When you cannot take chances, 316 stainless steel hydraulic hand pumps are your first port of call. What sort of people use stainless steel for their hydraulics systems and their dispensing, testing and filling pumps? When do you need 316 stainless steel? When is the combination of materials in a pump an issue? I would [...]
Just a simple round up from what we have learnt about seal materials over thirty years. There are no end of sites on the Web on seal materials and compatibility. There are manufacturers like Parker on www.parker.com . There are lots of great distributors. As usual, feel free to comment, even if something is wrong. [...]
After thirty years of manufacturing our Micropac pressure and hydrostatic test pumps, we know a thing or two about leaks. The easy job is pressure testing your job up to a “proof pressure”, checking that it does not leak or has not permanently deformed and signing it off. Job done! The science is in diagnosing [...]
If you need to pressure test, Sarum Hydraulics knows how to do it. We've condensed our knowledge into one easy guide, so you can test equipment easily and safely. Read on to make sure you're pressure testing correctly. 1. First thing is to get people to agree on pressure, fluid and "acceptance criteria". The specification [...]
A Micropac pressure test or filling pump is a mighty useful tool. It inherently has a much greater fluid capability than most units as long as you keep a few pointers in mind. A Micropac is designed for a wide range of fluids. Our pumps cope with a massive range of viscosities because we use [...]
A hydrostatic pressure or proof test is a very blunt tool. Pressurise it up to a factor in excess of working pressure and check there is no leakage or deformation which would indicate design, manufacturing or safety issues. Unfortunately, our experience has been that a blast of high pressure is not the miracle tool if [...]
Manufacturing hydraulic pumps is demanding. We know. We have been at it for 30 years. The five hydraulic workshop products that I personally think make life a whole lot easier are: 1. Ultrasonic cleaner. Forget the watchmaker units, although I am sure they do the job for small bits. For pump bodies and larger components, [...]
