Click Here Cylindrical Venturi Vacuum Pumps Ideal Applications: • Gas sampling and analysis • Leak testing • Portion/ drip control (suck-back) for dispensing liquids • Liquid transfer • Pick and place for small, non porous parts • Small vessel evacuation • Used as vacuum source for vacuum pencil kit (see page 271) Ultra-Mini Cylindrical Venturi Vacuum Pumps Ultra-Mini J Series: JS-40UM Features/Benefits • High performance - powerful vacuum up to 27"Hg [914mbar] • Lightweight – less than 1 oz. [28.3g] • Compact – 1.25" x .56"OD [31.75mm x 14.22 mm OD] • Input pressure from 5 PSI [0.34BAR] • Fast response – Mounts in-line, and installs close to vacuum point – no delay due to long plumbing lines Ultra-mini pump for drip control in dispensing applications JS-40UM generates 27"Hg and weighs less than 1 oz • Efficient – Minimal air consumption, provides instantaneous vacuum as needed • Safe operation – No electricity needed • Reliable, trouble-free operation ~ No moving parts to wear ~ No flap valves to stick open ~ No maintenance ~ No downtime Standard Pump: The JS-40UM (Ultra-Mini) cylindrical venturi vacuum pump is the smallest complete venturi vacuum pump that Vaccon offers. Incredibly compact and powerful – it measures the size of your finger tip and generates up to 27"Hg [914mbar]. Lightweight, quiet and cool operating, JS-40UM pumps are ideal for confined spaces, where they can be mounted in-line near the point of use for rapid response. The single-stage design allows ingested contaminants to flow through the pump without clogging ensuring continuous operation. Constructed of a single material, with no seals or moving parts, J Series pumps are virtually indestructible. They can be manufactured in a variety of materials, making them ideal for use in adverse operating conditions. J Series pumps provide a constant vacuum flow, rather than a fluctuating flow typically associated with diaphragm pumps. They operate with an instantaneous response in pulsed applications or on a continuous basis. J Series pumps can be powered by alternate media (gases, liquids) etc. For liquid powered pumps please see our JW series on page 183. Pump Options: • Optional Silencer: VCF2-1032M • Choice of operating pressures to meet machine and factory air supply 80 PSI [5.5BAR] standard, 60 PSI [4.0 BAR] optional • G port threads for metric machines – an “I” prefix designates products with metric threads • For chemical compatibility requirements, high temperature, food, medical and caustic applications, custom materials are available including stainless ™ steel, PEEK, Delrin, Teflon,™ PVC. Principles of Operation: Vacuum is produced by forcing compressed air through a limiting orifice (nozzle). As the air exits the orifice it expands, increasing in velocity to supersonic speed before entering the venturi section (diffuser). This creates a vacuum at the vacuum inlet port located between the nozzle and diffuser. Air Supply Exhaust Vacuum Eliminate the Guesswork: Contact Us! Vacuum technology isn’t an exact science.
