    Electronic ballasts for fluorescent lighting

    Question: are all electronic ballast equal? I guess not but maybe someone here can tell me what's going on with my setup. In my work I shoot high frame rate digital video up to 1000 frames per second. At this framerate flickering can ruin my work. Ordinary fluorescents with magnetic ballasts...

    Sonic pulverizer

    Is anyone familiar with the use of a standing sonic wave to pulverize the solid content of a liquid stream? I remember reading years ago about sonic cavity design that, coupled with a sonic transducer, could create thousands of pounds of sonic pressure. Ring any bells?

    Pump filter

    I have a recurring failure problem with the packing on a high pressure pump. The fluid is pretreated with iron salts in an upstream process. The fluid is then screened to 1 millimeter but I suspect that some fines are getting through and ruining my seal. The pumping cylinder is made of...

    Soft starter

    I’m currently designing a commercial version of a high pressure pumping system. This is a scale up project. I currently have a single pump with a 125 hp motor. The pump came with a soft start and I use it to limit the startup current to 180 amps. I am now scaling the system up to 6 pumps...

    Flow Temp and Pressure in one instrument?

    I've seen these but I don't know where. My specific needs are 0-50 gpm, 50-150 degF and 0-100 psi. 2" pipe connection would be perfect. Thanks

    Hi Pressure stuffing box

    I thought I’d start a new thread to get a little education into packing and stuffing boxes. I have very little experience in the use of packing. I’ve always used mechanical seals wherever possible but this is a reciprocating pump with no other option. In our process we use a 3 cylinder pump...
