Primary Product Pillar
Mechanical Seals for Industrial Pumps and Agitators
Select a seal family below or send the pump model, duty data, drawing, or failed sample. We support product identification, material review, and build-to-spec replacement inquiries.
Product Families
Find the Seal by Design and Duty
The seal family narrows the design route; the equipment interface and operating duty determine the actual build. Each technical page explains selection boundaries, RFQ inputs, material decisions, and the review sequence.
- 01Cartridge Mechanical SealsPre-assembled cartridge seal configurations for industrial pumps, supplied against pump data, drawings, dimensions, or an existing seal sample.Typical use: Centrifugal pumps · Chemical process pumps · Water and wastewater pumps→
- 02Metal Bellows Mechanical SealsElastomer-free bellows seal options for temperature-sensitive, corrosive, or fouling services where secondary-seal movement is undesirable.Typical use: Hot oil pumps · Chemical process pumps · Refinery services→
- 03Component Mechanical SealsSingle-spring, multi-spring, elastomer-bellows, and PTFE-bellows component seals for pump repair, OEM assembly, and replacement programs.Typical use: Water pumps · Process pumps · Food and beverage equipment→
- 04Agitator & Reactor Mechanical SealsEngineered seal arrangements for top-entry and side-entry mixers, agitators, and reactors based on vessel pressure, shaft movement, and process duty.Typical use: Chemical reactors · Mixing vessels · Fermentation equipment→
- 05OEM-Compatible Replacement Mechanical SealsBuild-to-sample and build-to-drawing replacement seal support for pump models, discontinued parts, and distributor cross-reference programs.Typical use: Pump repair shops · Mechanical seal distributors · MRO teams→
- 06Mechanical Seal Support SystemsAuxiliary piping and support components configured around the selected seal arrangement and agreed process requirements.Typical use: Barrier-fluid systems · Buffer-fluid systems · Flush and quench arrangements→
Engineering Input
A Useful RFQ Starts with the Operating Duty
A pump model or seal code identifies geometry. Fluid properties and duty determine the face pair, secondary seals, metallurgy, arrangement, and support plan. Unknown fields can be marked for joint review.
- 01Equipment interface
- Pump make, model, seal code, shaft or sleeve diameter, chamber dimensions
- 02Process conditions
- Fluid composition, solids, normal and maximum pressure and temperature
- 03Motion and arrangement
- Speed, direction of rotation, single or double arrangement, available utilities
- 04Commercial scope
- Existing materials, failure symptoms, quantity, documentation and required date

Application Paths
Start with Your Process Industry
Application pages connect operating problems to relevant seal families, replacement components, and RFQ information.
For Pump & Equipment OEMs
Submit interface dimensions, duty range, validation requirements, expected quantities, and documentation needs.
For Distributors & Repair Shops
Send target models, annual demand, sample or cross-reference data, packaging, and private-label requirements.
For Plant MRO Teams
Share the installed equipment, current failure mode, shutdown window, and service conditions to focus the review.
Mechanical Seal FAQ
What information is needed to select a mechanical seal?+
Provide the pump manufacturer and model, shaft or sleeve diameter, fluid, operating and maximum pressure, temperature, speed, solids content, arrangement, materials, quantity, and any current failure symptoms. A drawing, nameplate photo, or used seal sample can reduce ambiguity.
Can you review a replacement seal from a sample or drawing?+
Yes. We can review a dimensional drawing, pump model, seal code, clear photos, or a usable sample. Compatibility is confirmed only after dimensions, materials, direction of rotation, and operating conditions are checked.
Do you supply seals for distributors and pump repair companies?+
Distributor, repair, OEM, and MRO inquiries are welcome. Include the expected order pattern, target models, packaging or private-label requirements, and documentation needs so the supply program can be evaluated correctly.
