Mid Series Venturi Vacuum Pump - VP50

The all pneumatic VP50 Series are air pilot controlled venturi vacuum pumps that feature an integral check valve and air pilot controlled blow-off for rapid part release or vacuum line clean out. Using air pilot control, VP50 Series pumps generate vacuum only when needed, minimizing compressed air consumption.

  • All pneumatic - no electric power required
  • Precise control - individual pneumatic connections let you control the vacuum and the blow-off duration time
  • Instantaneous vacuum as needed - minimal air consumption
  • Accurate part positioning from positive vacuum and rapid blow-off
  • Easy installation - modular design speeds installation and minimizes assembly

The model number for the VP50 All Pneumatic Pilot Controlled Venturi Vacuum Pumps consists of the base model acronym (VP50) plus three alphanumeric clusters. These clusters designate the vacuum flow and vacuum level, and the final cluster indicating the version of the V50 model. Refer to the chart below for an example of model number VP50-60H-AS. This is a VP50 pump with a maximum vacuum flow of 60, maximum vacuum level of 28"Hg [948mbar], and Air Saver version of the pump. VP50 pump comes standard with a ST4 silencer, there are no further options. Note, part numbers beginning with I- denote a model with G port metric threads.

* The operating pressure of 80 PSI is standard, and the 80 designation does not appear in the part number
