Disk Pumps

Disk Pumps

MXQ Disk Pumps use the latest improved designs of disk pump technology, avoiding any clogging or plugging. They can also be retrofitted to replace impellers from open, semi-open, recessed, and air/gas entrained particles, high solids, and high viscosities. This efficiency is 5-9% better than other disc style pumps. Due to the low L3D4 radial load to rotating disk within the pump housing any standard C-faced motor from storeroom stock can be used. (No special proprietary motor needed for back-up spares.)  MXQ Disk Pumps are 100% interchangeable with other pumps on the market such as Mission, some Crane Deming, and other slurry disk pumps.

Our disk pumps are designed for the most abrasive and erosive particulates, slurries and sludges.  They gently handle the most fragile crystals, sensitive chemicals, and polymer emulsions.

MXQ Disk Pumps are specifically engineered products designed to meet your challenging process requirements. Our pumps are built for toughness and durability against abrasive slurries, sludge, drilling scale, coatings, and filter press feeds. With a unique design, the MXQ Disk Pumps can move pipe-size solids without clogging or plugging as other pumps can. MXQ Disk Pumps use the latest improved designs of disk pump technology. They can also be retrofitted to replace impellers from open, semi-open, recessed, and entrained air/gas entrained particles, high solids, and high viscosities.

The newly-designed MXQ Disk Pump has lower NPSHR and is among the lowest in the centrifugal pumps market. This efficiency is 5-9% better than other disc style pumps. Cutting edge technology offers close coupled pumps which save you money and reduce space allocation. Due to the low L3D4 radial load to rotating disk within the pump housing any standard C-faced motor from their storeroom stock can be used. (No special priority needed for back-up spares.)

MXQ Disk Pumps’ bearing frames are constructed in a heavy duty rigid MXQ Disk Pumps are 100% interchangeable with other pumps on the market such as Mission, some Crane Deming, and other  slurry disk pumps, which saves you  money. All pumps are non-witnessed Hydro tested prior to shipping to ensure the highest quality and reliability.

Wide Range of Applications

  • Abrasive Fluids
  • Viscous Fluids
  • High Solid Slurries
  • Air-Entrained Fluid

Low Shear

  • Fluids with Shear Sensitivity

Low NPSH

  • The disk rotor’s low NPSH ranges from approx. 1/3 to 1/2 that of a conventional centrifugal pump in the same service.

No Tight Internal Tolerances

  • This allows the disk rotor pump to pass large and irregular hard solids, as well as variable solids stream without plugging.

Pulsation-Free Smooth Laminar Flow

  • Pulsation-free flow enhances gentle processing of fragile products and eliminating costly damage along with greatly reducing wear in pump and related piping and instrumentation.

Dry-Run Capability

  • The disk rotor pump design is capable of being operated indefinitely with zero process fluid. (NOTE: The mechanical seal must be flushed during dry-running.)

Dead-Heading Discharge

  • It is possible to deadhead the discharge for extended periods of time at normal operating speeds with minimal damage to the pump.

Starving the Suction

  • It is possible to starve the suction for extended periods of time at normal operating speeds with minimal damage to the pump.

Few Spares Needed, ever.

  • Disk rotor pumps are subject to minimal wear even in the most abrasive services. The oversized shaft along with minimal axial or radial loads greatly extend and maximize bearing and seal life.

How do Disk Pumps operate?

Fluid is confined between the twin rotating shrouds and rotates with the shrouds. Because that layer of fluid immediately adjacent to the shroud remains “fixed” relative to that shroud face and subsequent layers of fluid resist separation from the adjacent layer, the entire fluid mass begins to rotate. As the fluid gains energy it moves outward on the “MXQ Disk” gaining additional energy and continues on. The actual path of the fluid through the pump becomes a spiral path. The MXQ Disk Pump displays similar (but not identical) diameter, RPM and pressure relationships to that of conventional impeller pumps. The reason for any departure is that fluid velocity is not fixed by the local disk velocity but is rather a function of disk spacing, fluid viscosity/density, radial velocity, and disk velocity. The flow in the rotating disks falls somewhere between forced vortex and free vortex circulation.
