Regenerative turbine pumps

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

GPT pumps are fabricated from solid plastic materials to resist internal and / or external corrosion.

Heavy walled, machined construction provides greater resistance to permeation and migration of corrosive. Additionally, the strength and thermal stability resists deformation, even in the most severe 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 GPT Plastic Centrifugal Turbine pump can maintain design head and flow for an extended running period.

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

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