Variable Vacuum / Flow Venturi Vacuum Pumps - VDF

Developed for extremely dirty and dusty environments such as foundries, refractory and bagging operations, VDF pumps don’t clog, lose suction or require a vacuum filter. Standard VDF pumps are field-adjustable allowing you to regulate the vacuum flow and vacuum level to meet your application requirements. This maximizes energy efficiency by consuming only the compressed air necessary to do the job.

  • Adjustable vacuum level and flow rate:
  • Powerful vacuum up to 25”Hg [847mbar]
  • High flow rates up to 120 SCFM [3398 LPM]
  • Efficient – high performance to air consumption ratio
  • Safe operation: no electricity needed at the pump
  • Reliable – straight-through design, non-clogging

The model number for the VDF Series of Variable Vacuum / Flow Pumps consists of the base model acronym (VDF 250, e.g.) plus three alphanumeric clusters. These clusters designate the optional silencer, optional preset vacuum level the optional body material. Refer to the chart below for an example of model number DF 5-6-TV50/TE50-304. This is a DF 5-6 pump with minimum bore of 0.50" and TV50 and TE50 internal vacuum and exhaust port threads. External vacuum and exhaust port threads are also available. The 304 refers to optional 304 stainless steel body material.
