A good starting point is the series number.
A normal capacity in cubic feet / minute or CMH at inlet condition is designated by number that follows DC-series. Actual capacity of given pump in service depends , of course , on several factors.
One is the vacuum required. Depending on the vacuum range in which it will be used most, a VACCOMP Type DC vacuum pump can be furnished with specialized characteristics.
Configuration can be idealized for a particular range.
