Sliding vanes pumps

GREENPUMPS GPA Sealless Sliding Vanes pumps are designed and fabricated for constant low flow and high head self regulating applications.

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

Absence of mechanical seal or packing gland eliminates dangerous emission to protect the environment and workers.

Specifications

GREENPUMPS GPA Sliding Vane pump can maintain design head and flow for during an extended running period because of self-compensating carbon vanes.

GPA are suitable for thin non-lubricating mediums eliminates pressure drop and without rapid wear of carbon parts.
