The oil free scroll vacuum pump is available for any size Harvest Right freeze dryer. These pumps are quiet, fast, and easy to use.

Over time as the scroll vacuum pump may wear and not pull as good of a vacuum, you can get this rebuild kit for $185 for the standard size oil free scroll pump (for small, medium, and large freeze dryers), or $199 for the extra large size oil free scroll pump (used on extra large freeze dryers).

The scroll vacuum pump rebuild kit consists of bearings, seals, etc. - all the wear parts that need to be serviced -and you do the rebuild when needed, which typically is every 1-3 years depending on the pump's workload in your usage. This kit requires you to have a moderate level of shop experience and knowledge. You may have to fabricate a tool. 

Please call to discuss before ordering, unless you have a high degree of confidence that you are going to be able to do the pump rebuild successfully.

Here is an excellent rebuild video for the pump that goes through every step of the process in detail.
