This cartridge grundfos mechanical seal is a smart design pump seal for grundfos vertical pump, this seal suit for grundfos CR CRI and CRN series vertical water pumps. As a special cartridge mechanical seal, we follow the original grundfos design 100% for this seal, this help to avoid any installation mistake when you install the seal for the grundfos pump, and make installation easy. Our grundfos mechanical seal frame and spring are made by strong quality stainless steel SS304( SS316 available too) material, help to against rusty problem. We use SSIC (Pressureless Sintered Silicon Carbide) as stationary and rotary seal face, it is much better than normal material RSIC(Reaction sintered Silicon Carbide), offer more wear resistance for the grundfos mechanical seal. For Rubber part, normally people choose EPDM or VITON for secondary seal. Our grunfos mechanical seal will make your pump as good as new and reduce downtime, and last longer time when pump running.

Guangzhou Lepu machinery CO., LTD becomes one of the leading mechanical seal supplier in south of china, we focus in designing and manufacturing mechanical seal for many kinds of famous brand pumps, our mechanical seal cover many kinds of industry like food, petrol chemical, paper making, sea ship, and so on.

We have carved a niche amongst the most dominant names in this domain, instrumental in providing an excellent quality range of Split mechanical Seal. Split Mechanical Seals can be installed without disassembly of the equipment, simply attach two halves over the shaft and mount like any other cartridge seal. The only split seal that can be fully pressure tested at the factory before shipping can convert a packed pump to a sealed pump easily.

Type SPT770 is a unique design with minimum components for assembling the seal and allow user to install the seal in minimum time. The finger plate spring design keeps the faces uniformly in contact. The Split Seal face is balanced covered with Split O’ Ring as a sealing member. Slots provided in the housing facilitate fitting the Seal on various Equipment’s with different PSDs for standardization.

Wenzhou Landmark Seal Manufactuing Co,.Ltd is established in 2011, Producing small standard mechanical seals with quantity more than 250000 pcs per month. Our advantage is small seals with all range of stamping and rubber moulds. The production is ISO 9001 , TUV , SGS, ROHS certificated.

Advanced Sealing Technology (AST) manufactures a complete line of cartridge and component mechanical seals for process pumps. The AST 70 single cartridge seal has become the industry standard for harsh applications.

The AST 70 is a simple-to-install, unitized cartridge mounted, balanced, multiple spring mechanical seal which requires no measuring for installation. The seal faces are protected from damage and contamination from dirt and foreign particles.

The AST 80 dual cartridge seal incorporates liquid shear pumping to remove heat from the seal faces, and can be operated with a pressurized barrier or non-pressurized buffer fluid system.

No more waiting for seal repairs, and no more worries about installing exchange seals that might have previously held hazardous materials, because the AST 70 is easy to rebuild on site using standard tools.

AST 70 seals are available off-the-shelf to fit most ANSI pumps, including enlarged bore pumps, without modification. Seals are in stock to fit many split case, positive displacement, and vertical turbine pumps.

AST can design and build special AST 70 seals for vertical turbine pumps, large split case pumps, and other systems that require more than a standard seal. Rebuild parts are still off-the-shelf.
