Pump selection

I am trying to find a suitable pump for a rather complex application. The pump needs to be self priming as it has a lift of 14 feet. At 100 GPM I expect the total head to be 150 feet. It needs to handle solids atleast 1/4 inch size, the vapor pressure of the pump liquid is about 2 psig at 80 F which really cuts down on the NPSH. And on top of it it would handle a VOC subject to NESHAP requirements- meaning sealless or double seal pumps. I have already rejected diaphragm type pump because of pulsations. Any suggestions, generic or otherwise ? Received on Wed Dec 01 15:09:00 2004
