Liberty Process Equipment FAQ
What is Liberty Process Equipment?
Liberty Process Equipment provides progressive cavity pumps, replacement pump parts, and fluid-handling solutions for industrial applications. Their equipment is particularly useful for moving viscous, abrasive, solids-containing, and difficult-to-handle materials.
What types of pumps does Liberty Process offer?
Liberty Process specializes in progressive cavity pumps and related pumping equipment designed for industrial process, wastewater, chemical, food processing, and material-transfer applications.
What industries use Liberty Process pumps?
Liberty Process pumping equipment is used in wastewater treatment, chemical processing, food and beverage production, oil and gas, mining, manufacturing, agriculture, and other industrial fluid-handling applications.
What is a progressive cavity pump?
A progressive cavity pump uses a helical rotor rotating inside a stator to create sealed cavities that move fluid through the pump. This positive displacement design provides consistent flow and works particularly well with thick or difficult-to-pump materials.
What are progressive cavity pumps commonly used for?
Progressive cavity pumps are frequently used to move sludge, slurries, wastewater, chemicals, oils, pastes, polymers, food products, and other viscous or solids-containing materials.
Can Liberty Process pumps handle high-viscosity fluids?
Yes. Progressive cavity pumps are particularly well suited for high-viscosity fluids because they provide consistent displacement without relying on the higher fluid velocities associated with many centrifugal pump applications.
Can progressive cavity pumps handle solids?
Yes. Depending on the pump configuration and application, progressive cavity pumps can handle fluids containing suspended solids and other difficult materials.
Are progressive cavity pumps good for metering applications?
Yes. Because progressive cavity pumps provide predictable flow in relation to operating speed, they can be well suited for dosing, metering, and applications requiring controlled fluid delivery.
How do I know which Liberty Process pump is right for my application?
Proper selection depends on required flow, discharge pressure, viscosity, solids content, temperature, chemical compatibility, abrasiveness, and system conditions. Evaluating the complete application helps determine the appropriate pump and materials of construction.
What are signs that a progressive cavity pump may need service?
Common warning signs include reduced flow, inconsistent pressure, unusual noise, vibration, leakage, increased operating temperatures, declining efficiency, or unexpected changes in pump performance.
What maintenance do progressive cavity pumps require?
Routine maintenance may include inspecting the rotor, stator, seals, bearings, drive components, and lubrication. Monitoring performance and replacing wear components at appropriate intervals can help prevent unexpected failures.
Can progressive cavity pumps be repaired or rebuilt?
In many cases, yes. Rotors, stators, seals, bearings, and other wear components can often be replaced to restore performance and extend the service life of the pump.
Can preventative maintenance reduce pump downtime?
Absolutely. Regular inspections help identify worn stators, rotors, seals, bearings, and other developing problems before they result in a major failure or unplanned shutdown.
Does Industrial Air Services provide Liberty Process pump service and support?
Yes. Industrial Air Services provides Liberty Process pump support, troubleshooting, preventative maintenance, repairs, replacement equipment, parts assistance, and application support throughout Nashville, Murfreesboro, Franklin, Clarksville, Knoxville, Chattanooga, Bowling Green, and surrounding areas.
Can Industrial Air Services help select a replacement Liberty Process pump?
Absolutely. Industrial Air Services can evaluate your existing equipment, process fluid, flow and pressure requirements, viscosity, solids content, and operating conditions to help determine the appropriate Liberty Process pumping solution.
