Marine Water Jet Propulsion Pump

Water-jet Overview

_{Water-jet propulsion pump discharging of a high velocity jet stream generates a reaction force in the opposite direction, which is transferred through the body of the jet unit to the craft's hull, propelling it forward. It works in relation to Newton's Third Law of Motion – "Every action has an equal and opposite reaction". A good example of this is the recoil felt on the shoulder when firing a rifle, or the thrust felt when holding a powerful firehose.}

<sub>Steering System

Steering is achieved by changing the direction of the stream of water as it leaves the jet unit. Pointing the jet stream one way forces the stern of the boat in the opposite direction which puts the vessel into a turn.</sub>

<sub>Reverse System

Reverse is achieved by lowering an reverse deflector into the jet stream after it leaves the nozzle. This reverses the direction of the force generated by the jet stream, forward and down, to keep the boat stationary or propel it in the astern direction.</sub>

Intake Section

The intake section has been designed to ensure optimum efficiency across a wide range of boat speeds and pass thrust to boat through installation plate. A intake grill is installed under intake section to prevent big debris from impacting or damaging impeller and guide vane.

Steering parts

The standard steering deflector is a balanced design which can be operated by the normal helm pump hydraulic steering system or an electro-hydraulic steering control system.
