Technical Brief:
How Vacuum Pumps Work
Operating / Installation Instructions:
VP01QRBV Solenoid Controlled Venturi Vacuum
Pump
Proudly Made In The USA
Opera ng and Installa on Instruc ons:
1.
Mount pump. Pump has two through holes that accept 4-40
(M3) screws (screws not supplied). Pump works in any
orienta on.
2.
A ach air line to supply port. A ach vacuum line to vacuum
port (when not directly a aching vacuum cup). Use 1/4”
tubing [6mm] (minimum) for vacuum and air supply ports.
3.
Confirm proper solenoid voltage located on the side of the
solenoid valve.
4.
Connect posi ve and nega ve power supplies (24 VDC or 110 VAC). Check wiring schema c to right to
ensure proper connec on. Black lead -24 V DC, red lead +24 V DC). Pump is also available with an
op onal 3-pin male M8 connector.
5.
Turn on compressed air and regulate to specified pressure (80 PSI standard, -60 models 60 PSI). Set
regulator while pump is opera ng.
6.
Energize vacuum valve to create vacuum.
7.
De-energize valve to turn off vacuum
8.
Energize vacuum valve to create vacuum.
9.
De-energize valve to turn off vacuum
Principles of Opera on
Compressed air is supplied to both normally closed (N.C.)
solenoid valves simultaneously. To create vacuum, energize the
first (vacuum) solenoid valve to allow the compressed air to
flow to the miniature venturi cartridge resul ng in
instantaneous vacuum.
To release the part, de-energize the vacuum solenoid while
energizing the blow-off solenoid. Because the blow-off air is at
line pressure, a very powerful blow-off will be created.
Vacuum is produced in a venturi cartridge 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 inlet port, located between the nozzle and
diffuser. T e nozzle and diffuser combine to create a vacuum
h
cartridge. The precise fit of the nozzle to the diffuser is cri cal
to the pump func oning properly.
