Regenerative turbine pumps

GREENPUMPS GPTA Sealless Alloy Centrifugal Turbine pumps are designed and fabricated for low flow and high head applications.

All GREENPUMPS, due to the construction features are thought to have zero leakages even in extreme working conditions.

The absence of mechanical seal or packing gland eliminates dangerous emission in order to protect the environment and workers.


GREENPUMPS GPTA Alloy Centrifugal Turbine pump can maintain design head and flow for during an extended running period.

The multi-vanes self-balancing impeller construction eliminates the thrust loads and can be started with completely open discharge valve.

GPTA are suitable for thin non-lubricating mediums with a very low NPSH available value.
