The patented line (EU1370506) that changed sealing: no shaft sleeve, self-cleaning tapered stuffing box and monolithic sintered faces. Fits where a cartridge seal was impossible before and multiplies MTBF on slurries and dirty fluids.
Single sleeveless cartridge seal, patent EU1370506. Tapered box, hydraulically balanced monolithic faces and damping elastomer. Extremely compact design.
Double sleeveless cartridge seal with bidirectional pumping ring and multiple springs out of the fluid. Withstands radial misalignment up to 5°.
606 variant with single spring absorbing axial play up to ±10 mm. For vacuum pumps, reactors and heavy-duty mixers.
Split sleeveless seal: both halves come pre-assembled and simply join together. Virtually eliminates installation errors. Also available semi-split.
No wetted metal parts: wetted components in sintered silicon carbide. A better, cheaper alternative to Super Duplex or Hastelloy C276 in aggressive chemicals.
Double version of the NMT technology, designed specifically for aggressive and hazardous chemicals.
Reinforced heavy-duty version for shock loads: oversized drive and anti-rotation pins, reinforced multiple springs and external quench ring.
HD + NMT combination: the ultimate solution for heavy abrasive slurries typical of mining and pulp & paper.
High-pressure variant, up to 1450 PSI (100 bar). F.E.M.-designed faces working without distortion at extreme PV factor.
Specific execution of the Style 600SL. Ask us for the dimensional chart to check the fit on your pump.
New concept in double cartridge seals making the best use of the Style 600SL technology and widening its applications. It carries its own conical stuffing box extension for the longest possible MTBF. Double floating seal with multiple springs out of the pumped fluid: extremely compact and able to withstand radial misalignment up to 4°. With its standard pumping ring it installs in almost every application, even heavy-duty pumps, reactors and mixers.
Complete range of Style 600SL seals specifically tailored for slurry pumps. Thanks to the conical design and its compact dimensions it integrates inside Warman* pumps within its own stuffing box, mounted directly on the pump body: no modification and no adapter required. Heavy Duty arrangement also available. For pumps already fitted with a cartridge seal adaptor, Style 600HDS and 600HDSQ can be used instead.
Sleeveless seal integrated inside the stuffing box of Metso* horizontal slurry pumps. Also available in Heavy Duty arrangement for particularly dense fluids; diamond-coated faces are suggested for low-lubrication media.
Sleeveless cartridge seal designed to fit and operate in Moyno/Mono* Series 2000 positive displacement pumps, whose available space would normally prevent a standard cartridge seal from being installed.
CVD diamond-coated seal faces: they greatly outperform other materials in friction, heat generation and dissipation, power absorption and dry-running tolerance. Although not intended for continuous dry running, they remove the risk of damage from occasional lack of lubrication, and the energy saving usually exceeds 50 % of the seal's consumption. Available as Standard (8 µm layer) and Heavy Duty (16 and 24 µm).
