Inquiry (采购产品): Filtration operation We are trying to determine the best pressure to run our yardney filter system. The pump pressure with all valves wide open is 18 psi. When the pressure reaches 20 psi we clean the bag, anything greater than that and we have to wrestle with the bag to get it out of the filter container. Does the gate valve have to be rstricted on the discharge side of the pump. We seem to be going through the pump seals yearly. **** Hidden Message ***** charles philpot NE 68506 USA Company: Bryan Hospital E-mail: ccfphilpot@neb.rr.com **** Hidden Message ***** ccfphilpot@neb.rr.com
