Injected moulded plastic centrifugal pumps

SERIES GPM
GREENPUMPS TECHNOLOGY INNOVATION AND RELIABILITY
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 GPM BENEFITS
GREENPUMPS GPM Sealless Plastic Injected Moulded Centrifugal pumps are designed and fabricated for light duty and transfer applications.
GPM Pumps are fabricated with plastic injected moulded technology to resist internal and / or external corrosion.
Pump materials filled with fibreglass or fibre 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 seals or packing glands eliminates dangerous emissions in order to protect the environment and workers.

COUPLING HOUSING

COUPLING HOUSING FEATURES AND BENEFITS
The revolutionary new design of the coupling housing allows IEC and NEMA motor adaptor plate plug-n-play, keeping the same coupling housing, with considerable reduction of inventory costs and improvement of flexibility.
GPM series coupling housing and all the pumps parts are manufactured with injected moulded technology and they do not require any further machining, increasing the pump global quality.
Coupling housings are interchangeable between GPM6 and GPM10 and between GPM15 and GPM30.

INTERCHANGEABLE EXTERNAL MAGNET HUB

EXTERNAL MAGNET RING
REMOVABLE MAGNET SECTORS
EXTERNAL MAGNET FEATURES AND BENEFITS

Last generation external magnet, with neodimium iron boron sectors providing high torque and easy sectors replacement. In case of impact during assembling and disassembling operations, the external magnet inner configuration does not allow damage of magnet sectors and containment shell. The exceptionally new external magnet ring design allows the motor coupling hub disassembly without any further balancing.
Interchangeable hub permits the fitting of IEC or NEMA motors without changing the external magnet ring, besides it allows different motor sizes, thereby reducing inventory costs dramatically and increasing flexibility.
External magnet rings are interchangeable between GPM6 and GPM10 and between GPM15 and GPM30.
