Trap Plate pumps are old style pumps that employ a trap plate and offset rotating rotor. The volumetric throughput of this style is limited in product offering, but this type pump has a good affinity to work through a great deal of end user abuse and will consistently work for very long periods of time without need for repair or rebuild. We have received a number of calls for service or parts for a pump consistently in use with ages in excess of 50 years. Our brands have been around for a long time. PressoVac, HyVac 1, MegaVac.

We also have a complete line of Single Stage (10^-2 Torr) that are your basic rotary vane oil sealed pumps from 80 liters per minute to 500 Liter per minute. These go by the HyVac naming convention and are called HyVac 7s, HyVac 14s, HyVac 28s, HyVac 45s.

Our FluoroVac Line was developed for use in refrigeration recovery and reclamation applications. These pumps are generally used to capture refrigerants having vapor pressures lower than 1 torr. We have 4 product offerings in this group and are generally of interest to OEM developers of refrigerant recovery or reclamation systems.
