OVERVIEW :
It is a metal diaphragm twin-headed vacuum pump. As all the pumps we
produce, this model is perfectly clean and dry. Materials exposed to the vacuum
environment are 316L stainless steel (except four small springs in berylium
bronze and the metal that you choose for the static metallic seals). Safety is
reinforced by a double containment barrier which internal pressure is
permanently monitored by an electrical contact manometer.
OPERATING PRINCIPAL :
Each pumping head is made up of a cylinder head diaphragm sub-assembly.
Suction and discharge of the gas result of the alternative motion of each
diaphragm and valves. Both chest of valves include possibly a by-pass for high
pressures. The motor power is transmitted to the metal diaphragms by one
crankshaft, then by an intermediary mechanism.
APPLICATIONS :
These pumps are used all over the world to circulate all kind of gases
which can be aggressive, inert, toxic or radioactive (for instance, corrosive
gases like UF6, ClF3 in uranium enrichment industry). This pump is also used as
a backing pump for our model 15 m3/h to achieve 5.10-3 mbar from atmospheric
pressure.
BENEFITS :
o Completely dry and fluid tight vacuum pump
o Safety, reliability
o Low running and maintenance cost (no liquid nitrogen, no oil, long service
life)
o Low noise and vibration level
