Product Comparison

This Premier Oil Vacuum Pump vs the Standard Oil Vacuum Pump

Oil Changes

This 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 up to 25 or more batches. You simply won’t need to filter and top up the oil until you have run 20 or more batches. Whereas, the oil in the Standard Pump needs to be filtered and topped up every 4 or 5 batches (when using the new 3/8 inch vacuum hose).

You should only replace the oil in the premier pump with Robinair Premium High Vacuum Pump Oil or with JB Industries Black Gold Vacuum Pump Oil. Do not use Dairyland vacuum pump oil or Harvest Right vacuum pump oil. Both of these oils are great for Harvest Right's standard oil vacuum pumps. However, these oils will not work in the Premier (Industrial) Vacuum Pump because they have detergents in them.

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 relatively small: 0.05 Pascal for the Premier Pump and 0.08 Pascal for the Standard Pump. Whereas, under warm conditions, the difference is much greater: 0.05 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.
