Using a unique operating system, known as the Discpac, the disc pump allows you to achieve an unheard-of level ofproductivity and exceptionally low Life Cycle Costs in difficult sanitary applications.• The disc pump can solve some of the toughest pumping problems in the sanitary market. It is ableto pump delicate foodstuffs such as corn, soft fruits, sugar crystals and fish, without damaging theproduct, and highly shear sensitive products like animal fats, dairy products, and citrus oils, withoutemulsifying the product, thereby increasing yields. In non-food industries, the pump is able to movedelicate products such as blood platelets, enzyme solutions and catalysts without destroying theintegrity of the product.The disc pump design is also ideal for viscous and abrasive slurries, and slurries with up to 80%solids, large and stringy solids, and/or slurries with highlevels of entrained air. Its unique, non-impingement design,coupled with laminar, pulsation-free flow, eliminates pump clogging, andexcessive wear due to abrasion.• The disc pump technology was developed in the late 1970s. The pumps are manufactured exclusively by the Discflo Corporation,founded in 1982, at its international headquarters in southernCalifornia, USA.DISCFLO’S MISSION is to become the number onemanufacturer of sanitary pumpsfor hard-to-pump applications We plan to achieve this throughcontinuous innovation in pumpdesign and technology, attention to quality in our manufacturing process and dedication to excellent customer service. In reaching our goal, we can help you reach yours—to solve your pumpoperating and maintenance problemsand produce a superior end-product.The Discflo SP Series pumpsallow you to achieve anunheard-of level of productivity,versatility and exceptionally low Life Cycle Costs in all your sanitary applications. THE DISC PUMP IS A HIGHLYINNOVATIVE PUMP. The disc pump is a highly innovative pump.From the outside, it has the appearance of acentrifugal unit, but it performs the work notonly of centrifugals, but also progressive cavitypumps, lobe and gear type pumps, and insome cases, chopper pumps. The SP Series of discpumps achieves flow rates from 2 to 3000 GPM[680 m3/h] and heads up to 800 ft [250 m].• Disc pumps operate on the principles of boundary layerand viscous drag. This pumping mechanism is new in the world of pumps, although these principles are known inother areas of fluid engineering, such as causing friction loss through a piping system. Under laminar flowconditions, streams of liquid travel at different velocities through a pipe. Fluid in the layer closest to the pipe isstationary due to drag forces, forming a boundary layer between the pipe and the rest ofthe fluid, while successive fluid layers flow faster towards the center of the pipe.• Similarly, when a fluid enters the disc pump, its moleculesadhere to the surfaces of the Discpac, a series of parallel discs whichare the heart of the disc pump. This creates a boundary layer. As thediscs rotate, energy is transferred to successive layers of molecules in the fluidbetween the discs through viscous drag, generating velocity and pressuregradients across the width of the Discpac. This combination of boundary layerand viscous drag causes a powerful dynamic force field that “pulls” the productthrough the pump in a smooth, pulsation-free flow. • The fluid being pumped moves parallel to the discs, and the boundarylayer creates a molecular buffer between the disc surfaces and the fluid.Consequently there is no impingement of the fluid on the moving parts ofthe pump. This distinguishes the Discflo pump from other pump systems,all of which use some kind of impingement device—such as a vane,impeller, lobe, hose or screw—to “push” product through the pump. • By minimizing contact between the pump and the material being pumped, wear on the discpump components is greatly reduced, pump breakdown is almost unknown and, in the case ofdelicate and shear sensitive materials, damage to the product by the pumping system is virtuallyeliminated. The disc pump’s problem-solving ability in hard-to-pump applications is unparalleled in the worldof pumps . . . making the disc pump truly the future of pump technology.The Disc Pump PrincipleDisc pumps have a non-impingementpumping action, with minimal contactbetween pump and fluid.Disc pumps employ theprinciples of boundary-layer adhesion andviscous drag, whichproduce pulsation-free,laminar flow.O P E R AT I N G D E S I G N F E AT U R E S• Very Low Life Cycle CostsProven reduction in spare parts required, maintenance and downtime, compared to all other sanitary pumps inhard-to-pump applications. Also, increased product yield, due to no damage to delicate foodstuffs or othersanitary products. See graph below.Features of the SP Series Pumps• Pulsation-free Laminar FlowPulsation-free laminar flow ensures no degradation ofdelicate products or damage to shear sensitive fluids,no dampening required later in the process, and lesswear on the surrounding pipework.• Non-Impingement PumpingOnce the boundary layer is formed, the product doesnot impinge on the Discpac, thereby reducing thelevel of abrasive wear to the pump, and eliminatingdamage to delicate and shear sensitive products.• No Close TolerancesThe disc pump is designed with no close tolerance,allowing the pump to handle large and stringy solidsas well as fluctuations in solids size and volume,without clogging.• Low NPSH RequirementThe disc pump’s NPSH requirement is about one halfto a third that of a standard centrifugal pump in thesame service conditions due to the smooth laminarflow within the disc pump.• Ability to Run Bone DryThe disc pump is able to run dry indefinitely becausethere is no direct metal-to-metal contact in the pump.Note: the mechanical seal must still be protected underthese conditions.• Deadheading Discharge/Starving SuctionIt is possible to deadhead the discharge and/or starve thesuction for extended periods of time at normal operatingspeeds, without damaging the pump. Note: seal flushingmust be continued under these conditions.• No Radial LoadsIn-house testing at Discflo proves that there are noradial loads on the disc pump shaft during operation,ensuring longer seal, bearing and shaft life.• Highly Versatile DesignHandles a wide variety of difficult fluids efficiently andeffectively, without breaking down in service. The samesystem can handle fluctuations in temperature, pressure,solids content and even product, without breakdown.Comparison of typical first-yearcosts (both acquisition and operat-ing) for three designs of sanitarypumps—lobe, centrifugal and discpumps—in a hard-to-pumpapplication: a viscous and abrasivefoodstuff at 100 gpm, 100ft TDH.LOBE PUMPCENTRIFUGAL PUMPDISC PUMPMechanism clogsImpellerreplacedMechanism clogsSeal failure due tohigh radial loadsLobes replaced due toexcessive wearDowntime due to rotorclearance adjustmentFIRST YEAR OF PUMP LIFE (in months)CUMULATIVE COSTS (in dollars)STANDARD PUMP CONFIGURATIONS & OPERATING RANGEThe SP Series of Sanitary Disc Pumps are an engineered product, manufactured to meet 3-A and internationalhygiene standards, and USDA requirements.

Proven success in handling delicatefoodstuffs, such as soft fruits, corn, rice, shrimp and fish, as well as shear sensitive dairyproducts, citrus oils and sugar crystals.• Highly Viscous FluidsBecause the disc pump uses friction, the higher the viscosity, the more efficiently it pumps.Fluids—including dairy sludge, molasses, peanut butter and pet food slurry—up to several100,000 cPs can be pumped. • Fluids Containing Large and/or Stringy SolidsDiscs in the Discflo pump can be spaced as far as 20 inches apart to handle largesolids, including whole chickens and other parts, soft fruits and live fish. Solidsentering the pump move to the midway point between the discs and pass throughthe pump without impinging on the moving parts.• Slurries with a High Solids ContentHandles slurries containing up to 80%+ solids without clogging, wearingexcessively or coming to a standstill. Examples include pumping rice and cornslurries and vegetable soup.• Severely Abrasive FluidsPumps the most severely abrasive fluids with minimal wear to the internal pump mechanism,due to the non-impingement operation. Examples include pumping slaughter house waste,sugar solutions and oyster shell slurries.• Fluids with High Volumes of Entrained Air/GasHandles fluids with very high levels of air/gas entrainment without vapor-locking or causingpump cavitation, including yeast and brewery sediment, egg whites, and cake mixes.
