Pump and process seals built to API, DIN and ANSI standards, from single-spring component seals to double cartridge and reactor seals, plus the support systems that keep them running.
Featured
Component mechanical seals for pumps and rotating equipment. The range covers single spring (SF 110/120), conical spring (SF 210/220), multi-spring (SF 510/520/530) and wave spring (SF 710/720) designs, non-clogging, easy to install in any pump, available in balanced and unbalanced configurations.
Elastomer (rubber) bellow mechanical seals: SF 310 to SF 350 series. Close-type, self-adjusting and compact designs for water, chemical, pulp & paper and general process pump applications. Each series is engineered for a specific duty, from large-series cold water pumps to confined spaces and hot water.
PTFE (teflon) bellow mechanical seals: SF 410/420 series for highly corrosive fluids such as salts, acids and organic compounds. Externally mounted, unbalanced seals, independent of rotation direction. All surfaces contacting the liquid are made of chemically inert materials.
Metallic bellow mechanical seals: SF 810/820 series for corrosive, abrasive and viscous media. Self-cleaning and non-clogging construction, externally mounted balanced designs, independent of rotation direction. With selection of special bellow material they can be used in highly corrosive media.
Standard cartridge mechanical seals: SCX 10/20 and SDX 10–40 series. Pre-assembled units for easy installation and durability, ideal to convert and retrofit pumps with packings. Flushing and cooling systems available on request. Balanced seals, independent of rotation direction.
Double mechanical seals with API plan configurations: SFAP 1000 to SFAP 7000 series. Inside and outside mounted designs with leak-proof technology and corrosion and wear resistance using carbon, silicon carbide and tungsten carbide. Extended service life with energy-efficient performance.
Agitator and reactor mechanical seals: SA 100 to SA 700 series for side and top entry agitators, vessels and mixers. Outside mounted balanced designs serving SS/MS type reactors under vacuum and pressure conditions. Capable of dry running, independent of rotation direction.
OEM replacement mechanical seals: SGF-1 to SGF-5, SFH-1/2, SFI-1, SID-1 and SAL-1/2 series. Mono flow balanced designs with single spring and bearing, specially designed for soft and hard water. Different seal facing options (SiC, TC, Carbon & Ceramic) depending on application.
Engineered and custom mechanical seals: SEC 100, SET 100, SEL 100 and SES 100 series, designed and built to customer requirements. Available in different housing materials, shaft materials and connection options with seal facing selected per application.
FAQ
We manufacture component seals, elastomer bellow seals, teflon bellow seals, metallic bellow seals, standard cartridge seals, API plan seals, agitator/reactor seals, OEM replacement seals and engineered/custom seals in balanced and unbalanced configurations.
A double mechanical seal consists of two sealing faces arranged in series, providing an extra layer of protection against leakage. It is used in pumps, agitators, mixers and other rotating equipment where high-pressure, hazardous or abrasive fluids are involved.
Our double mechanical seals feature leak-proof technology, corrosion and wear resistance using carbon, silicon carbide and tungsten carbide materials, high pressure and temperature tolerance, extended service life and energy-efficient performance.
We provide thermosyphon systems, forced lubrication systems and mechanical seal support systems to ensure optimal performance and longevity of mechanical seals in demanding applications.
Our seals serve chemical processing, petrochemical, oil and gas, fertilizer, pharmaceutical, power generation, textile processing, water and wastewater, food and beverage, pulp and paper, and sugar industries worldwide.
