Projects are revised
Changes in media, flow, pressure and installation layout can leave purchased pumps outside the final equipment scope.
Surplus industrial progressive cavity equipment
Unused project pumps. Duplicate maintenance spares. Packages released after a process upgrade. We work with companies looking to sell excess industrial progressive cavity pumps.
Discuss selling your surplus cavity pumps →Start with nameplate photos, equipment scope, condition and your location.
How surplus develops
Progressive cavity pumps use a rotor and stator arrangement to move material through progressing cavities. They are selected for particular media, flow requirements and operating conditions. A revised process or retired line can leave equipment purchased for the original application without a clear next role.
Changes in media, flow, pressure and installation layout can leave purchased pumps outside the final equipment scope.
New production methods, upgraded treatment systems and discontinued products can release pump packages and dedicated maintenance spares.
Duplicate stock, revised backup requirements and site closures can reveal more pumping equipment than operations need.
Confirm with maintenance and process engineering which units remain required for active service, backup capacity or planned projects before releasing equipment.
Identify what is available
We welcome inquiries about individual pumps, complete packages and identifiable spare parts. Categories can overlap; use the actual model and configuration to describe each item.
Progressive cavity units held for documented industrial services. Include model, size, stage information and available operating specifications.
Open-inlet or hopper arrangements, with feed mechanisms where supplied. Identify hopper dimensions, feed components and known original media.
Units identified for controlled delivery duties. Record drive arrangement, documented capacity and included control equipment.
Models documented for specific hygienic applications. Preserve material, seal and cleaning documentation rather than inferring suitability from a stainless exterior.
Pumps supplied with motors, gear reducers, baseplates and controls. Identify each major component separately and state what is missing.
Identified rotors, stators, seals, joints and related components. Include full part codes and known matching pump models.
Recognizable names. Specific configurations.
Common names found on progressive cavity equipment include the manufacturers and product families below. Other brands and legacy units are welcome in an inquiry.
NETZSCH / NEMO · SEEPEX · Moyno · Mono · PCM · WANGEN · Roto Pumps
Brand names identify equipment only. Surplus Cavity Pumps does not claim manufacturer authorization, endorsement or affiliation.
Pump model options can distinguish rotor geometry, stages, stator material, seals and construction. Photograph pump, motor and gearbox labels separately.
Condition and history matter
New units, stored unused equipment, used pumps and rebuilt packages should be described separately. Share original service, known media exposure, storage conditions and maintenance records.
Disclose rotor wear, stator deterioration, leakage, damaged joints, corrosion, drive faults, modifications and missing parts. Unused stock may still need evaluation of elastomer condition and storage history.
For rebuilt equipment, include the documented work scope. Identify process residue and cleaning concerns before discussing handling or shipment.
Keep performance data in context
Share flow and pressure information with the stated speed and fluid conditions. Viscosity, solids, temperature and material compatibility can affect application suitability.
Record allowable differential pressure separately from connection ratings. Do not infer output or limits solely from motor power, flange size or a familiar model family.
Similar-looking parts may differ in geometry, stages, material and fit. Keep full codes and packaging linked to each spare rather than assuming interchangeability.
Progressive cavity equipment may be damaged by inappropriate dry running. Any testing, isolation or removal should be handled by qualified personnel using the specific manufacturer instructions.
From excess assets to a clear inquiry
An asset list, partial stock export or readable photos can establish the starting point. Be clear about what has been identified, inspected or tested.
Check active processes and backup requirements. Select pumps and spares no longer needed for current service or planned internal use.
Collect labels, photos and records. Identify complete packages, bare pumps, separate parts and known condition.
Share details, location and timing. Inventory fit, commercial terms, inspection needs and removal or transport responsibilities are confirmed for the specific assets.
Value and logistics belong together
Potential resale value depends on identification, configuration, condition, completeness, documentation and demand. A familiar brand or high original investment does not guarantee an offer.
Share dimensions, known weights, connection status and access constraints. Identify any residue or special handling requirements.
Agree on disconnection, cleaning, packing, loading and transport responsibilities before work begins. Retain manuals and keep accessories associated with the correct pump.
Common questions
Yes. Describe prior service, known media exposure, faults and last operation. Include photos and available records. Used or untested condition needs to be considered during review.
Yes. Identify them as bare pumps and list any baseplates, couplings or other parts supplied. Disclose missing components.
Include them separately with full part codes, condition and known matching models. Describe elastomer storage history and retain packaging where available.
Start with readable labels and overall photos. Share original order or service records where available and state which specifications are unknown rather than guessing.
Yes. Include rebuild scope, available test records and storage conditions. Do not represent equipment as verified operational stock solely because it was repaired or never installed.
Share the equipment you have. Whether a transaction makes sense depends on the units, quantities, condition and logistics. Any offer or commercial arrangement is confirmed after review.
