Hi Edward,
Yes contact the guy and ask if you realy have two 210 l/s pumps, as I
cannot beleve that.
Nearly impossible. I looked it up in the Leybold and Edwards catalogues.
Pumps of that capacity have a weight of 600 kgs (about 1350 lbs) and the
motor have a power of 15,000 watt. An average mechanical pump have an
average pumping speed of 1 l/s and the electrical power then is about
0.5 BHP.

Best from dirk.
