Light. The immediateness of maintenance operations calls for solutions that guarantee optimal functioning in the most unfavorable conditions.  The new clamp HERMETICA S500 Series enables you to carry out maintenance operations in a fast and easy way, thanks to its ‘Hold-in-Place’ y ‘Pilot’ systems. As you can open it completely, you can repair without cutting the pipe, therefore reducing the time to establish water supply.

Simple. Maintenance operations require solutions that are a 100% adaptable. HERMETICA’s 100 Series, with a width of 135mm, adapts to repairs in a confined spaces. With 70mm of usable width, it can repair any crack or leakage on pipes of any material and pressure rating, as well as substitute broken joints in just a couple of minutes. Installation time is reduced in a fast and easy way thanks to its ‘Hold-in-Place’ y ‘Pilot’ devices.

Versatile. Wide tolerance range to solve repairs with angular deflection, deviations, offsets and differences in the pipes’ outside diameters. The possibilities of adaptation offered by HERMETICA’s 2000 Series enables you to solve the most delicate maintenance issues with a warranty of success. Available for pipes of any kind of material, with a tolerance range of up to 16mm. Installation time is reduced in a fast and easy way thanks to its ‘Hold-in-Place’ y ‘Pilot’ devices.

Robust. Situations of high requirements on critical points within the water mains demand for exceptional reliability. The new HERMETICA High Pressure pipe repair clamp, ( Serie AP)  is the answer designed by the R&D&i department at DHSF, based on years of experience in the sector: a unique design n the market that assures maximum performance under conditions of extreme pressure requirements. With work ranges of up to 40mm of tolerance and pressure ratings of up to 40 bar. Installation time is reduced in a fast and easy way thanks to its ‘Hold-in-Place’ y ‘Pilot’ devices.

Reliable. Mining, chemical and oil-processing industries handle fluids at high pressure. The new solution for fast and reliable maintenance designed by the R&D&i team at DHSF guarantees to reduce the time needed for maintenance and bringing operations back to service.

HERMETICA stainless steel clamps are certified under European manufacturing regulations. Our production range from 60mm to 4.000mm enables us to give a reliable and tight solution to any kind of pipe network. In difference to joints with a plain or waffle type gasket, HERMETICA’s lip design creates progressive sealing off, using the pipe’s internal pressure. Therefore, HERMETICA offers warrantied service at 6, 10, 16, 25 and 40 bar, even in situations of water hammers and excess pressure.

Facilitates fitting. Reduces installation time.

Installation of branches and connections. Eases axial and radial tensions in both directions of the pipe´s axis.

Installations of reductions. Allows for axial expansion actions and contraction caused by variations in temperature.
