Liquiflo Pumps


  • LIQUIFLO PUMPS is an international company that engineers, manufactures, and markets sealed and mag-drive gear pumps and centrifugal pumps.
  • Since 1972, LIQUIFLO PUMPS has been a leading manufacturer of high-alloy gear pumps and centrifugal pumps – designed specifically to meet the demanding needs of the chemical processing industry. LIQUIFLO gear pumps have handled thousands of difficult chemicals and have been successfully applied in many difficult pumping situations, including high-viscosity, high-pressure and high-temperature applications.
  • One of LIQUIFLO PUMP’s best achievements is the application of gear pumps to low-viscosity fluids by using a wide variety of non-metallic, self-lubricating components. In addition, LIQUIFLO PUMPS was one of the first companies to apply magnetic-drive technology to gear pumps. By focusing mainly on chemical applications, LIQUIFLO PUMPS has earned its reputation as one of the world’s leading pump companies.


Ideal for low– Flow and high, Pressure applications.

Virtually no pulsations – Ideal for metering applications.

Flow accuracies of 0.5-2.0% are achievable.

Require less auxiliary equipment than Diaphragm pumps (Pulsation dampeners, Air compressors, Dryers, etc.)

No check valves to clog

No diaphragms or hoses to rupture and leak

Reliable – High MTBM (mean time between maintenance)

Simple to understand and maintain – Repair kits are available which contain all components to completely and easily rebuild all Liquiflo gear pumps to like-new condition

Self-Priming/Suction lift capability

Low NPSHR – Smaller pipe diameters are required

Useful over a wide range of viscosities (0.3 to 100,000+ cP)

Bi-directional flow – Interchangeable suction & discharge por

Mag-Drive Gear Pumps:

• Provide the simplest and best method for containing hazardous liquids

• Are ideal for applications where absolutely no leakage can be tolerated

• Are typically less expensive than double-sealed arrangements

• Eliminate cooling loops required on double-sealed arrangements

• Eliminate the need to dispose of barrier fluids used on double-sealed pumps

• Require less maintenance than mechanically-sealed pumps since there are no seals to replace
