- No Close Tolerances
The Disc pump is not a centrifugal pump, positive displacement, gear, or lobe pump. Unique in design, the Disc pump bridges the performance gaps of conventional pumps and is capable of outperforming all of them in many applications.
- No Radial Loads
The Disc pump uses a new and patented technology that isn’t available in any other pump. The technology of the Disc pump harnesses the natural power of boundary layer and viscous drag.
- No Impingement
Boundary Layer - a boundary layer of fluid molecules collects, and rotates with the discs. This creates a natural, protective buffer that separates the pump from the fluid.
- Non Pulsating / Laminar Flow
Viscous Drag - Through viscous drag, the fluid is pulled through the pump without impingement. The boundary layer attracts and drags successive layers of fluid molecules into layered flows of parallel streams. This is the simple principle of viscous drag and in the Disc pump it is a powerful dynamic force that "pulls" the fluid through the pump in a smooth laminar, nonturbulent flow.
Rotary discs provide non-impingement pumping
— that means less wear and greater protection for your product.
- For Non-turbulent Pumping
• It is the Discpac that makes the Disc pump so revolutionary. All other pumps use some type of impingement device - relying on the force of impact to push the fluid through the pump. This impact is hard on shear-sensitive products, and it creates pulsation that wears the pump and damages piping. The non-impingement operation of the Disc pump makes it different than any other pump on the market today.
• The Disc pump uses a series of parallel discs called the Discpac. As the discs rotate, they create a boundary layer and viscous drag force that pulls the product smoothly into the pump. There is no destructive impact with an impingement device.
- To Handle Any Job
• The Discpac can be designed for the gentlest possible pumping of shear-sensitive solids and gaseous froths. At the same time it can handle aggressive slurries with heavy viscosities and highly abrasive solids content.
• The Disc pump can be designed with over-size suction and discharge.
• A wide variety of metal and non-metallic materials are available for the pump and its components and over a dozen configurations including API-610 and ANSI 2000 using Disc technology.
Cutting Edge Technology & Design Excellence
- No Reduced Performance Efficiencies
No close tolerances and no impingement device mean no metal-to-metal component wear.
- Low NSPH Requiements
Laminar flow means low NPSH! It prevents reduction in head and capacity and further reduces noise and vibration. The NPSHr is about half to one-third of a centrifugal pump in the same service conditions.
- Less Wear - No Pump Vibration
Smooth flow through the pump saves wear and tear on the entire pump system (and your product).
It also eliminates pump vibration and excessive noise.
- Open Design - Virtually Clog-free
The straight-forward design of the Disc pump conserves space and makes assembly and disassembly quick and easy. The open design prevents clogging. Optional pull out back.
Up to 80% solids by volume can be pumped without clogging. The pump has a unique open design and requires no close tolerances so even large and stringy solids won't get trapped or tangled inside.
A chicken processing plant couldn't find a pump that could handle their poultry waste without clogging. Then they found Discflo. Chicken parts, bones and even whole chickens pass easily through it's open, no close-tolerance design.
With no impingement device or close tolerances even large and stringy solids don't get trapped
There isn't another pump in the world that’s as powerful as the Disc pump when it comes to viscous product. With viscous drag, the fluid literally moves itself through the pump. The Disc pump actually becomes more efficient with increasing viscosities. The pump easily moves fluids with viscosities up to several 100,000 cPs. At viscosities greater than 350 cPs Disc pumps need less power than similar-sized centrifugal pumps.
A major U.S. paper recycling plant uses a Discflo for stock with consistencies of 8 to 18%. Discflo is the only pump that can do it without dilution. The ability to handle high viscosities can eliminate storage and vacuum systems, and save water and power, too.
Yes, you read that right, viscositys of several hundred thousand cPs.
