Disk Pumps – How Do They Work?

September 14, 2018


In the coating industry, various types of pumps are used for pumping abrasive fluids. The pumps often suffer from rapid wear and tear due to the presence of particulates in these fluids. Highly viscous fluids are known to choke the pump, and disrupt its operations. Sometimes, the steel shafts may break during the operation due to choking. This is where a disk pump can help. How does it help? What is its principle of operation? Read the post to know more.

Principle of Operation

The disk pumps make use of nature’s dynamic forces – laminar flow, viscous drag, and boundary layer. However, other pumps like gear or lobe pumps, positive displacement, or centrifugal pumps act in exactly opposite direction.

An Overview of Disk Pump Operation

The disk pump follows a natural dynamic principle – boundary layer – viscous drag, which is a non-impingement and non-contact technology. This technology has gained immense popularity in the recent years.

Under non-turbulent (laminar) flow conditions, the layers of liquid travel at different velocities. A drag force is exerted by the stationary pipe on the flowing liquid. The layer velocity of the pipe is zero under the strong drag force. However, layers that are parallel to each other will flow faster and at higher velocities at the center point of the pipe walls. This is a basic principle of operation of the disk pump.

Today, there are various types of disk pumps available in the market. All these pumps slightly differ from each other on the basis of their features. However, MXQ pumps have gained popularity in the recent years due to various reasons. What makes them special? Read the next section to know more.

Why MXQ Disk Pumps?

MXQ disk pumps have gained popularity in the industry due to the following:

  • The pump exploits the natural phenomenon – viscous drag and boundary layer. This feature helps it avoid radial loads.
  • Disks of the pump are rotated by a boundary layer of fluid molecules. This produces a buffer that helps create a separation between the pump and the fluid within.
  • MXQ disk pumps are unlike other conventional pumps due to their unique – no close tolerance design. These pumps perform better than conventional pumps, and outperform them in all applications.
  • The disk pumps can be customized to suit the harshest to gentlest pumping operations. These pumps can easily handle gaseous froths and sensitive solids, as well as handle slurries with high viscosity.
  • MXQ disk pumps enable smooth flow of fluid, which helps minimize wear and tear of the entire pump system.
  • Almost 75 – 80% of the solids can be easily pumped through this pump without clogging. The pump enables moving fluids with viscosities up to 100,000 cPs. Also, the pumps require less power than most compact sized centrifugal pumps.
