The Discflo Disc Pump is solving some of the toughest pumping problems in pulp and paper manufacture. The Discflo Stock Pump is able to pump paper stock densities up to 16% is unique in the industry, while the pump’s non-impingement action prevents damage to paper fibers.

The Disc Pump also excels at handling:

• Abrasive and viscous slurries from the chemical recovery process
• Shear sensitive chemicals, such as paper coating slurries
• Sludges with a high solids content or high levels of entrained air

The Discflo Stock Pump can handle up to 70% entrained air or gas without cavitating.

Laminar Flow Solves Problems

Disc Pumps achieves this exceptional performance thanks to its unique pumping mechanism, the Discpac. The Discpac uses the principles of boundary layer and viscous drag to create  Pulsation-free, laminar flow through the pump, with minimal contact between the pump and pumpage.  The result is a cost-effective alternative to centrifugal, progressive cavity, lobe and screw pumps.

For over 20 years, Discflo pumps have successfully replaced centrifugal and progressive cavity pumps in the chemical industry’s toughest pumping applications.

Our pump’s unique non-turbulent, non-impingement mechanism is designed specifically to handle:

• Abrasive
• Corrosive
• shear sensitive
• Viscous
• High-solids
• Gas-entrained slurries.

Plus, our pump boasts one of the lowest life-cycle costs in handling these tough applications by reducing pump wear and spare parts costs, while increasing uptime and, in the case of shear sensitive products, product yield.

A wide range of Disc Pump models is available, including horizontal end-suction, close-coupled, ANSI, API-610, and submersible configurations, for flow rates from 2 GPM to 10,000 GPM  - 1  to 1000 Meter Cubed an Hour .

Discflo’s Disc Pumps have been employed throughout industry to solve some of the toughest pumping problems. Our pumps excel at handling:

• High viscosity fluids
• Severely abrasive products
• High-solids slurries
• Slurries containing large or stringy solids
• Air- or gas-entrained fluids up to 80% by volume,
• Shear sensitive and delicate fluids.

Outlasting the Competition

In such harsh environments, Disc Pumps have proven successful in cutting maintenance and parts costs, and providing unheard-of reliability. Typically, Disc Pumps outlast centrifugal, gear and lobe pumps over four times.

Maritime Environments

The Disc Pump’s ability to handle delicate product without damaging or degrading it has lead to successful applications in marine environments, such as shrimp fishing and pumping live algae at the Harbor Branch Oceanographic Institute.

A Chemical manufacturer  has found the Discflo technology to  be the best solution for pumping shear sensitive latex.

In less than a month of operation, the Discflo pump had increased productivity approximately 12%.

Prior to using the Discflo, they used a mixed bag of pumps consisting of everything from Standard end-suction centrifugal’s to Air operated double diaphragm types, to move their highly shear sensitive latex product.

In all cases, the latex would shear in the pump and discharge a high concentration of solids downstream.

Eliminating the solids or shearing problem raised productivity. However  the 12% figure does not take into account the annual savings they will enjoy in reduced down time and prolonged filter life.  Before they were changing filters every 4 to 5 days.

• Viscous slurries to 100,000 cPs
• High-solids fluids to 90% solids
• Abrasive and/or corrosive fluids
• Large and stringy solids up to 8″ in diameter
• High temperature/pressure applications.

We have served many Fortune 500 companies, including:

• Texaco
• British Petroleum
•  Arco
•  Mobil
•  Chevron
• Maersk.

Avoiding Cavitation Problems, if the below check list does not solve your problem A Low NPSH pump like a Discflo may be the solution:

The available NPSH of the system must be equal to or greater than the NPSH required by the pump in order to avoid cavitation difficulties. In most cases cavitation may either be avoided or corrected by any one or combination of the following practices:

Keep available NPSH as high as possible by:

Keep the pump discharge head as near the specified head as possible and correct systems which are at fault in this respect by:

Where increasing the discharge head will not correct trouble.
