Solinst 407 Bladder Pump Configuration:1.0" Stainless Steel x 2ft - 316 SS Balls 5" LCD and capacitive touchThe Solinst 407 Mk2 Bladder Pump is a pneumatically driven groundwater sampling pump built around a flexible Santoprene bladder inside a rigid stainless steel or PVC body. Compressed air or nitrogen from a surface control unit pressurizes the space between the bladder and the housing, collapsing the bladder and forcing the water inside it up through a check valve to the discharge line; venting the drive pressure lets the bladder re expand and refill
