Disc Pump

Category: Disc Pump

The Discflo Pump stands as a remarkable advancement in the realm of end suction Centrifugal Pumps, boasting a distinctive operational approach that sets it apart from conventional centrifugal pumps that are widely recognised.

What is a Discflo Pump?

At the heart of the Discflo Pump lies its exceptional impeller known as the Discpac, which operates on the principle of boundary layer and viscous drag. Comprised of concentric discs ingeniously joined together by carefully engineered spacers, the Discpac accommodates various product sizes and even handles solids, if necessary.

Disc Pump Applications

When the concern revolves around product degradation, product impingement, or the delicate nature of shear-sensitive substances, the Discflo pump emerges as the ultimate solution. This pioneering pump finds its ideal application in a variety of scenarios, including:

  • Pumping substances prone to damage or degradation, such as food products and delicate fruits.
  • Handling shear-sensitive materials with utmost care and precision.
  • Efficiently managing high-viscosity fluids, as the pump’s performance improves with increasing viscosity.
  • Tackling large solids without compromising their integrity.
  • Excelling in low NPSHa (Net Positive Suction Head Available) environments.
  • Effectively handling applications with high-entrained gases.

Operational Principle of the Discflo Pump

Leveraging the principles of boundary layer technology, the Discflo Pump operates uniquely. The layers closest to the Discpac remain stationary relative to the impeller’s rotational speed, while the velocity gradually increases as one moves towards the centre of the Discpac. This phenomenon occurs due to the viscous drag between each layer.

Remarkably, this design ensures that the product does not collide forcefully with the Discpac, unlike traditional centrifugal pumps, thereby preserving the state and integrity of the fluid being handled. Additionally, the Discflo pump’s innovative design allows it to handle large solids without causing any damage.

Benefits of Choosing a Discflo Pump

The foremost advantage of the Discflo Pump lies in its extraordinarily low NPSHr (Net Positive Suction Head Requirement) characteristic. This unique attribute greatly reduces or eliminates cavitation within the pump, particularly under challenging suction conditions. Moreover, the pump exhibits exceptional performance even when dealing with entrained gases and operates flawlessly against closed suction and discharge lines, without compromising its efficiency.

Another notable benefit stems from the operational principles of the Discflo Pump, as it minimizes the need for spare parts and maintenance. The boundary layer and viscous drag characteristics inherent in the pump design mitigate wear and tear, resulting in reduced spare parts inventory and minimized equipment downtime. Consequently, both maintenance and operational costs are substantially reduced.
