Pressure Test and Hydrotest Hand Pumps. Essential tools for safety and integrity in critical pressure systems. So much large scale infrastructure for industrial processes relies upon vessels, pipework and key pressure components. If there is a failure under pressure, the operator has to face the consequences of safety for staff and the wider population, security, [...]
Pick the right application and a miniature hydraulic system will be perfect for you or your customer. It can provide a dedicated hydraulic system for your specific task rather than sharing a complicated system, have a very small space envelope and can be incredibly cost effective. After 40 years, we have seen how our customers [...]
Making sense of eco hydraulic fluids, synthetic fluids and water in the search for alternatives to mineral oil Are pure water or vegetable oil the perfect eco hydraulic fluids? So, can I run my eco hydraulic system on vegetable oil? What about running my hydraulics on water from the tap? [...]
Passionate about manual handpump solutions in 1982 and now. Tony Foster testing an early prototype. In 2022, our Micropac pump was 40 years old. Yet, despite its age it has remained almost unchanged in all those years and it still sells throughout the world. What need does our Micropac hand pump fulfil? [...]
UKEX and ATEX - a tale of two markets We outline below our understanding of how Brexit has affected selling equipment for use in potentially explosive atmospheres within the UK and the EU. A potentially explosive atmosphere Following Brexit, it became clear that two parallel conformity assessment programmes were going to be necessary [...]
Skydrol aerospace hydraulic fluid is fire resistant and retains a low viscosity at the very low temperatures at altitudes of 10,000 metres and higher. Both are big things for aviation and aerospace. It is used in aircraft hydraulic systems in place of hydraulic mineral oils. For example, the braking [...]
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 [...]
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 [...]
Proof testing versus burst testing: what is the difference? It is important to decide what your objective is, as pressure or proof testing is not the same as burst testing. Pressure testing Pressure testing, proof testing or proof pressure testing: What should appear on my proof testing certificate? In truth, these could be considered different [...]
