The pump is a new patented technology!
It utilizes the energy of water flowing through in the drain to elevate incoming water, effectively operating as a hydraulic lever. The expression "down the drain", is effectively utilized by connecting the drain to the pump.
Each time the volume within the pump housing is exchanged, the pump change between lower or upper siphon. Source water is drawn upward while water from the container descends, with an efficiency of up to 90%. The pump housing functions as a water exchanger.
If the operational principle is unclear from the video, please refer to this simple 2D animation illustrating piston dynamics, our 3D animation, or review the explanation of how a switching siphon operates as a Zero Gravity Pump. For guidance on pump dimensioning, please visit this page.
The valve is a new valve technology, and patent pending!
The valve is a zero-pressure operated valve. It has a solenoid connected between the outside piping, and inside the pump-housing, ensuring that the pressure over the valve is equalized before operation.
Since the technology have a lower valve on the other side of the pump housing, this valve will hold the pressure after equalization, so that the valve operated can operate freely.
This ensures a high speed, low energy operation of the valve.
If the operation is not understood from the video, please read how the valve operates to achive a zero operational pressure and very fast acting motion, or have a look at the calculations here!
The piston version is a simple and cost-efficient design.
Piston-operated pumps haven't been widely used for quite some time due to the greater efficiency of centrifugal pumps. However, for the Zero Gravity Pump, this design does not present any significant disadvantages, aside from a slight efficiency decrease in the linear actuator.
The piston version of the Zero Gravity Pump features an aluminum-extruded housing that integrates both inputs and outputs, ensuring cost-effective production.
The energy consumption of the piston and actuator is straightforward, and you can review the calculations here!

This is the first pilot, proving the patented technology with off-the-shelf products and customized tanks.
The operation show how we move 400 liters a minute, through DN100, up 2,3 meters at only 66 Watt. Normal operation for a traditional pump would use 250 Watt.
The only friction forces are from piping, and not gravity. The number of 90-degree bends are stealing efficiency. With no bends, the friction would be lower than 5 millibar, and the energy usage around 10-30 Watt.
The interesting thing with this pilot, is that if we increased height (pump-head) to 10-20 meters the friction would not increase much, and the energy usage would still be very low.
