Description
Standard Diode Pumps
Standard Diode Pumps use two titanium cathodes in each pumping element. They are the pump of choice for most applications for their long life, reliability and high speed per unit . These pumps are not recommended when significant amounts of hydrogen or noble gases are to be pumped or where frequent high-starting loads are encountered.

* Pumping Speed Ratings for Ion Pumps
Some pumps in this table have two pumping speeds shown, i.e., 150/100. The lower number is observed when the measurement standard established by the American Vacuum Society (AVS) is followed. The higher number is observed when the same pump is measured under optimum pumping speed conditions. Some manufacturers use the optimum pumping speed, only reporting this higher number. Both ratings are provided here to allow the customer to make an informed choice.
Notice
Due to the current shortage in availability of tantalum material, and delivery of noble diode pumps are subject to change without notice.
1 All flanges ConFlat compatible except 1,000 l/sec pumps.
2 Heaters are model IH-100 Calrod heaters which fit into matching interior heater wells in most pumps.
3 IH signifies interior heater well available as option.
4 DE specifies a double-ended option.
5 No bakeout heaters available for this pump.
6 Larger pumps available on special order.
