Very short synopisis of presentation for non German speakers:

Former ship captain came to his passion for pumps when his ship needed a pump and there was no way to source one in time. He put something together with parts available to him.

Supposedly has customers lined up in Scandinavia.
Delivery time 4 months.

The wheel drives an electric motor which runs the pump.

It takes a manual start and from then the wheel just runs.
He's been working at this for 30 years, the other gentleman has been helping out for the last 2.

(Patent from 2012 attached)

Basic Google translation from German document:

(54) Designation: Rotary vane pump (57)

Summary: The invention relates to rotary vane pump (6), which comprises a housing (1) with a rotary vane rotor (3, 12) mounted on both sides in the housing (1), in which radially to a rotary axis movable lamellas (10) in the rotary vane rotor (3, 12) are arranged, which are arranged between an inlet (7) and an outlet ( and a rotary vane rotor outer wall (9) and a Rotary vane rotor sliding surface (13) of a perimeter wall of the Housing (1) form a pump chamber (11). It is provided that the rotary vane rotor (3, 12) has rotor transport chambers (17; 17A-17H), which form as a pump chamber (11) a rotor and lamellar clearance (2) for transporting a medium.

Description The invention relates to a rotary vane pump having the features mentioned in the generic term. Circulating pumps, including so-called rotary vane pumps or vane pumps are known. Rotary vane pumps have a rotor, the essentially radially movable rotary vane has. The sealing valves are mounted individually and are guided independently of each other in the rotor. The sealing vanes (fins) are either supported by centrifugal forces or springs, here in this case by rings, where through them on a perimeter wall of a pump housing by Forced control can be pressed and thus be able to absorb vacuum. The pressure and volume flow is caused by the fact that the lamellae form closed chambers and thus transport the entire liquid volume with pressure increase from the inlet to the outlet.
For rotary vane pumps, the forces transmitting the rotary vane to the rotary vane rotor and thus to the drive shaft is limited by the fact that: the possible force absorption of the drive shaft does not may be exceeded. Lower speeds with At the same time, high conveying capacities and conveying pressures, whereby an energy-saving conveyance of the Rotary vane pump has already been with the patent EP 1279834, patent holder Hermann Lidlgruber. A further difficulty is the identification of problematic substances, in particular media and the contain a lot of mud, sand, stones and coarse rubbish to pump. Biopower plants, waste recycling for Energy generation urgently needs pumps that are able to transport these media.

The Inventor has set himself the task of creating this Problem to solve, which he has succeeded with the design of this invention. This rotary vane pump according to the invention also has the advantage, to bring a further force input, further higher volume and to transport sand, mud, stones and coarse rubbish and even gentler to pump. The invention shows a rotary vane pump whose rotor consists of one piece with the axis of rotation, centering shaft and drive shaft.
The Rotor has milled rotor transport chambers. Through these large rotor transport chambers, a large volume can be transported, even larger impurities, mud, stones, solid media and also vacuum.
By the chambers, which are represented by the Lamellae are closed, the mentioned media can be conveyed in full height in gentle operation from input to output. The transport chambers have yet another advantage: The slats are pressure-relieved. The pump requires much less energy due to the large pump volume.

1) the pump can transport a particularly large volume,
2) it can transport major impurities and solid media,
3) it works very gently,
4) through the transport chambers are the slats pressure-relieves, which makes the pump resistant to repair.
5) the pump requires much less energy than other pumps.

What I can gather from the document:

Vanes close off the chambers that transport contents from inlet to outlet.
Pump housing radius increases, but the self adjusting vanes seal it off anyway.
Due to expanding volume, a vacuum is introduced.

Might the vertical path after the pump be part of the "trick"
Would you leave the setup as described, letting water cavitate and implode on the way up, or introduce atmospheric air while you have the vacume and the pump running well to seal off against reverse flow?

At 17F, the chamber size is minimized, minimum volume of cavitated water and/or vacuum sent from outlet side back to inlet.
At 17C a larger and still expanding scoop of water mixed with a partial exhaust volume is taken in.
At 17A, the volume is at maximum just before the outlet is reached.

I hope I have that the right way up.

It looks honest....

It's old hat. Look on you tube there are simpler ones than that pumping gallons far up hills
from ponds and Rivers. Most of them are Asian vids, Perhaps we can learn from our Asian
friends.
