Harvest Right Premier Industrial Oil Vacuum Pump 110V

Upgrade or replace the vacuum pump on a compatible Harvest Right freeze dryer with the Harvest Right Premier Industrial Oil Vacuum Pump. Designed specifically for Small, Medium, and Large Harvest Right freeze dryers, the Premier Pump combines deeper vacuum performance, quieter operation, lower power consumption, and significantly reduced oil maintenance compared with Harvest Right's older Standard Oil Pump.

A gas ballast system helps prevent water from remaining suspended in the pump oil, allowing the oil to stay cleaner through repeated freeze drying cycles. For frequent freeze dryer owners, that means less time spent draining and filtering oil and more time processing batches.

• Less Oil Maintenance: Run 20 or More Batches Between Oil Changes
• Quiet 52 dB Operation: Substantially Quieter Than the Standard Pump
• Deep Vacuum Performance: Maintains Strong Vacuum Even in Warm Conditions
• Lower Power Consumption: Efficient DC Motor Uses Approximately 187 Watts

Industrial Grade Vacuum Performance

The Premier Pump is engineered to maintain a strong vacuum under both cool and warm ambient conditions.

According to Harvest Right's comparison data, the Premier Pump can reach approximately 0.05 Pascal under both cold and warm conditions. This is particularly valuable in warmer operating environments, where the older Standard Pump's vacuum performance can decline more substantially.

Consistent vacuum performance is critical to the sublimation process that makes freeze drying possible, making the vacuum pump one of the most important components in the entire system.

Far Less Oil Maintenance

One of the biggest advantages of the Premier Pump is its reduced oil maintenance requirement.

Its integrated gas ballast feature helps prevent water from remaining in the oil, allowing the pump oil to remain clearer for longer periods. Harvest Right states that users may run 20 or more batches before an oil change is required, with oil often remaining clear even after 30 or more batches.

By comparison, Harvest Right's Standard Vacuum Pump may require oil changing or filtration every 4 to 5 batches when used with the newer 3/8 inch vacuum hose.

Actual maintenance frequency should still be based on oil condition and pump performance.

Quiet 52 dB Operation

At approximately 52 decibels, the Premier Pump is substantially quieter than Harvest Right's older Standard Pump, which is rated around 64 dB.

Harvest Right compares the Premier Pump's operating sound level to approximately that of a refrigerator.

For home kitchens, utility rooms, workshops, homesteads, and other spaces where a freeze dryer may operate for extended periods, the reduction in pump noise can make a meaningful difference.

More Energy Efficient

The Premier Pump uses a DC motor engineered for efficient operation.

Harvest Right rates the Premier Pump at approximately 187 watts, compared with approximately 218 watts for the Standard Pump.

At ultimate vacuum under hot operating conditions, the Premier Pump draws approximately 1.7 amps, while the Standard Pump draws approximately 2.1 amps.

The result is a vacuum pump designed to deliver stronger performance while consuming less electricity.

Improved Performance in Warm Environments

Ambient temperature can affect vacuum pump performance, particularly during long freeze drying cycles.

Harvest Right reports approximately 0.05 Pascal for the Premier Pump under both cold and warm conditions, compared with approximately 0.08 Pascal for the Standard Pump under cold conditions and approximately 2.05 Pascal under warm conditions.

The Premier Pump's ability to maintain deep vacuum performance as ambient temperatures increase makes it particularly useful for freeze dryers operating in warmer rooms or during seasonal temperature changes.

Improved Oil Mist Control

The Premier Pump includes an oil mist filter designed to prevent oil spray during operation.

While both Harvest Right's Standard and Premier pumps incorporate oil mist filtration, Harvest Right states that the Premier Pump's system prevents oil spray and offers a longer filter service life.

This helps create a cleaner operating environment around the freeze dryer and vacuum pump.

Compact 32 lb Design

Despite its industrial grade construction, the Premier Pump weighs approximately 32 lbs and measures only 16.3 x 6 x 12.1 inches.

It is approximately five pounds lighter than Harvest Right's older 37 lb Standard Pump, making it somewhat easier to position, remove, or relocate when servicing your freeze drying system.

Approved Vacuum Pump Oils

Harvest Right specifies the following oils for this Premier Pump: Robinair Premium High Vacuum Pump Oil and JB Industries Black Gold Vacuum Pump Oil.

Do not use Dairyland vacuum pump oil in the Premier Pump.

Using the appropriate high vacuum oil is important for maintaining vacuum performance and protecting the pump over its operating life.

Compatibility

This model is designed for use with Harvest Right Small Freeze Dryers, Harvest Right Medium Freeze Dryers, and Harvest Right Large Freeze Dryers.

It is not intended for Harvest Right X Large freeze dryers.

Confirm your freeze dryer model before purchasing a replacement or upgraded vacuum pump.

Premier Pump vs Standard Pump

Compared with Harvest Right's older Standard Oil Pump, the Premier Pump provides several meaningful improvements: longer intervals between oil maintenance, gas ballast technology for improved moisture management, approximately 52 dB operation versus 64 dB, approximately 187 watt power consumption versus 218 watts, approximately 1.7 amp draw versus 2.1 amps under hot ultimate vacuum conditions, better vacuum performance in warm environments, improved oil mist control, five pounds less weight, and improved long term durability.

For owners who regularly operate their freeze dryer, these improvements can reduce maintenance while making the overall freeze drying system quieter and more convenient to operate.

Recommended Use Practices

• Confirm your freeze dryer is a compatible Small, Medium, or Large model before ordering.
• Use only Harvest Right's approved oils for this pump.
• Do not use Dairyland vacuum pump oil in this pump.
• Connect the vacuum hose securely and leave the pump switch in the ON position per Harvest Right's normal operating procedure.
• Monitor oil clarity periodically even though maintenance intervals are extended.
• Keep the pump in a clean, ventilated area near the freeze dryer.
• Disconnect power before performing any pump maintenance.
