Diaphragm pump use with PK1A kit

[killick]

Will the PK1A kit work with a 3GPM diaphragm pump capable of generating 70PSI ?

Thanks for asking but NO!  The CSV does not work with any kind of positive displacement pump.  It needs to have a centrifugal impeller to work with a CSV.  But positive displacement pumps are rare in the domestic water industry.
