cobble up working stuff, but not a good feel for everything that's out
Can any of you tell me what's the quietest hydraulic motor/pump type?
I'm assembling a "line shaft" system of hydraulics to operate several
machines off a common power source in an environment where electricity
becomes impossible. We cannot bring together all the right characteristics
for a hazardous location electric motor in a single motor to meet all of the
requirements of the environment. So, instead, I'm going to build up a pump
supply that feeds all the machines - one or all at a time via selector
valves - kind of like an old line shaft setup. The electrics will be
outside the building.
I'd rather it be as quiet as possible. I know there are
snubber/suppressor/muffler rigs for gear pumps, but my experience is that
gear motors make a lot of racket, too.
I don't need a lot of pressure or flow. The largest motor we're replacing
is only 1-1/2HP.
