Beschrijving
Water jet pump with non-return valve and nut is a laboratory vacuum accessory built from nickel-plated brass for aspiration and filtration setups. The integrated non-return valve helps limit backflow of water into the connected apparatus when the water supply is interrupted, protecting samples and glassware. A 3/4'' union nut supports secure connection to a suitable water outlet. This water jet pump from manufacturer Witeg is designed for routine laboratory vacuum generation using a water stream, such as vacuum filtration, degassing, or simple aspiration tasks. Nickel-plated brass construction offers durability under typical wet-lab conditions. Net weight is 0,3 kg. Compact and ready to install, it suits teaching labs, quality-control benches, and research workplaces that need a straightforward water-driven vacuum source without electrical pumps. Supplied as one piece for direct integration into existing water-line vacuum arrangements.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Water jet pump with check valve and nut
What is this article?
Water jet pump with check valve and nut is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labmateriaal.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
