A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump ...
The Abrasive Water Suspension Jet (AWSJ) - often called “Slurry Jet” or “Water Abrasive Suspension (WAS) jet” - is a specific type of abrasive water jet, which is used for waterjet cutting. In contrast to the abrasive water injector jet (AWIJ), the abrasive water suspension jet (AWSJ) [ 25 ] is characterised by the fact that the mixing ...
The JetLev is a water-propelled jet pack powered through a floater derived from jetski technology attached through an umbilical to the backpack which contains two nozzles and two control arms, in a configuration like traditional rocket belts and gas turbine jet belts. The JetLev also functions underwater, allowing users to dive into the water ...

[2] As of 2020 [update] it was the latest Pacific craft within the BAE Halmatic range, and has been proven in service with the UK MOD, UK police and overseas military and paramilitary organisations.
Water jet may refer to: A jet of water under pressure, like in an ornamental fountain or drain cleaner; Pump-jet, a marine propulsion mechanism for jetskis and other types of boats; Water jet cutter, a tool for cutting and the machining of engineering materials; Water-jet printer, a printer that makes use of water instead of ink; Dental water ...
The Kamewa waterjets are still traded by Kongsberg Maritime under that name and are offered in five product lines in two product series.. Previous products from Kamewa has been the A-series, a mix flow pump in aluminum, the SII and P62 pumps in stainless steel and the Kamewa Advanced Propulsion Systems (APS) Waterjet developed specifically for the Volvo Penta diesel engine.
Whereas park and pool hydraulophones are usually 12-jet diatonic, concert-hydraulophones are usually 45-jet chromatic. 45-jet hydraulophones have a 3 1 ⁄ 2 octave range of A to E, chromatic, plus an additional A-flat below the lowest A. The playing compass (45 water jets) is the same as the sounding range (45 notes).
Moving water, river flow or strong tidal actions have posed the biggest danger to participants. When the jet ski and the floating rider move with the water, the 20+ meter long hose can hang up on underwater obstructions. This can pull the rider, and potentially the jet ski under water as the hose becomes taut.
