GREENPUMPS – Thermoplastic GPM Injected Moulded

GPM Injected Moulded


GREENPUMPS is specialised in the design and application for water treatment, pharmaceutical, chemical, petrochemical and refinery applications. We continue every day to lead the way providing the most reliable sealless pumps available with the latest technology.
All GREENPUMPS sealless equipments are engineered to comply with the new environmental rules “1990 EPA Clean Air Act”. Our mission is working for the future giving “zero emission” to preserve our environment.


GREENPUMPS GPMSealless Plastic InjectedMolded Centrifugal pumps are designed and fabricated for light duty and transfer applications.
GPM pumps are fabricated with plastic injectedmolded technology to resist internal and / or external corrosion. Pump materials filled with fiber glass or fiber carbon are designed to handle difficult solutions such as strong acids and difficult chemical compounds in chemical, OEM or industrial 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 emissions in order to protect the environment and workers.


GREENPUMPS GPM Plastic Centrifugal InjectedMolded pump can maintain design head and flow for an extended running period.
