Vacuum Pump Selection Guide
BOC Edwards provides a wide range of mechanical rotary vane vacuum pumps with pumping speeds up to 56.5 cfm. These pumps
combine high performance with high reliability.
RV Pumps
The RV pumps provide enhanced performance, improved relia-
bility and greater flexibility for a wide range of difficult applications.
The unique RV design features:
-
High performance
-
Continuous high inlet pressure operation with high gas loads
-
Superior water vapor handling capability.
-
Quiet operation (less than 48 dBA)
-
Versatility
-
Dual pumping modes to optimize gas throughput or
ultimate vacuum
-
One motor for 50/60 Hz and 115/230 V operation
-
Enhanced reliability
-
Corrosion-resistant polymer blades
-
Printed gasket technology
-
Unidirectional outer shaft seal
-
Electronic start relay
-
IEC 1010/IP 44/CSA/CE approvals
-
CSA NRTL/C approval on entire pump (conforms to
UL 3101-1)
EM Pumps
Using the direct-drive rotary vane principle, BOC Edwards' EM
rotary vacuum pumps are compact and vibration free. They offer
the following capabilities:
-
Comprehensive range - 0.56 to 19.4 cfm
-
Good ultimate vacuum - down to 7.5 x 10
-5
torr
-
Made from high quality, corrosion-resistant materials
-
Advanced, positive pressure oil lubrication endures reliable
performance even at high gas loads
-
Easy maintenance and service
BOC Edwards incorporates a proven positive pressure oil lubri-
cation system to ensure correct oil lubrication in all duty modes and
to prevent oil starvation at high gas loads. The use of this system
means that oil reservoir levels are less critical.
Medium Size Pumps
BOC Edwards offers a wide range of roughing pumps that
include the medium mechanical rotary pumps (29.7 cfm and 56.5
cfm). These pumps cover a comprehensive range, as well as pro-
vide high ultimate vacuum down to 7.5 x 10
-4
torr, with low noise
levels and vibration levels.
Aspecial feature of the medium EM pumps is their central vac-
uum inlet that allows you to fit a mechanical booster pump with a
minimum overhang, to create an extremely compact combination
pumping system. The medium mechanical rotary pumps are fan
cooled
