Lost prime - vacuum filtrate pump
Lost prime - vacuum filtrate pump
(OP)
Vacuum filtrate receiver pump occasionally pumps receiver empty and loses its prime when level control fails. Pump is about 10 feet below bottom of receiver. An old filter manual says that receivers can be fitted with an added connection for centrifugal pumps to prevent loss of prime. However, no details provided. Does anybody know how this would work?

I think one possibility would be by connecting the pump's volute highest point to the filtrate receiver via an automatic priming valve.
