6 – Foreline Pumps Description
TPS-mobile can be equipped both with a dry pump (scroll type) or
with an oil sealed Rotary Vane Pump. TPS-mobile versions equipped
with a scroll pump are free of contaminating agents and therefore are
suitable for applications requiring “clean” vacuum.
TPS-mobile versions equipped with scroll pumps are: 9698416,
9698412, 9698418, 9698402, 9698401, 9698404, 9698406, 9698422,
9698423, 9698427, 9698428, 9698429, 9698432 and 9698433.
The scroll pump principle of operation is described here following.
Scroll pump creates vacuum using a simple dual scroll mechanism in
which one of the nested scrolls orbits about the other, creating
moving zones of captured gas.
Gas enters the scroll set at the perimeter and is displaced and
compressed toward the center hub where it is exhausted.
