PERISTALTIC PUMP

11Peristaltic PumpUses positive displacementConsists of hose and rotorWork within ranges of:Flow rate: .2 200 gpmHead(Pressure): 10 250 psiHorsepower: 0.125 40 hp

12Chopper PumpsCentrifugal PumpMultiple cutting surface, reduces solids size, high viscosity and less power More feed rate than peristalticLow Maintenance
