Harvest Right Freeze Dryer Replacement Pump

 Premier Oil Pump vs Standard Oil Pump

Oil Changes
This new Premier Pump rarely needs to have the oil changed or filtered. The pump has a gas ballast feature that makes it so water does not stay in the oil. Because of this, the oil in the pump will be pristine and clear, even after 30 or more batches. You simply won’t need to change the oil until you have run 20 or more batches. Whereas, the oil in the Standard Vacuum Pump needs to be changed and filtered every 4 or 5 batches (when using the new 3/8 inch vacuum hose). You should only replace the oil in this pump with Robinair Premium High Vacuum Pump Oil (or with JB Industries Black Gold Vacuum Pump Oil). These may be purchased from Harvest Right, Amazon, and other locations. Do not use Dairyland vacuum pump oil in the Premier pump.

Vacuum Pressure
Under cold and hot conditions the Premier Pump will pull a deeper vacuum than the Standard Pump. Under cold conditions the difference is .05 Pascal for the Premier Pump and .08 Pascal for the Standard Pump. Whereas, under warm conditions the difference is much greater: .05 Pascal for the Premier Pump and 2.05 Pascal for the Standard Pump.

Hence, the Premier Pump is especially not affected by warm, ambient conditions. When temperatures rise, it will pull a vacuum far better than the Standard Pump. The Premier Pump is just not affected by outside heat. It pulls the same deep vacuum even when it is in a warm environment.

Noise
The Premier Pump is substantially quieter than the Standard Pump, 52 decibels versus 64 decibels. The Industrial Pump at 52 decibels is about the same as a refrigerator.

Oil Mist Filter
Both pumps come with an oil mist filter. However, the Premier Pump’s oil mist filter allows for no oil spray at all and it will last much longer.

Power Use
The Premier Pump uses less power than the Standard Pump (187 watts versus 218 watts).

Amperage
Under hot conditions at ultimate vacuum pressure the Standard Pump pulls 2.1 amps while the Premier Pump only pulls 1.7 amps. Hence, the Premier Pump is more efficient.

Weight
The Premier Pump is easier to move around as it weighs 5 pounds less than the Standard Pump (32 lbs. versus 37 lbs.)

Life
The Premier Pump is more durable and will last longer than the Standard Pump.
