Small engine driven water pump.

[Agri Spec Solicitor]

Help please. We once hired a water pump with a little petrol engine. Great in water when emptying a big hole but when the water became silty it could not cope. That’s all our experience.
Current plan is to use pump to move silty water, clean water, and possibly septic tank contents. When jetting it needs the capacity to fill a 1000l IBC before we get bored too much.
Nearby I found a 3 inch Koshin. SEH-80x lightly used, Honda engine. Then there are lots of hose options. There are many to choose from and wondered if anyone had any suggestions for our application based on actual experience.
I don’t want a diesel engine. Honda preferred. Any help appreciated.

Is there a machine that will pump…
Clean water
Silty water
Septic tank contents which can be a bit stiff

I bought a 1" petrol pump this week with a Loncin engine, brand new it was circa £150. Happy to use it for clean and dirty water, it only struggles if the suction filter gets clogged.
I also have pretty much the same but 2", same make of engine and had it years. Cost less than the new one back when I bought it. Abused and neglected and still works well.
Wouldn't use either in a septic tank though, they require sucking out with a vaccy tanker in my opinion. You only do it to desilt them so not really what a pump can do.
Personally I wouldn't go bigger than 2". They pump plenty fast enough and a 3 inch sucks too much to the point that unless it is in a pretty big river it runs out of water too quick.
My 2" pump will fill an IBC in less than 2 minutes, that is plenty quick enough.
Everyone I have ever spoken to has said the cheap Chinese pumps last forever, I wouldn't pay the extra for a Honda. Glad I didn't

You need a vacuum pump and tank for that job, surely?

Thanks for the above posts. The septic tank idea is just that we have 2 sealed tanks on the caravan site. If it all went wrong and waste people were slow I thought we could maybe transfer between the tanks so that one did not overflow. If that isn’t possible it is no big deal. Main job will be filling IBCs from a trough. The Koshin is Japanese. Looks like the 3 inch is the wrong model. Honda engines have been so good for us over many years I wouldn’t go past them.

In a pinch, beg/borrow a farmers vacuum tanker.

Honda wb20xt ( 2”)moves 15000 litres rain water to my spray tank in about 30 minutes from an underground tank to an above ground enduromax tank. The pump is sucking between 1 to 3m and pushing water 25m horizontal before going up 4m to the tank. There is a one way valve and sprayer suction filter basket on the end and I have a fine filter on the spray tank outlet. Very little sediment is caught by the final filter although there is plenty of mossy sludge in the bottom of the suction tank. I think Honda do a range of sludge pumps as well as water pumps.

When my septic tank needed emptying, I hired a sludge pump from a local plant and machinery hire place and pumped the sludge into the nearest field. It stinks for about 24 hours and then the sludge disappears, same as FYM. Perfectly legal so far as I am aware so long as it's your own sludge disposed on your own land. Can't remember what engine was on it but the whole unit was reasonably man handle-able and it didn't cost a fortune.

Did the same thing in the Hebrides where there was no tanker. Dug a small track down to the sea (all down hill) and pumped it out with a man with an oar giving it a good stir. He reckoned he'd finally achieved his true vocation!

A septic will pump out with an electric sump pump if it's a one time thing, or a sewage pump if it has to be reliable. That koshin says "clear water" and has no max solids size, so no septics for that. Silty water isn't the problem, or even sewage, it's the long fibrous stuff that finds it's way in to plug the impeller or screen.

I have a Honda trash pump, didn't buy it new, but if I needed a reliable one I would pay more for the quality and attention to detail. The easily removable pump cover is worth it if you need it.

You want a trash pump.

They're easily identified by having big knobs on the pump housing to let you quickly open the pump housing to remove "blockages,"

Working on a new Honda WT20 which should do the job and it is completely a Honda product, not just Honda powered.
It will weigh about 50kg fuelled up which is a heavy lump.
Anyone got an idea for easy movement in fields? All I can think of is strapping it to a boarded pallet or ATV trailer.

If you could put up with 240v mains ??? Vortex 100 seem to be quite reliable in parlour pits, cess pits etc.
They seem to handle quite thick stuff. Cow clogs will beat them tho....
Always fit a proper overload (not a 13a fuse) will save a motor if it jams.....
Outlet/inlet 1.5" so may be a bit small for you.........
