Special application( Spec. K, H and Z )
*1 Measured with a Pirani gauge. (Approx. 6.7X10
-2
Pa when measured with a McLeod vacuum gauge.)
*2 The pump of this type, PVD-180B and 360B have following specific features in comparison with the
standard type, PVD-180, -360.
1) The pump [Type: PVD-180B or 360B] has a solenoid valve called Vac. Lock Valve (means Anti
Suck Back), when the pump stops the valve shuts off incoming oil and air and keeps a good vacuum
for a long period of time.
2)While the pump is running, the valve is open and appropriate amount of oil is supplied into the cylinder.
Please note the contents of "Ⅱ-4 Electrical connections" and "Ⅲ Operation" for the running of PVD-
180B or PVD-360B.
Recommended type of oil:
(1) ULVOIL R-72 (standard oil)
(2) ULVOIL R-42 (For cold district in winter. In the case of ambient temperature 4~10℃)
