All QSV Pumps - IMPORTANT!
There is no limit on pumping capacity when operating QSV pumps in parallel.
The discharge pressure of your QSV pump may be increased by 100 psig (6.9
barg) by connecting another pump in series ahead of the QSV pump. Care
must be taken, however, so that the inlet pressure to any QSV pump does not
exceed the 100 psig (6.9 barg) maximum inlet pressure rating.
There must be adequate flow through the pump at all times to prevent exces-
sive heat build-up.
