Liberty Process Pumps

This page focuses on progressive cavity pumps, associated replacement parts, dosing options, and complete packages for industrial fluid handling.

It uses a rotor and stator to move enclosed volumes rather than an impeller. The two designs have different selection, control, and maintenance requirements.

A suitable configuration can be evaluated for these duties. Supply viscosity, solids data, flow, pressure, and inlet conditions for selection.

Compatibility requires verification of the exact pump, part dimensions, materials, and operating duty. Confirm the cross-reference before assuming a direct replacement.

The elastomer must suit the chemical, temperature, and mechanical duty. Swelling, hardening, or excessive wear can affect flow and service life.

It may provide controlled delivery in a suitable application. Verify output under actual pressure and fluid conditions and select the drive and controls for the required adjustment range.

Viscosity influences inlet losses, required torque, internal slip, and permissible speed. Provide fluid behavior across operating temperatures so the pump and drive can be selected together.

A positive displacement pump can continue displacing liquid against a restriction. The system needs correctly selected pressure protection and controls within the ratings of the pump and connected equipment.

Worn pumping elements, inadequate inlet supply, changed viscosity, or incorrect speed may reduce delivery. Compare operating pressure, temperature, and speed with the original duty.

Suitability depends on particle size, hardness, concentration, pump design, and speed. Describe the actual solids so materials and expected wear can be evaluated.

The allowable conditions depend on the technology and model. Confirm dry-run limitations and protective controls; never transfer a dry-running claim from one pump design to another.

Cold or thick product, blocked discharge, internal damage, or excessive speed may raise torque demand. Review process conditions and protection settings with qualified personnel.

Follow the specific design's instructions for pumping elements, seals, bearings, and drive components. Record flow, pressure, temperature, and wear so service can be planned around actual conditions.

Often, but inspection and model identification are necessary. Compare the complete repair scope with replacement and confirm that new parts preserve the required clearances and material compatibility.

Contact Process & Power at (901) 362-5500 with your location, equipment identification, and application or service concern. The team can review selection, parts, and service options for your needs.

Include the required duty, fluid or process details, operating conditions, utilities, and installation dimensions. For existing equipment, add nameplate photos, model and serial numbers, and a description of the problem or planned change.
