communication with Andair is frustratingly hit or miss... when you actually get a response it is prompt and efficient; unfortunately, most emails go dark without acknowledgment or response...
as a followup: i received a replacement pump that performs well out of specification both on the factory test card and in my installation... it pumps a at higher pressure than specified with a higher maximum pressure, likely just fine, but well over spec...
closed flow @ 42 psi and 30gph @ 32 psi
versus the spec of
closed flow max 30-33 psi and 16 gph @ 27-30psi
in reply from Andiair... the higher pressure allows a greater safety margin and most injector bodies can handle 80psi with a working pressure of 30-40.
heads up on the new pumps... mine draws 8 amps up from the previous spec of a max of 6
