PVD series is a compact, double-stage rotary vane oil rotary vacuum pump coupled with belt-driven motor.
From the reliability and ease of use over the years, is a small belt-driven oil rotary vacuum pump has gotten used to a lot of customers.
From the low-speed rotation, it performs a quiet and stable exhaust characteristics.
Applications
Vacuum filling and gas exchange
Vacuum adsorption , transport and casting
Vacuum molding
Vacuum drying and freeze drying

Note)This specification uses SI measurement units. Conversion to non-SI units is as follows
6.7 Pa = 5 × 10-2 Torr
*1 PVD-180B and PVD-360B are versions of PVD-180 and PVD-360 with oil backflow prevention mechanisms.
*2 Measured with a Pirani gauge. ( Apprx. 6.7x10-2 Pa when measured with a McLeod vacuum gauge. )
*3 Please indicate the motor type, voltage and frequency requirement when ordering.
As an option, explosion proof types are available. PVD-B series which are with solenoid valves
are not able to select explosion-proof type.
*4 The energy efficiency regulation is not applicable for this motor.
