Northvale Korting or NK provide jet or ejector equipment which operate on ejector and jet pump principle with no moving parts which can be used to pump, mix, heat, cool or produce a vacuum using a high pressure/velocity motive fluid to entrain a lower pressure suction fluid. NK products are steam jet ejector, liquid jet solid eductor, liquid jet mixing educator liquid jet eductor, thermo- compressor, …etc., norval non return valve,
An ejector comprises three key parts – nozzle, diffuser and the body as per this diagram of a typical Venturi fluid jet product.
The driving fluid or motive (steam, pressurised liquid or air) passes through the nozzle of the ejector, converting the pressure energy into a jet. The result of this is that the fluid at the front of the jet is displaced, producing an area of low pressure at the exit of the nozzle.
Replacement fluid sucked in via the branch inlet of the ejector, creating suction flow. The motive – steam, pressurised liquid or air – and the sucked in fluid are mixed as they move through the ejector’s diffuser. The velocity energy of this newly-mixed fluid converts to pressure energy so that the fluid is discharged from the ejector with a back-pressure that is stronger than the suction pressure.
Both the motive and the suction fluid must be compatible and the two coming together allow one ejector to perform two operations, for example pumping and mixing.
Fluid jet products from Northvale Korting are available as individual items or packaged modules with other relevant products such as control valves and pumps.
