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 GPA BENEFITS
GREENPUMPS GPA Sealless Sliding Vanes pumps are designed and fabricated for constant low flow and high head self regulating applications. All GREENPUMPS, due to their 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.
GREENPUMPS GPA SPECIFICATIONS
GREENPUMPS GPA Sliding Vane pumps can maintain design head and flow for an extended running period because of self compensating carbon vanes.
GPA are suitable for thin non lubricating mediums, they eliminate pressure drop without rapid wear of carbon parts.
