Mechanical Booster Pumps (technical information from ULVAC website)
PMB-B/C Series Mechanical Booster Pumps
By using them together with dry pumps, oil rotary vacuum pumps or water-sealed pumps, mechanical booster pumps can increase the evacuation speed in the 1 kPa to 0.1 Pa range, where rough pump evacuation speed drops. The models in the PRC-A Series are the successors to ULVAC's PMB-006C(M), and PMB-012C(M) models. Like the PMB-C(M) Series, they are Roots pumps designed for general-purpose applications, as well as semiconductor and LC manufacturing processes that require a highly clean atmosphere inside and outside the pump. The PMB-C Series is ideal for general-purpose applications and clean applications. The PMB-B Series is ideal for large-capacity evacuation, such as for heat treatment furnaces and melting furnaces.
No lubrication oil in casing chamber, enabling stable performance for water vapor or solvent vapor.
Major components are Tufram -processed, for high surface hardness and outstanding corrosion resistance. Tufram -processed components reduce damage and corrosion inside pump. (Tufram process is used on PRC-A Series and PMB-C(M) Series.)
* PMB-CM/PRC-A (effective at achieving faster evacuation) can be started at same time as rough pump driven by atmospheric pressure, enabling faster evacuation than standard type.
* Evacuation direction can be selected (PMB-024C(M), 040B, 060B).
Vertical or horizontal evacuation direction can be selected, for more compact systems with greater design freedom.

This catalog uses SI measurement units. Conversion to non-SI units is as follows :
Final pressure : 4.0 x 10-1 Pa = 3.0 x 10-3 torr
Pressure: 0.05/0.1/0.2/0.3 MPa = 0.5/1/2/3 kgf/cm2
With optional large-capacity motor, the intake pressure and pressure difference can be increased.
Measured by Pirani vacuum gauge (standard auxiliary pump and oil).
4.0 x 10-2 Pa with MacLeod vacuum gauge
For PMB-024CM, set the repeated evacuation time for air/vacuum ( 655 Pa) to no more than 5 minutes, and the interval to the next evacuation process to at least 5 minutes.
200 VAC 50/60 Hz; 200 VAC 60 Hz; 3-phase
Pump oil types other than the standard type are available. Contact ULVAC.

PRC Series models are not available as explosion-proof types or increased safety types.
