This is what we have learnt about fitting hydraulic seals into our pumps. They will be relevant to most other hydraulic equipment. We will add to it and are always happy to receive feedback. Contents: Three tips for easy hydraulic sealing before you start. Things to beware when you’re stripping hydraulics down! Our five big [...]
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 [...]
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 [...]
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 [...]
Why doesn’t my bike have a stepless automatic gearbox? Hydraulic, of course. And a bigger lesson for designers. Sarum Hydraulics are passionate about hydraulics and any application for miniature systems that can do a job better. So why does your bike not have a nifty automatic gearbox that does away with changing gear? A stepless [...]
For a generation who sat glued to the blockbuster “Towering Inferno”, the world has fallen in love with skyscrapers. The developing world is full of them and globally there are now over a thousand buildings with more than 40 floors. Dubai alone has over 170 buildings in excess of 150 metres high! Skyscrapers in Dubai [...]
Sarum Hydraulics were cheered to see a hydraulic drill bolted on the back of a reindeer sledge for a rather sensible way of taking ice cores in the Arctic. Being December, our thoughts quickly turned to Christmas, and how we could give a tech makeover to Santa’s dashing, if not slightly archaic, sleigh. The old [...]
Sarum Hydraulics explores the twists and turns of hydraulics in the amusement industry. With so many white-knuckle rides available for the British thrill seeker at theme parks across the country, a rather autumnal Sarum Hydraulics reflects on the enduring popularity of the local travelling fun fair. October in Salisbury in Wiltshire and the bright lights [...]
