Does anyone recognise the make and model of this pump:

It's driveable from both ends, one end with the pulley, the other from a standard 6 spline PTO which is what I'd use. From the piping, it looks like it can be driven in either direction, and I'm hoping that one of those domes contains a pressure relief mechanism in case the discharge valve gets closed.

It's for sale a couple of hundred km's from where I live. The owner says in his advert that it's "as good as new", but he might just be referring to the coat of paint...

It's capacity is "gigantic", but before I go to see it, I'd like to find some slightly more technical info on it such as delivery volumes & pressures, and power needed to drive it. See if it's suitable for what I need. I emailed the owner, no answer back so far.

Ian,
It looks more like a agriculture pesticide sprayer pump
to me, diaphram stlye.

is a quick pix I found of one, probably not exactly what you have there.

Thanks Doug,

Yes, that looks very much like it; I was assuming it was a rotary vane pump, but I think you're right. The diaphragm pumps that I've worked with have all been the Wilden pump types, driven by compressed air - I didn't know they also came in that configuration.

But that'll do fine. I want to be able to throw a suction hose into a pond, fill an IBC and then pump from the IBC to a hose for watering trees, and this type of pump looks to be fine for that service. It'll be self priming (the seller mentioned that too) and pretty tolerant of pumping a bit of mud, tadpoles etc.

I just *love* this forum!

It looks like a radial diaphragm pump. They use these for sewers, septic tanks, and such, because they're not hurt by running dry or sucking up a little trash, so it ought to be just right for a pond if that's what it is.

Yep, that's what it looks like. It was so close to the pic that Doug found, that I emailed Hypro pumps. Sadly, it's not one of theirs, so I'm still trying to find the manufacturer. I'm liable to need some spares.

I'd like to drive it with a minitractor (about 20Hp or so). Shouldn't be a problem, as I'll only be lifting water about 2m and won't need that high a discharge pressure (how much backpressure do you get when you put your thumb over a hosepipe?).

I don't think the diaphragm will last very long.

Depending on the price he's offering, this little pump (http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=66585) give you the same rough capacity and is spec'd for solids 11/64' for a reasonable price.

Bill,

The reason that I didn't want a centrifugal pump (like the one in your link) was that they are generally not self priming. I'm also after a pump that'll run from my tractor's PTO shaft.

Centrif's are certainly tolerant of dirt - but I'm hoping that most of what I pump is fairly clean - hence the use of a vane or diaphragm pump.

We use air driven diaphragm pumps offshore for cleaning sand out of vessels - typically, we'll pump 10 tons of sand & other bits of rubbish out of a vessel in an oily, watery slurry. The pumps never seem to complain.
