the impeller from damage, reducing maintenance downtime and predictable servicing schedules.
Enclosed high-speed components eliminate risks to marine life and swimmers while reducing underwater equipment damage potential.
Flush-mounted intake design minimizes drag, aligned thrust direction maximizes propulsion efficiency, and stator vanes recover rotational energy lost in propeller systems.
Instant zero-speed thrust enables zero-radius turning, independent of vessel speed, with full reverse achievable via reverse bucket adjustment without engine rotation changes. Multi-pump configurations provide lateral thrust.
Weight variations don’t overload engines – pumps maintain optimal power matching, extending engine lifespan while offering flexible auxiliary propulsion integration.
AWT’s advanced impeller/intake designs deliver superior high/low speed performance, rapid acceleration, and precise maneuverability through hydraulic/electronic control systems supported by global service networks.
Premium corrosion-resistant materials, precision-cast integral impellers, and fully-integrated factory-tested systems ensure long service life with simplified installation/maintenance processes.
