How picking the right elastomeric hydraulic seal material is more than just chemistry and a catalogue. Use a seal material catalogue Useful elastomer materials What to watch out for Formulations change over time Specialist compounds Shelf life Machined seals Talk to an applications engineer After 30 years, Sarum Hydraulics knows quite a lot about seals [...]
We use these capped piston rod bearing seals extensively. Trelleborg call this type of seal a “stepseal”, although lots of people produce their own versions. Why do we like them? They offer extended life, cope with fluids with poor lubricity and allow you to easily swap the elastomeric O ring that fits under them to [...]
Just like the stepped piston rod bearing seals, we use these capped piston seals extensively. Why? They offer extended life, cope with fluids with poor lubricity and allow you to easily swap the elastomeric O ring that fits under them to cope with a wide range of fluids and temperatures. A moulded seal rarely gives [...]
Why do we like U seals? If you don’t need to offer a wide range of fluids and temperature ranges using one size of groove, a U seal for a piston rod bearing can be a great choice. Pick polyurethane (PU) and you have a remarkably rugged seal. The temperature range of down to -30 [...]
Specifying a standard hydraulic pressure gauge manometer range makes life so much easier. After 40 years, we think we are finally getting to grips with which ranges are standards in what country. We thought we understood it but even now still struggle every time somebody tells us the range specified is not available. Our [...]
How adding smart hydraulic design to seawater desalination and water treatment plant could just carry through a renewables revolution for fresh water from the sea. The United Nations (UN) is very worried about fresh water in its World Water Development report of 2016. There are too many people on this planet and there is [...]
SoftBank Team Japan foiling at high speed. Photograph Matt Knighton How those pedalling Kiwis aren’t the only show in town for innovative pedal power hydraulics. 55mph composite America’s Cup catamarans take hi-tech sailing to the limit The foiling catamarans developed for the America’s Cup are serious engineering in Sarums' eyes. Lightweight composite structures [...]
How Big Hydraulics keeps London running smoothly. What caught our eye from The Shard? The Shard, next door to London Bridge Station, is the UK’s tallest building at 306m and one of the iconic landmarks of London. Opened in February 2013 after four years of construction, its 95 floors house hotels, apartments, restaurants and offices [...]
Hydraulic compression fittings explained. Read our take after 30 years of using single and double ferrule fittings. Before you start. Rigid pipe or hoses? If you want a permanent installation and a neat job, piping it up with tube and compression fittings will give you a “better job.” Debatable? Yes, hoses have a big place [...]
Clever water hydraulics crafts the perfect Espresso. Can a hydraulic process really capture the craft of the barista maestro and produce the perfect espresso? The world loves espresso. The world loves espresso coffee. There are 21,000 coffee shops in the UK alone, so the Allegra Coffee Portal tells us. This article tries to [...]
