how it works
How does a positive displacement pump work?
The TARUA self-priming lung technology
Understanding how a positive displacement pump works is essential to appreciate the efficiency of the Tarua system. A positive displacement pump works by trapping a fixed volume of fluid and moving it through the pump system during each operating cycle.
This principle allows the pump to maintain constant flow and pressure even when handling viscous fluids, sludge, solids and complex industrial materials.
The TARUA ® pump applies positive displacement principles through its innovative “lung” technology, which is part of the Tarua industrial pumping system.
"FULL-PASSAGE" THANKS TO A "LUNG"....
The TARUA ® pump operates as a reciprocating positive displacement pump designed to handle liquids, sludge and solids through a full-passage architecture.
The large passage, or Flow.Plus, is achieved through the valve and “lung” combination of the TARUA reciprocating positive displacement pump.
The “lung” is the flexible pumping chamber that expands and compresses during operation, generating the vacuum required for suction and transfer of liquids, sludge and solids.
This component was designed and manufactured by IDEE E PRODOTTI using NBR rubber, as it must be flexible and able to withstand the continuous and rapid compression and expansion movements.
Its diameter is sixteen times larger than the valve diameter, allowing large bodies to pass through and guiding them smoothly towards the outlet during the compression phase.
This design enables the TARUA positive displacement pump to transfer liquids, sludge and solids without clogging.
...COMBINED WITH A SPECIAL VALVE.
The TARUA pump system combines the flexible “lung” chamber with a specially designed valve (designed by IDEE E PRODOTTI and named Kodrill) that regulates the suction and discharge phases of the pumping cycle.
During operation, the valve works in synchronisation with the expansion and compression of the lung chamber, allowing the pump to create a powerful vacuum during the suction phase and to guide the material smoothly towards the outlet during the compression phase.
This coordinated movement ensures that liquids, sludge and solid particles can pass through the pump without obstruction, even when dealing with difficult industrial materials.
Thanks to this valve-lung combination, the TARUA positive displacement pump maintains continuous flow, reliable suction capacity and high operational efficiency in demanding industrial environments.
