Description
Water jet pump polypropylene with non-return valve is a compact laboratory vacuum source that operates on the water-jet principle for filtration, aspiration and other moderate-vacuum tasks. Manufactured from polypropylene, the unit includes an integrated non-return valve and a detachable vacuum connection with GL 14 thread for flexible setup and straightforward maintenance. It is suitable for continuous service temperatures up to 80 °C and combines very low water consumption of 190 l/h at 3,5 bar flow pressure with a constant ultimate pressure of 16 mbar. Suction capacity reaches approximately 400 l of air per hour, supporting reliable everyday vacuum generation without an electric pump. This water jet pump from manufacturer Marienfeld offers chemical resistance and long service life under typical laboratory water conditions. The non-return valve helps protect the water line if supply pressure drops, while the screw-off vacuum port simplifies connection to tubing and apparatus. Ideal for educational laboratories, routine filtration setups and applications where a simple, water-driven vacuum source is preferred for consistent performance and economical water use in daily lab workflows.

Questions about Water jet filter pumps,
What is this article?
Water jet filter pumps, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
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.
