Welch general purpose 2 stage belt driven pumps designed to operate at lower RPM allowing them to run cooler and reach an ultimate vacuum of 1 x 10-4 Torr. Lower speed operation also reduces the wear on the pump components ensuring a longer life. All pumps are equipped with a gas ballast.
Pumps operate on 115V, 60Hz and can be ordered for 230V operation.
Long Service Life due to Low Pump RPM Suited for:
