MODEL: PMB-D

Mechanical Booster Pump

The Model:PMB Ver. D is a wide use mechanical booster pump with multiple voltage motor (high efficiency). It is possible to run with air-cooled depending on use condition. And surface treatment and atmospheric operation type are selectable as option.

Features

Possible to run with air-cooled depending on use condition. Continuous operation under 200Pa. Pumping time to reach 200Pa needs to be within 10 minutes.
Possible to select multiple voltage motor (either 200V class or multiple voltage) Compatible with universal motor and optional explosion proof motor can be equipped. Compatible with high efficiency regulation (IE2/GB3/EPAct).
Excellent corrosion resistance surface treatment (Optional: T type) High surface hardness and excellent corrosion resistance. The surfaces of all main parts have undergone anodic oxide coating to provide excellent corrosion resistance and surface rigidity. This can restrain scratch and corrosion inside of the pump.
Atmospheric pressure start type effective for pumping time shortening (option: inverter) Because the pump can start at the same time of roughing pump, pumping time can be shorter comparing with standard type.
International standard for western market (Compliant with CE and cTUVus)

Applications

Evaporation, sputtering, ion plating
Vacuum drying, freeze drying, vacuum degassing,Analytical instruments, leak test system
Gas exchange, filling, vacuum insulating,Heat treatment, melting furnace
Other various kinds of vacuum system

Note)This specification uses SI measurement units. Conversion to non-SI units is as follows :
　　4.0 x 10^-1Pa = 3.0 × 10^-3 Torr
*1　Standard model are without surface treatment (Anodic oxidation coatings).
　　Optionaly, with surface treatment model is able to select.
*2　Measured by Pirani vacuum gauge using a standard backing pump and standard vacuum oil.
　　( Apprx. 4.0×10^-2 Pa when measured with a McLeod vacuum gauge. )
*3　Only PMB100D is able to choose the motor of 200V class or Multiple voltage.
　　Multi-voltage selection for explosion-proof motor is not available.
*4　Oil for Air-cooled specifications is SMR-100. Oil option : Optionaly, Mineral oil (SMR-100),
　　Fluorine oil (J25F) type is able to select.
*5　By the selection of inverter mounting model, the operation of entire pressure range will be capable.
　　When ordering the inverter specifications, Specify Air-cooled or Water-cooled specifications.
　　Air-cooled operation is not possible to drive with a water-cooled inverter.
　　For PMB600D, 1200D and 2400D, continuous operation more than 1 hour at pressure range of
　　300 Pa to 4,000 Pa may cause damage to the pump.
　　Select water cooling type in case to use in such condition.
*6　Use in an environment where there is no condensation.
