Direct-Drive, Rotary Vane Vacuum Pumps

Direct-Drive, Rotary Vane Vacuum Pumps

Wide range of free-air capacities to match specific applications
Positive pressure oil system ensures proper lubrication and prevents oil starvation at high gas loads.
Fast acting inlet valve protects internal components against oil and air contamination if the pump stops while under vacuum.
Gas ballast valve limits internal condensation; lets you use pump when condensable vapors are present.

No need to purchase both single- and dual-stage pumps! Dual-mode pumps offer a choice of high-vacuum (HV) mode or high-throughput (HT) mode in one pump. Pumps also feature three-position gas ballast control. Set the pump to HV mode with gas ballast off for use with electron microscopes or mass spectrometers; set it to HT mode with gas ballast fully open for use with gel dryers, vacuum ovens, or rotary evaporators. What�s included: vacuum oil. Pumps do not include a power cord.

Power cord and plug are included with the pump.
Standard Vacuum Pumps
Use standard pumps for general vacuum applications. Pumps are available in single or dual stage models�use dual-stage pumps to achieve higher vacuum. All standard models include O-ring, centering ring, cable gland, spare seals for oil drain, filter plugs, and vacuum oil (1 liter). Pumps do not include line cord or plug; see page 214 for cord/plug assemblies. Order optional oil mist filter and return kit to reduce maintenance time separately.
Dual-Mode Vacuum Pumps
No need to purchase both single- and dual-stage pumps! Dual-mode pumps offer a choice of high-vacuum (HV) mode or high-throughput (HT) mode in one pump. Pumps also feature three position gas ballast control. Set the pump to HV mode with gas ballast off for uses with electron microscopes or mass spectrometers; set it to HT mode with gas ballast fully open for uses with gel dryers, vacuum ovens, or rotary evaporators. Dual-mode pumps include vacuum oil and 6-ft line cord. To reduce maintenance time, order optional oil mist filter and return kit separately.
Accessories
Service kits include springs, seals, gaskets, O-rings, filters, valves, and washers. Replace every 15,000 hrs. Oil mist filter and return kit directs oil back into your pump reducing oil changes and maintenance time.
