Description
DURAN® water jet pump with non-return valve is a laboratory vacuum device that generates reduced pressure by directing water through an internal nozzle. Water consumption is rated at 300 l/h; higher supply pressure or flow increases the attainable vacuum. Constructed from borosilicate glass 3.3, the pump includes an integrated non-return valve that prevents back-flow of water into the evacuated system. Typical applications comprise aspiration of liquids and vapours, vacuum filtration, filtration under reduced pressure and general vacuum generation for safe laboratory work. Connection to a standard water-based supply system is possible, enabling pressure-driven filtration without additional pumps. This unit from manufacturer Duran/DWK Life Sciences offers a compact, chemically resistant solution for routine filtration and degassing tasks. Net weight is 0,054 kg, facilitating easy mounting on a laboratory stand or bench. The all-glass construction ensures transparency for visual monitoring of operation and simplifies cleaning between uses.

Questions about DURAN® Water Jet Pump, with non-return valve
What is this article?
DURAN® Water Jet Pump, with non-return valve is the article on this page. Luminix Health distributes DWK Life Sciences 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.
