Quick Answer: CORASEALS is a pump mechanical seals supplier for centrifugal pumps, chemical pumps, slurry pumps, water pumps, and other rotating equipment. Send us your pump model, shaft diameter, seal chamber dimensions, fluid, pressure, temperature, speed, and existing seal drawing to get a quotation.
CORASEALS serves industrial end users, pump repair workshops, distributors, and OEM procurement teams. The product range covers replacement seals and new seal selection for clean water, wastewater, chemical, oil and gas, food processing, and slurry service. We supply cartridge seals, component seals, single mechanical seals, double mechanical seals, metal bellows seals, rubber bellows seals, and dry running seals.
A pump mechanical seal must be selected by duty conditions. A seal for clean water is not automatically suitable for abrasive slurry or hot oil. The correct seal selection depends on pump model, shaft diameter, seal chamber bore, seal chamber depth, fluid, pressure, temperature, and speed. Proper duty data reduces the risk of seal face damage, elastomer swelling, and early leakage.
CORASEALS can supply the following pump mechanical seal types:
For API 682 pump applications, we can check single, dual unpressurized, and dual pressurized arrangements from the duty data and seal drawing. Send the pump data sheet or API 682 arrangement code together with the shaft diameter and seal chamber dimensions.
Common seal face materials include silicon carbide, tungsten carbide, carbon graphite, and alumina ceramic. Elastomer materials include NBR, FKM, EPDM, FFKM, and PTFE. Metal parts are available in stainless steel 304, stainless steel 316, and other alloys. The correct material set depends on fluid chemistry, temperature, pressure, abrasive content, and the selected seal type.
We do not use a single material combination for every pump seal. FKM is common in many industrial pumps but can be attacked by some chemicals and steam. EPDM is not suitable for most mineral oil and hydrocarbon services. The seal face pair must also match the lubrication and abrasive conditions. Send the fluid type, concentration, and temperature range so we can check compatibility.
Replacement seals are quoted by dimensions, materials, and operating conditions. CORASEALS does not claim to be an authorized distributor for OEM pump or seal brands. When you send an existing seal drawing or type code, we check the shaft diameter, seal chamber bore, axial space, face material, elastomer, and metal part grade.
Do not rely only on seal type codes from old drawings. Some type codes are not consistent between manufacturers. A photo of the seal face, seat, spring, and housing is useful. If you do not have a drawing, send clear photos of the old seal, the pump shaft, and the seal chamber.
Send the following information for a specific quotation:
If the pump runs under vacuum, cavitation, or dry start conditions, include that information. If a barrier fluid or flush plan is used, state the plan and the barrier fluid. Vacuum, cavitation, dry start, barrier fluid, and flush plan details affect seal face lubrication and material selection.
To compare options for your pump model, view our pump mechanical seals or send the duty data through our supplier inquiry form. Include the required quantity and any photos of the failed seal. We will check the data against our mechanical seal range and reply with a specific quotation.
Can CORASEALS supply replacement pump mechanical seals from a drawing?
Yes. Send the existing seal drawing, pump model, shaft diameter, seal chamber dimensions, fluid, pressure, temperature, and speed. We check the drawing and materials before quoting.
What is the difference between a cartridge seal and a component seal?
A cartridge seal is pre-assembled on a sleeve and can be installed without measuring and setting the seal face spring load. A component seal is installed as separate parts and requires careful setting of the seal faces on the pump shaft.
What materials are used for pump mechanical seal faces?
Common pump mechanical seal face materials include silicon carbide, tungsten carbide, carbon graphite, and alumina ceramic. The correct face pair depends on fluid lubrication, abrasives, pressure, and speed.
Do I need to send the pump model or only seal dimensions?
Seal dimensions are required, but the pump model helps us check seal chamber limits and typical duty conditions. Send both when available. If the pump model is not known, send the shaft diameter, seal chamber bore, seal chamber depth, and photos.
Can CORASEALS supply double mechanical seals for chemical pumps?
Yes. Double mechanical seals are available in back to back, face to face, and tandem arrangements. Send the pump model, seal chamber dimensions, fluid, pressure, temperature, speed, and any barrier fluid details.
