Welcome to millMAX Pump Training for Taggart China 10 Offices Worldwide Problems With Conventional Slurry Pumps Conventional Pump Design Conventional flow recirculation based on clearance versus pump speed Solids Concentration is Highestat Impeller Shrouds Suction-Side Recirculation Wide Gap at the Front and Back Grinding of Solids between the Impeller and Suction Liner or Throat Bush Uneven Parts Replacement Cycles Suction Side Liners and Impellers wear 2 to 3 times Faster than Pump Cases. Importance of Cyclone Performance Summary of Conventional Pump Problems Slurry recirculation on the suction side Grinding of solids between the impeller and suction liner Reduced hydraulic efficiency (Er) Reduced (cyclone) performance over time High power consumption Low parts wear life Unequal maintenance cycles Unscheduled shutdowns Ball chips or tramp jams the impeller front or back side Inability to increase capacity using existing motors and drives millMAX Design Concept millMAX Design 3x2 thru 14x12 Incorporates a backliner Solid volute case Wear Ring adjustment thru the casing Water flush, centrifugal seal and vacuum-pressure gland millMAX Large Pump Design 16x14 thru 28x26 Incorporates a suction liner Casing with suction plate Wear ring adjustment thru the suction liner Water flush gland Krebs millMAX Pump Solving the Recirculation Problem Patented “Hybrid” Sealing System Urethane carrier provides a seal against the intrusion of slurry. Long wearing high chrome iron wear ring seals against impeller. 4-6 jacking screws are used to adjust the wear ring forward as the pump is running. Krebs millMAX Pump Running Clearance Adjustment Setting Clearances While the pump is running. Without disconnecting the drive. Without moving the impeller and shaft assembly. Without disturbing guards or v-belt drive. Impeller High Radial Vanes Clears large solids. Prevents solids from being crushed. Reduces differential pressure at the eye of the impeller. Adjustable W
