Performance Life Cycle: Front Vane Open Style Impeller with Pump Out Vanes Reverse Vane Impeller and Repeatable Performance Performance Life Cycle: Flowserve Durco Reverse Vane Impeller with Balance Holes Effects of Wear • Thrust loads decrease as seal chamber gap widens • Chamber pressure increases as gap widens Effects of Impeller Adjustment to Seal Chamber • Original pressures and loads re-established after adjustment • Repeatable MTBPM cycle life The Reverse Vane Impeller has only one set of pumping vanes and one critical tolerance location – between the impeller and rear cover – to establish: • Performance • Efficiencies • Seal chamber pressures (i.e., mechanical seal MTBPM) • Thrust/axial loads (i.e., bearing life) Since an impeller can only be set in one direction, the reverse vane impeller has inherent advantages. Reverse Vane Impeller Consistent, Like-New Repeatable Performance Seal Chamber Pressure/Axial Thrust Effects of Wear • Thrust loads increase as seal chamber gap widens • Chamber pressure increases as gap widens Effects of Impeller Adjustment to Casing • Chamber pressures and bearing loads increase after each adjustment • Non-repeatable MTBPM cycle life The Front Vane Open Style Impeller has two sets of pumping vanes and two critical tolerance locations: • The front vane of the impeller clearance to the casing establishes: – performance – efficiencies • The impeller pump out vanes clearance to the rear cover establishes: – seal chamber pressures and seal life – thrust loads and bearing life Only One Tolerance Impeller Vanes To Cover Pump Performance Vanes Pump Out Vanes Reverse Vane Impeller Adjustment Front Vane Impeller Adjustment Front Vane Open Style Impeller Diminished Performance Thrust Seal Chamber Pressure/Axial Thrust Thrust Original Axial Thrust Original Axial Thrust Seal Chamber Pressure Original Chamber Pressure Seal Chamber Pressure Original Chamber Pressure Cycles Repeat Cycles Reduce Effects of Wear & Impeller Readjustment Effects of Wear & Impeller Readjustment 17 Pump Division ANSI Pump and Enhancements Improved Pump Reliability with Extended MTBPM at Low Flow Rates Flowserve extends its ANSI pump design for high head/low flow rates. • 1K1.5 x 1LF-4 • 1K1.5 x 1LF-8 • 2K2 x 1LF-10 • 2K3 x 1.5LF-13 Offered in a wide selection of metallurgy.

Applications • Tough sealing applications where a flush is impractical • Evaporator service • Continuously running pumps A choice of sealing arrangements Repeller chamber Repeller Liquid/air interface Stopped Running 39 . to evacuate liquid from the seal chamber. Advanced static seal options are available.Pump Division Mark 3 Sealmatic Dynamically sealing repeller eliminates the need for conventional mechanical seals. and the packed stuffing box design. Dimensionally interchangeable with all ANSI pumps. This family of repellers allows the Sealmatic to be used in applications having a wide range of suction pressures. This is accomplished by creation of a liquid interface seal in the repeller chamber that prevents leakage along the shaft during operation. Flowserve Durco Mark 3 Sealmatic Dynamically Sealing Repeller The Sealmatic Principle This pump does not leak while running because the Sealmatic design utilizes a repeller. The Sealmatic design is also available with unitized selfpriming and recessed impeller pumps.

Abrasive wear is minimized and solids integrity is maintained. stringy or fibrous slurries.Pump Division Mark 3 Recessed Impeller Trouble-free pump ing of solid. The circular flow path and tangential discharge also contribute to maximum pump life. thus maximizing mechanical seal and packing life. positive seal chamber pressure and to expel solids from the seal area. Applications • Abrasive waste water • Biological sludge • Clarifier underflow • 5% coke slurry • Diatomaceous earth slurry • Floculant sludge • Latex • Lime mud slurry • Organic slurry • Polymer slurry • Resin slurry • Rubber crumb slurry • Sodium hydroxide • Catalyst slurry Recessed Impeller 52 . The result is longer seal life as well as maximized radial bearing life. Delivers efficient operation and low NPSHr. Casing Dynamics The cylindrical volute design combined with the impeller spinning “out of the flow” minimize radial loads on the impeller. Vortex Pumping Action is your Best Choice for: • Erosive/corrosive slurries • Degradation sensitive crystals • Shear sensitive liquids • Stringy solids • Waste water Impeller Dynamics The vortex created by the spinning impeller does the pumping with less than 20% of the media actually contacting the impeller. Precision-cast impellers ensure peak energy efficiency and low NPSH requirements. The impeller is set to the rear cover plate – just like the standard reverse vane impeller. Rear pump-out vanes are used as necessary to ensure low.
