By what goes through the pump. Clean and continuous: dry. Clean but budget-driven: oil-sealed. Wet, dirty or carrying condensate: liquid ring, which is almost indifferent to carry-over.

Packaging works at 100–200 mbar. Vacuum drying and distillation need 0.1 mbar or lower. Specifying deeper vacuum than the process needs is one of the most expensive mistakes in a plant.

Pumping speed is how fast a pump moves gas, ultimate pressure is the deepest vacuum it can reach. A pump can have a fine ultimate figure and still take an hour to pump your vessel down.

Usually leaks, the wrong fluid or a blocked filter rather than a worn pump. We measure ultimate pressure, pumping speed, leak rate and power draw before recommending anything.

More than most plants realise, because it is rarely metered. A central system running continuously can be one of the three largest electrical loads on a site, and it is usually oversized.

Yes, most of the pumps that come through our workshops were supplied by somebody else, and that is entirely fine.

It sits on top of a backing pump and multiplies pumping speed in the range where the backing pump has gone slow. A vessel that took forty minutes to evacuate typically comes down to eight.

On liquid ring installations, yes, and it is usually the single biggest saving available: 30–50% less energy than throttling, plus lower sealing water consumption.

A dry claw pump runs about 20,000 hours between major services on a clean duty. An oil-sealed vane pump depends almost entirely on whether the oil is changed and the right grade is used.

Yes, and the report is yours whether or not you buy anything. Leak testing and pipework assessment usually find the problem long before the pump is at fault.
