This type of vacuum pump is not adversely affected by air-admittance during the moulding process (‘rough’ vacuum) unlike oil-lubricated pumps which, despite achieving higher levels of vacuum, can vent oil vapour if used in this type of application.
Available as stand-alone pumps or in a range of configurations.
High-output oil-free rotary vane vacuum pumps
Range of rated outputs with maximum vacuum level of 100-150mbar absolute
Fitted with Replaceable cartridge-filter to prevent dust and fibre entering the vacuum pump
Running time approx 4000-8000 hours between service intervals
Available configured to suit single or multi-mould operations
3 Phase Supply Option
Larger (25 and 40³/hr) pumps can be specified for three phase or single phase supply
Simple ON/OFF Control
Start/stop DOL control with motor overload protection
Full Switching Control
Digital display of vacuum level (gauge)
User adjustable digital switching unit to minimise pump operation whilst providing constant vacuum output.
Automatically turns pump ON/OFF between pre-set max/min vacuum level settings.
Control unit with MCB fusing, motor overload protection, and solid-state relay power switching
Absolute Vacuum Gauge
Digital display to provide readout of vacuum level from atmospheric pressure down to zero mbar
Hours-Run Meter
Electronic counter to record the total pump use in hours
Allows accurate planning of service intervals
Small Reservoir
20 litre vacuum reservoir
Includes two vacuum take-offs (one fitted with regulator)
Regulator provide constant downstream vacuum independent of upstream variations
