for collection in person, without warranty, a choice of 6 W3 pumps in various conditions, from reconditioned to dismantled, for 900.- , so for this particular listing there is a dismantled one for restoration, not a complete one for immediate use
the following W3 are available:
1. green with plug-in liner and motor, belts, valve bridge needs a new screw
2. grey with a plug-in liner without a motor, without belts,
3. green partly dismantled with liner, piston rod stainless steel
4. blasted, primed red-brown, dismantled, with the eccentric complete and piston rod brass, assembly possible without difficulty using small parts
5. blasted, primed red-brown, dismantled, incomplete as the eccentric is defective
6. blasted, primed red-brown, dismantled, incomplete as the eccentric is defective here too

The manufacturer, East as well as West-...: ....probably still supplies operating instructions, valve discs for the suction and pressure side, valve plates, valve springs, leather cups, cylinder section, pressure valve set, stuffing box body etc. You could then overhaul them yourself; there are pre-war Loewe pumps and East (at the old site in Salzwedel) and West production (Lüneburg), here only from Salzwedel, which may be worlds apart, nonsense, the towns are 66km apart as the crow flies, with 100m town hall towers you could almost wave to each other. Naturally the devil is in the detail here too. At least something about the valves. I now have a sectional drawing of a Lüneburg W 2 1/2, they altered a great deal there after the war. West then had separate brass bushings, Salzwedel uses only the grey cast iron of the head as the bushing for the piston, now of course boring out and a new grey cast iron liner as the restoration approach, or polishing out

1st inspection:
in the photos you can see the partly dismantled W 3 offered here, 3 of them, the valves need reconditioning at the very least on all of them, the price refers to 1 unit of W3 including matching motors where available, the first buyer can take their pick, I have 2 motors here ready to hand, I assume 3kW, I read 1x 2.5kW, so possibly run as a W3-10
discovered a gearbox cover with a crack etc.2nd inspection:  there is one connecting rod complete with a very good pinion (photo 4), also at least one brass push rod, 1 connecting rod broken, 1 connecting rod not seen, 2 air vessels Salzwedel No.3, 1x only marked W3, all 3 heads with grey cast iron bushings, so Salzwedel, where sheet metal or brass bushings, or grey cast iron or stainless steel can be fitted after turning if required. All heads free of frost damage. Individual parts are also sold and shipped where possible. Better to come by. Took 1 interior photo of what appears to be a complete, good gearbox (photo 4). Will be uploaded here shortly. The white-green head has run the least. Photo 7 belongs to gearbox photo 2.
3. one pump has now been moved and thoroughly examined, and since I have just built up a W 2 1/2 of my own (a powerful thing, you need some nerve to hold the C hose together with the fire hose nozzle) which fortunately already had a stainless steel liner in it, my eye for detail has been sharpened, everything for an (almost) complete W3 has now been gathered together:
gearbox complete, cylinder section with a worn grey cast iron liner, not to be compared with my W2..stainless steel, this would have to be bored/turned out and fitted with an insert cylinder, a new piston without leather cups is here, the valves have not yet been checked, but since spare valves are on hand it is a manageable job, motor, no 17 1700 belts obtained yet, they are only needed once work on the cylinder itself continues, further costs to come would be: 1 insert cylinder in grey cast iron costs approx. 190.-, including boring out approx. 390.- , 1 of 2? leather cups approx. 27.-, 1 of 3 V-belts approx. 15.- , for now it is my garden decoration, boring out can also be done with a boring mill, a bushing can also be had for around 100.- , if you know the dimensions :-)

the last photo is from the Steffens pump specialist dealer in 33129 Delbrück-Anreppen, they take a W3 like the one I am offering here without an electric motor as a trade-in, so that you can buy a reconditioned one at all (see their photo - green), spare parts are supplied by them as well, other suppliers also deliver spare parts, that used to be different in the East, hence the stockpiling with a partly large collection
These W types have been made by Loewe of Salzwedel since 1930, produced at least into the 1970s; after the war there was also a further developed production in Lüneburg. Please note.

all the following data without warranty, researched as such, you can see that the 2 units of W 2 1/2 previously listed and now sold were similar, list from Steffens..
From a Loewe W 2 1/2 there is still 1 connecting rod here and an axle with the small pinion, the latter already quite pointed, a listing will follow if there is demand, enquiries welcome

see in my shop under Sonstiges, there are several listed !! collection in person only, I already have motors etc. as an alternative bolted onto auxiliary pallets /Euro pallets, then your having a haulier collect this does of course work, but for the time being I rule it out specifically for the W3


data without guarantee:
Piston pump Loewe W 3 rated at at least 10,000L/hr ,300kg, 2 1/2" inch connections for the suction and pressure side,  similar to the  W 2 1/2 and W4, WIII  WIV, smaller and larger differences
It is a self-priming, slow-running geared piston pump.
Restored on the gearbox and water side it is surely a superb piece.
A test run under extreme load unfortunately cannot be carried out on site
even if somewhat elderly, it is the proven old German quality workmanship.
This pump is outstandingly suited, above all because of its high output, even at higher pressure, to tree nurseries, orchards, farmers, so everyone who needs a lot of water from filter wells or open water. But also for transferring and pumping out ponds.
 
the suction pipe really should be 2" across, or an open body of water, otherwise there is no point in connecting this one

the two W 2 1/2 listed here for a long time are both sold and gone. In this listing you can now acquire and collect only a W3

There are further pumps on offer and being listed. But all smaller post-war models. Piston pumps and centrifugal pumps, see in my shop in the category Miscellaneous
