Disc pumps are used for difficult pumping applications such as liquids with abrasives, solids, high viscosity, entrained gas or air.
They are also used to move shear sensitive liquids and to prevent emulsification. The mechanisms utilized to propel the fluids are mainly:

1. Centrifugal force
2. Friction in the form of boundary layer and viscous drag.

To pump an extremely shear sensitive liquid such as latex or even blood, we may utilize a two flat-plane DiscSet design sacrificing some efficiency in order to have more efficacy.
However, in most industrial applications, both efficacy and efficiency are desired. Therefore, the MXQ Disc Pump is offered with multiple Disc designs to increase both the efficiency and efficacy of the pump.

The SERRATED DISC design allows for more contact surface area than a typical disc perimeter and incorporates winglets holding the DiscSet together while accelerating the fluid through the system. The size, placement, and number of winglets vary according to the fluid being pumped.

We offer many DiscSet designs some of which are PATENTED OR HAVE A PATENT PENDING – Contact us for more info.

MXQ Disc Pump Brochure 2022




MXQ industrial disc pumps are specially designed to meet your niche requirements. Our disc pumps are abrasion and corrosion resistant. The company’s newly-designed disc pumps have a lower net positive suction head required (NPSHR) than most other disc pumps available in the market with an 5%–9% better efficiency. Our cutting edge technology offers close coupled pumps, which help reduce space allocation and save costs. Our disc pumps can withstand highly viscous fluids, trapped air, large solids, and slurries without blockages, obstruction, or cavitation. They are extremely versatile and durable, and require minimal to no repairs or spare parts replacement.



Disc pumps offer various advantages in hard-to-pump applications making them the future of pump technology. Some key features of these pumps are:

  • Disc pumps are capable of transferring abrasive, air-entrained fluids, as well as viscous fluids and high solid slurries. 
  • Fluids with particulate matter, solids, and trapped air can also be transferred through these pumps. 
  • Unlike the other conventional pumps, these pumps have no close tolerances, offer a pulsation-free flow and operate based on a non-contact pumping action. All the mentioned features contribute to high reliability and uptime by preventing solids from clogging
  • As much as these pumps can handle highly viscous fluids and solids, they can also process fragile products without any damage. 
  • They are sturdy and corrosion resistant; therefore, the wear and tear that occurs due to abrasive fluids is minimal. Therefore, both repairs and spare parts requirements are low.
  • They have dry-run capability. They can operate without processing fluid; however, in this case, the mechanical seal needs to be flushed.
  • Their discs have low radial and axial loads, which help to extend shaft, bearing, and seal life.
  • The net positive suction head (NPSH) required is far lower than most other pumps.

All these features reduce the overall cost and time in the long run.



Disc pumps are extremely versatile units. They have the appearance of centrifugal units, but can work like gear pumps, impellers, progressive cavity pumps, and chopper pumps. Here are some basic steps of their operation:

  • Disc pumps are designed on the basis of fluid engineering principle of boundary layer and viscous drag. This phenomenon facilitates the transfer of energy from the motor to the fluid. 
  • The pump has a boundary layer inside, which minimizes loss of friction and enables pulsation-free flow of the fluid. 
  • The molecules of the fluid entering the pump form the boundary layer by adhering to the surface of serial discs. 
  • This boundary layer and viscous drag together create centrifugal force that sucks in the fluid in a smooth, pulsation-free manner.
  • The rotation of the fluid along with the impeller discharges it to the other end of the pump. 
  • The pace at which this mechanical movement happens decides the discharge pressure. Other factors such as the diameter of the impeller, inlet fluid supply pressure, motor power, and so on affect the pressure and flow within the pump.
  • Along with the disc, the fluid also rotates and is pumped out in a spiral manner. 
  • The boundary layer reduces the contact between the fluid and the pump, thus eliminating corrosion, abrasion, or any other chemical reaction.



Disc pumps have applications across industries with varying requirements, especially processing hard-to-pump materials. They are commonly used in wastewater treatment by city-based municipal corporations. Here are a few important application areas:

  • Metals and mining: Drilling processes and precious metals recovery
  • Wastewater management: Filter aids, scum mixing, sludge handling processes and recirculation
  • Municipal corporations: Water treatment plants, recycling and purification
  • Food & beverage: Food processing industries to process canned sauces, soups, baby foods, fruit juices, breweries, beverages, hydrogenation, milk & milk products, crystallizing
  • Pharmaceutical: Salt crystal slurries, filter aid, and tablet coating 
  • Chemicals: Pumping of inks, chemicals, dyes, adhesives, paints, emulsions, foundries, varnishes, and gelatins
  • Oil & gas: Drilling processes for mud and crude oil, subsea cutting recovery, oil refining processes

Other general applications: Heat transfer, latex, cutting fluids, fertilizers, solid suspension, slurry mixtures, pulp & paper
