Our pumps have a following designations:
Example)
WOVP - 0060 - N

③ |
①
This indicates the type of pump.
WOVP
: Oil Sealed Rotory Vane Vacuum Pump
WVS
: Sliding Vane Dry Vacuum Pump
WBS
: Sliding Vane Dry Combined Pump
(
Vacuum and Pressure Function )
②
This indicates the effective exhaust speed.
0060
: 600ℓ/min
0320
: 3200ℓ/min
This
is actual effective pumping speed at 60㎐.
At 50㎐, a pumping
speed decreases 1.2 times.
③
This shows the classification of High
vacuum and Low vacuum type.
N
: 0.5 mbar
L
: 20 mbar
