REGENERATIVE TURBINE PROCESS PUMPS FOR LOW FLOW, HIGH PRESSURE APPLICATIONS Optimal Hydraulic Coverage “APCO-CHEM” Turbine Pumps Specific speed (NS)1 can be thought of as a hydraulic index number indicating a specific type of pump best suited for a particular application. The Hydraulic Institute lists a range of NS from 500 through 20,000 for centrifugal pumps starting at a straight radial impeller and progressing through an axial-flow design.2 But, what about NS’s below 500? This is where the unique APCO-CHEM regenerative turbine can best serve those special pumping applications. Consider the...

REGENERATIVE TURBINE PROCESS PUMPS FOR LOW FLOW, HIGH PRESSURE APPLICATIONS “APCO-CHEM” Design Features of the One and Two Stage Turbine Type Pump A. Double suction and floating impeller balances axial thrust load. Sealing flexibility (mechanical seal or packing). Rigid shaft and short bearing span increase mechanical seal life. Single row radial and double row thrust bearings for extended life. Replaceable channel rings allow ease of maintenance. Balancing holes reduce axial thrust. Optional Design Features • Jacketed stuffing box for cooling or heating mechanical seal cavity. • Jacketed bearing...

REGENERATIVE TURBINE PROCESS PUMPS FOR LOW FLOW, HIGH PRESSURE APPLICATIONS Process Turbine Pump Principles of Operation Turbine pumps derive their name from the many buckets machined into the periphery of the rotating impeller. They have long since been recognized for their effectiveness in the areas of low flow, high head application. The turbine pump offers higher heads than centrifugal pumps. Because the head capacity curve is steep in a turbine pump, a greater degree of flexibility is available to the process engineer. Turbine pumps having top center line discharge are self-venting and have...
