Oil Sealed Pumps
High vacuum pumps are used when the final absolute pressure required is very low.
These pumps may run continuously connected to closed containers to be emptied, and may not run continuously at length, at atmospheric pressure. The exhaust from these pumps is not filtered, thus, special purifiers are available for fumes.
The operating principle of the high vacuum pumps is like the lubricated rotary vane vacuum pumps one. However, in this case, the stator is immersed in the lubrification oil which has also the function of sealing the air loss. The pressure levels reached by this type of pumps are higher than any other rotary vane pump. These pumps are equipped with a gas ballast system to avoid the condensation of the water vapor.
The high vacuum pumps can be made of a single rotor-stator group (single stage) or they can be made of two rotor-stator groups connected in series, so the first group drain is connected to the second group intake system (double stage).
RD 2D
Nominal Capacity: 1.2 CFM
RD 2D double stage high vacuum pump is specifically designed for refrigeration and conditioning applications. The double stage construction provides optimal final pressure. The industrial monobloc design with the rotor directly assembled on the motor shaft and the use of light-weight alloys mean that the RD 2D pump is of limited size and weight and can be fitted into a limited space, provided there is good ventilation or that it is assembled on mobile equipment.
