2.2.1 General
General characteristics of the pumps are defined in Table 1 below. Characteristics shown are displacement, pumping
speed and maximum permitted interface pressures.
Suckback on pump switch off typically 30 mbar ls

(leak tightness 1x10
-6
mbar ls

).
Table 1 - General characteristics
* The XDS pumps can survive an excursion to 1 bar gauge in the exhaust line. However, under normal
operating conditions (with the pump running) the exhaust line pressure should be as close as possible to
atmospheric pressure. If the pump is operated with a raised exhaust line pressure this will accelerate tip
seal wear and lead to a loss of pumping performance.
Ambient temperature:
Operating range 10 °C to 40 °C
Storage range -30 °C to 70 °C
Surface temperature of pump above ambient (when operating at ultimate) typically 45 °C
Maximum humidity (operation) 90%
Altitude up to 2000 m
