MXQ DISK PUMPS

Disk pumps are a crucial part of various industries including oil & gas, pulp & paper, chemical, food & beverages, and wastewater treatment. They vary in type and designs depending on the application. MXQ’s industrial disk pumps are manufactured using the latest technology that helps eliminate the issue of clogging. These pumps can be customized to function as impellers. Our disk pumps are sturdy and designed to handle all kinds of fluids with varying viscosities and solid matter. Any standard C-faced motor available in your store room can be used to operate our disk pumps as their disks have a low radial load.

Overview


MXQ industrial disk pumps are specially designed to meet your niche requirements. Our disk pumps are abrasion and corrosion resistant. The company’s newly-designed disk pumps have a lower net positive suction head required (NPSHR) than most other disk pumps available in the market with an 5%–9% better efficiency than other disk pumps. Our cutting edge technology offers close coupled pumps, which help reduce space allocation and save costs. To avoid cavitation, this is the minimum pressure required at the pump’s suction port. Our disk pumps can stand viscous fluids, trapped air, particulate matter and solids in fluids, and slurries. They are extremely versatile and durable, and require minimal to no repairs and spare parts replacement.

 


Features


Disk pumps are primarily centrifugal pumps; however, they have the capacity to perform the functions of other types of pumps such as gear and progressive cavity.

  • Disk 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.
  • As much these pumps can handle viscous fluids and solids, they can process fragile products without any damage.
  • In disk pumps, the liquid is contained in between the two shrouds and rotates along with them.
  • 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 disks have low radial and axial loads, which help increase their life span.
  • 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.

 


Operation


Disk 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:

  • Disk 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 disks.
  • 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 disk, 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.

 


Applications


Disk 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
