The Disc Pump ConceptThe Disc Pump Concept

The Discflo disc pump is a highly innovative design of pump, operating on the forces of boundary layer and viscous drag.

The pump mechanism is the Discpac which provides laminar, pulsation-free flow and ‘non-impingement’ pumping.

Benefits Part I: Pump Operating & Design Features

Non-impingement operation– leading to little abrasive wear, no destruction of delicate and

shear sensitive products, no emulsification

Pulsation-free, laminar flowLow NPSH requirementNo close tolerancesHighly versatile designPumps the same range of heads and flow rates as centrifugal and PC pumps

Minimal downtime– due to lack of close tolerances and laminar flow

Ability to run bone dryAbility to deadhead discharge and starve suctionNo radial loads, so longer seal and bearing lifeVery low axial loads, so longer seal lifeExceptionally LOW LIFE CYCLE COSTS

– disc pump saves up to 90% of spare parts, maintenance and downtime costs compared to other pump designs

Benefits Part II: Pump Operating & Design Features

Highly viscous fluidsHighly viscous fluidsSlurries with up to 80%+ solids contentSlurries with up to 80%+ solids contentSeverely abrasive fluidsSeverely abrasive fluidsFluids with high volumes of entrained air or gasFluids with high volumes of entrained air or gasFluids containing large or stringy solidsFluids containing large or stringy solidsDelicate solidsDelicate solidsShear sensitive fluids and emulsionsShear sensitive fluids and emulsionsHigh temperature and high pressure fluids (APIHigh temperature and high pressure fluids (API--610)610)

Benefits Part III: HardHard--toto--Pump Fluid ApplicationsPump Fluid Applications

Applications in IndustryApplications in Industry

Pulp and paper mill applications: – chemical recovery, paper coatings, stock, waste, etc

Chemical, oil and petroleum processing: – emulsions, crystal slurries, acid slurries, oil and sand sludge, plastics,

paint, hazardous waste, etc

Wastewater - municipal and industrial: – sewage, primary/secondary sludge, anaerobic sludge

Food processing and other sanitary applications: – corn slurries, chicken parts, soft fruits, dairy, etc

Metal, mining and other specific markets:– steel mill sludge, nuclear waste, mine dewatering, etc

Operating Range and SizesOperating Range and Sizes

Pumps are configured for an application by varying the size, number and spacing of discs in the Discpac:

– Discpac diameters from 8” [203mm] to 20” [508mm]

Suction and discharge size range:– 2” x 1.5” [50mm x 40mm] to 12” x 8” [300mm x 200mm]

Flow rates range from 2-10,000 GPM [0.5 m3/h-2250 m3/h]

Discharge pressures up to 1000ft [300m]

User: Steel Mill in PAProduct: Hot (1800F) hydrofluoric/nitric acid solution with 1/2-inch brick particlesInstalled: 6 disc pumps installed in 1993Replaced: centrifugal pump units

Company calculated costs of centrifugal

• parts costs in one year = $207,960 (cases, impellers, seals, etc.)

• maintenance labor costs = $10,714

• quality loss due to damage = $18,879

Total cost: $237.553

Disc Pump PricingDisc Pump Pricing

Discflo has developed a software program, called Autoselect, to allow distributors to select and price disc pumps and pump accessories directly for customers.

Remember: The disc pump is a problem-solving pump. It can greatly reduce Pump Life Cycle Costs by cutting maintenance, downtime, and spare parts requirements in hard-to-pump applications, as well as giving higher product yields in shear sensitive and delicate applications.
