Ultra Mini J Series Venturi Vacuum Pump

  • JS-40UM J-series cylindrical venturi vacuum 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.

The JS-40UM pump is used in the Vacuum Pencil KIt for benchtop pick and place operations of small objects.

The JS-40UM pumps are available in a pink color to support breast cancer research. For more details, click hereTo order a pink J series pump add “pink” in the Comments box at checkout.
