TEC TOTAL EQUIPMENT COMPANY DISC FLOW DISC PUMP 3" FLANGED INLET AND 3" FLANGED OUTLET SC/SC/SC/SC/VITON/316SS 6401 A194 DATE: 11/20/09. DURAMETALLIC / FLOWSERVE 1.750-INCH INDUSTRIAL DOUBLE MECHANICAL CARTRIDGE PUMP SEAL THE DISCFLO MODEL 303-12 DISC PUMP IS A HIGHLY SPECIALIZED HEAVY-DUTY INDUSTRIAL 316 STAINLESS PUMP MANUFACTURED BY DISCFLO CORPORATION. INSTEAD OF USING STANDARD IMPELLERS OR LOBES IT RELIES ON A PATENTED "DISCPAC" (DISC PACK) ASSEMBLY. THE "303" INDICATES THE PHYSICAL FRAMING/GEOMETRY OR SERIES SIZE WHILE THE "-12" COMMONLY DESIGNATES THE 12-INCH DIAMETER OF THE DISCPAC OR A 12-INCH SPACING CONFIG DESIGNED TO PREVENT RAGGING. CORE OPERATING PRINCIPLE: THE PUMP OPERATES USING TWO FUNDAMENTAL FLUID MECHANICS PRINCIPLES: BOUNDARY LAYER: A STATIONARY LAYER OF LIQUID MOLECULES ADHERES TO THE SPINNING DISCS CREATING A PROTECTIVE CUSHION. VISCOUS DRAG: THIS BOUNDARY LAYER GENTLY PULLS SUCCESSIVE LAYERS OF LIQUID THROUGH THE PUMP IN PARALLEL STREAMS. LAMINAR FLOW: BECAUSE THERE ARE NO BLADES COLLIDING WITH THE FLUID IT PRODUCES A NON-PULSATING LOW-SHEAR ENTIRELY SMOOTH MOVEMENT. KEY SPECIFICATIONS & PERFORMANCE: NO CLOSE TOLERANCES: FEATURES LARGE INTERNAL CLEARANCES (OFTEN STARTING AT 1/8" MINIMUM). HIGH SOLIDS CONTENT: CAPABLE OF PASSING UP TO 80% SOLIDS BY VOLUME WITHOUT CLOGGING OR RAGGING. VISCOSITY RANGE: HANDLES HIGHLY VISCOUS MATERIALS MEASURING UP TO 200,000 TO 700,000 CPS. AIR/GAS ENTRAINMENT: PUMPS FLUIDS CONTAINING UP TO 70% ENTRAINED AIR OR GAS WITHOUT SUFFERING FROM VAPOR LOCK OR CAVITATION. ZERO RADIAL LOADS: THE SMOOTH FLOW MINIMIZES STRAIN YIELDING A BEARING LIFE THAT FREQUENTLY EXCEEDS 80,000 HOURS IDEAL HIGH-PERFORMANCE APPLICATIONS: BECAUSE THE FLUID NEVER IMPACTS A RIGID IMPELLER BLADE THIS PUMP MODEL IS HIGHLY FAVORED FOR THE TOUGHEST APPLICATIONS ACROSS INDUSTRIES: MUNICIPAL WASTEWATER: MOVING PRIMARY SLUDGE RETURN ACTIVATED SLUDGE (RAS) WASTE ACTIVATED SLUDGE (WAS) LIME SLURRY OR CHEMICAL MIXTURES WHERE SAND CRYSTALS OR GRIT WOULD QUICKLY ERODE CENTRIFUGAL IMPELLERS. SHEAR-SENSITIVE MATERIALS: SAFELY TRANSFERRING POLYMERS EMULSIONS DELICATE CRYSTALS OR LATEX WITHOUT TEARING OR BREAKING DOWN THE MATERIAL'S MOLECULAR STRUCTURE. OIL & GAS / MINING: TRANSFERRING DRILLING MUDS TOXIC HAZARDOUS WASTES AND TANK. BOTTOMS WITH MINIMAL WEAR. MAINTENANCE & LONGEVITY ADVANTAGE: STANDARD PUMPS OPERATING UNDER HARSH CONDITIONS REQUIRE FREQUENT INTERNAL REPLACEMENTS. BECAUSE THE ABRASIVE MATERIAL TRAVELS DOWN THE LOW-VELOCITY CENTER AWAY FROM THE ACTUAL DISC SURFACES THE PUMP ITSELF EXPERIENCES ALMOST ZERO EROSION WEAR. COUPLED WITH A PROTECTED MECHANICAL SEAL IT IS CAPABLE OF RUNNING COMPLETELY DRY OR UNDER STARVED SUCTION CONDITIONS WITHOUT BREAKDOWN.
