Harvest Right Premier Industrial Oil Vacuum Pump (110V)

Replacement Industrial Vacuum Pump for Small to Large Freeze Dryers, 110V

The vacuum pump does the critical work in every freeze-drying cycle, pulling the chamber down to the low pressure that lets frozen water sublimate away. A worn or undersized pump slows batches or stops them entirely. The Harvest Right Premier industrial oil pump is built to the specifications of Harvest Right freeze dryers, with an energy-efficient DC motor and industrial-grade design.

This standard Premier pump is rated for Small, Medium and Large Harvest Right freeze dryers. At 52 decibels it runs quietly enough for kitchens and living spaces, so overnight cycles stay unobtrusive.

Key Features & Benefits

• Industrial-grade design — built for the repeated long cycles that freeze drying demands.
• Energy-efficient DC motor — runs on standard 115V, 60 Hz household power.
• Compact 32 lb build — measures 16.3 x 6 x 12.1 in, so it fits beside or under the freeze dryer.
• Matched to Small, Medium and Large freeze dryers — sized to the chamber volume of those Harvest Right models.

Who Should Use the Premier Pump

This pump suits owners of Small, Medium and Large Harvest Right freeze dryers who need a replacement or a spare pump, or who are upgrading from an older standard pump. Keeping a spare also lets homesteads and small producers keep running while a pump is serviced.

Frequently Asked Questions

Which oil should I use?

Use only Harvest Right vacuum pump oil, Robinair Premium High Vacuum Pump Oil or JB Industries Black Gold Vacuum Pump Oil, as Harvest Right specifies. Other oils can affect vacuum performance and pump life. Fill to the level marked on the pump's sight glass.

How often should I change the oil?

Harvest Right recommends changing pump oil every 20 to 30 batches on its Home Pro freeze dryers, which takes about two minutes. Change it sooner if the oil looks cloudy, dark or milky. An oil filter lets you clean and reuse oil between changes.

How does an oil pump differ from an oil-free pump?

An oil pump uses oil to seal and lubricate its internals, so it needs periodic oil changes. Oil-free scroll pumps need no oil changes or routine maintenance but cost more. Both pull the deep vacuum freeze drying requires.

Will this pump fit my freeze dryer?

This pump is rated for Small, Medium and Large Harvest Right freeze dryers. For X-Large freeze dryers, choose the XL Premier pump instead. Contact Harvest Right if you're unsure which pump your model uses.

Why does vacuum matter in freeze drying?

Freeze drying depends on very low pressure so frozen water can sublimate, turning directly from ice to vapor. Without a deep enough vacuum, ice melts instead and the food or material doesn't dry properly. A healthy pump keeps cycles on schedule.
