Vaccon VPI-90H Operating Instructions
Installa on Instruc ons:
Vaccon’s VPI-90H in-line venturi vacuum pump features the air supply port and
vacuum port on the same axis. Unlike standard venturi vacuum pumps where
the vacuum port is 90 degrees from the supply port, the VPI-90H’s can be
a ached ver cally to a robo c end of arm tool in a single or densely populated
array to accommodate any size, shape and weight of product being handled.
1.
Install in-line vacuum pump to your moun ng hardware, end-of-arm-tool, extrusion, etc.. The op onal
panel mount nut can be used to secure the pump to a panel. The exhaust port has a 5/8-18 UNF male
thread. The panel through hole should be at least ⅞” [21 mm].
2.
A ach air line to air supply port. A ach vacuum line to vacuum port (when not directly a aching a
vacuum cup to the port). See chart below for minimum recommended sizes.

How Vacuum Pumps Work
Operating Instructions:
VPI-90H
Inline Venturi Pump
Principles of Opera on
Vacuum is produced by forcing compressed air through a
limi ng orifice (nozzle). As the air exits the orifice it expands,
increasing in velocity to supersonic speed before entering
the venturi sec on (diffuser). This creates a vacuum at the
vacuum inlet port located between the nozzle and diffuser.
The nozzle and diffuser combine to create a venturi vacuum
cartridge. The precise fit of the nozzle to the diffuser is
cri cal to the pump func oning properly.
