Blackmer Gear Pumps

This page focuses on gear pumps for liquid handling. Selection should address viscosity, compatibility, pressure, and the required delivery rate.

An outer rotor and an internal gear create spaces that fill at the inlet and carry liquid toward the discharge. Suitable liquid supply and clearances are important to performance.

It is an internal gear range with multiple material and sealing configurations. Review model-specific performance and compatibility for the intended duty.

It uses magnetic torque transmission across a containment barrier instead of a conventional dynamic shaft seal. Confirm fluid suitability and the operating limits of the selected design.

No. Their pumping elements and service requirements differ. Use the exact model and pumping principle when selecting parts or investigating performance problems.

Certain configurations are intended for replacement applications. Verify the cross-reference, materials, driver, connections, and performance before treating the proposed pump as interchangeable.

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.
