Slurry Piston Pumps?

[Blue.]

A few on here have them,what sort of money are they?

Found a chap in Ireland making and selling them but his communication skills are somewhat lacking,I’m after one to feed a separator then when I build a new lagoon use it to pump into it a night.

Please can you share your contact as I’m looking to pump sandy slurry from a new shed.
I just remembered I contacted GEA a couple of weeks ago about one, but I’m obviously not worthy!
Welcome back btw.

Piston Pump for Manure Handling - LJM - Lind Jensen Agri

LJM’s piston pump is suitable for animal housings where the slurry needs to be pumped efficiently over longer distances.

I think midland slurry sell Ljm.

I don't know how long a scroll pump like that would last. It is another option however as we dont uses sand.

The other type is a lobe pump.

I tried to use a lobe pump to pump slurry self priming etc only thing was if pipe ever twisted etc it would split the welds on fittings as its a positive displacement pump
If slurry goes in it comes out what ever
Stoped using it when slurry went over a shed roof and covered the farm house back in the 80s

Both progressive cavity and rotary lobe pumps do not like grit or small flint. We changed a rotary lobe on the digester that was using a pair of rotors every 3 days for a piston pump 9 years ago. A set of seals last over a year. It has done 34,000 hours now. Since fitting autolube the flapper shafts need new bushes only every 4 years rather than every 2.
As installed - we have a 2 cylinder setup for steady flow. We changed the swash plate hydraulic pump for a gear type to get the flow for parallel operation of the hydraulic rams rather than the original series.

More recent top view after some changes. We changed mechanical valve switching to electrical, which is much more reliable and gives us full stroke on both cylinders.

I have a gea piston pump, it is very good and the only real issues have been stuff that shouldn’t be going through it (collars don’t fit) and we have had some wear on the one way flaps but only after 5 or so years. If I remember right it was about £11k. If I needed one I would buy another tomorrow.

I haven’t looked at you location but a call to Redlynch engineering near Bruton, Somerset. Much of the kit seems to be imported to them ( I not sure of the arrangement with gea) I have experience of gea themselves not being good at communicating.

Redlynch also sell mavasol pumps but I don’t know anything about them

I rang the local Milfos rep, he explained they had passed the GEA slurry business to Redlynch. Waiting for a quote, I’m thinking that the piston pump may be overkill for me, transferring slurry from a 100 cow shed to the adjacent slurry store.

If you have a GEA, the plastic bits on the flappers do not last well. We have cut new ones out of old conveyor belt, these last much longer. To make them easier to fit, we have threaded out the UNC holes in the flapper to M10, and put M10 set bolts in the holes so there is something to aim for with the new rubber, the keeper plate and the M10 nuts when you are feeling inside the pump.

We keep a spare base with flappers for service exchange, and fit generic bushes and O rings to new 1" shafts when needed. We also fitted hydraulic fittings to the flapper shaft greasing holes for easy hose removal, and threaded the 1/4 and 1/8 NPT male threads down to BSP. Male BSP seats OK in NPT female, but male NPT does not go into female BSP nicely.

If you are on sand I would go for it. It may be overkill but they just work. One pump every 20 seconds.lazer level switch in the collection pit and it’s all automatic. Occasionally we have to prime it but that is more to do with the separator than the pump.

What sort of kw’s power pack do you need to run it?

Did it have a reciprocating valve?

I would have thought a reciprocating valve would have meant you got a full stroke every time.

The shuttle valve gave a full stroke on the cylinder it was attached to, but the second cylinder ran at gradually reducing stroke. There was a relief/check valve thing which was supposed to compensate, but it did not work reliably. We are now using a 5.5 kW pump/motor set, the original was a bit smaller. If I was buying again I would probably get it without the hydraulic power pack, and get one from Flowfit to suit.

Your on the same wave length as me,buy the pump and plumb it up myself.

I don’t want fancy cabinets with pcb’s just a simple system that I can keep going myself.

For a single cylinder, no problem with mechanical controls. It is the twin cylinder that works better with the electrical control system. If you are running it for a significant number of hours a day, then I would recommend an automatic greasing system to avoid wear on the shaft, otherwise just keep it greased regularly.

So the wearing parts are the shaft of the flappers?

Seen a fair few with knife type gate valves instead of flappers,I suppose flappers cops with foreign bodies better?

What’s the water pipes on your inlets for?

Wearing parts are the lip seals for the pistons, and the flapper shafts and bushes. We run old oil on top of the pistons. Gas engine oil bypasses the seals faster than diesel engine oil, but the slowest to be used up is used vacuum pump oil.
We have pumped 4" diameter flints, gate hinges, all sorts! I have a large collection of scrap metal which has been scraped up with the slurry and gone through.
One water pipe is the whey feed to the digester, the other is to back-flush solids blockages in the solids feeder if that blocks.

Just waiting for mine to arrive, bought a Dari tech from mavasol in holland, they have a uk dealer but direct was much cheaper, think they would sell it to you with no power pack, I will be doing the control system myself, they were cool about it, 12-13k from memory

 

[sjt01]

I would be interested to see what you come up with for a control system. I have an upper and lower proximity sensor on each cylinder, a Mitsubishi Alpha controlling the solenoid valves, and the hydraulic pistons plumbed in parallel rather than in series.
