Rotary-claw type pumps are ideally suited to large scale VRTM processes, combining exceptional toughness, high flow rates and low output noise.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, will 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-claw type 80m³ vacuum pump
Vacuum levels down to 40 mbar absolute
Highly reliable and relatively quiet
Very high flow rate ideally suited for multiple mould operation
Replaceable cartridge filter to prevent dust and fibre entering the vacuum pump
Long service intervals
Standard vacuum pump is three phase 415 volt supply, rated output 1300 litres/min
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
Hours-Run Meter
Electronic counter to record the total pump use in hours
Allows accurate planning of service intervals
Absolute Vacuum Gauge
Digital display to provide readout of vacuum level from atmospheric pressure down to zero mbar
Large Reservoir
200 litre vacuum reservoir
Includes six vacuum take-offs (three fitted with regulators)
Regulators provide constant downstream vacuum independent of upstream variations
