NETZSCH Pumps & Systems

The page includes progressing cavity, rotary lobe, peristaltic, and screw technologies, along with engineered packages. Each serves different fluid and operating requirements.

A rotor turns within a stator to create cavities that progress from inlet to outlet. Correct rotor and stator selection is central to performance.

Consider a suitable screw design when the required liquid transfer, viscosity range, and flow characteristics fit its capability. Different screw configurations should not be treated as interchangeable.

Appropriate designs may provide gentle handling. Review speed, pressure, product properties, and acceptable changes in texture or structure.

Abrasion, unsuitable elastomers, excessive pressure, dry running, or other off-design conditions may contribute. Inspect the fluid and operating duty when wear is faster than expected.

Depending on scope, it may include mounting, controls, piping, and accessories. Define required protection and site interfaces before ordering.

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.
