Centrifugal pumps

GREENPUMPS GPC Sealless Plastic Centrifugal pumps are designed and fabricated for medium duty applications.

GPC pumps are fabricated from solid extruded bar and block 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.
