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 GPTA BENEFITS

GREENPUMPS GPTA Sealless Alloy Centrifugal Turbine pumps are designed and fabricated for low flow and high head 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 glands eliminates dangerous emissions in order to protect the environment and workers.

 

GREENPUMPS GPTA SPECIFICATIONS

GREENPUMPS GPTA Alloy Centrifugal Turbine pumps can maintain design head and flow for an extended running period.


The multi-vanes self-balancing impeller’s construction eliminates the thrust loads and can be started with completely open discharge valve. GPTA are
suitable for thin non lubricating mediums with a very low NPSH available value.

  • Discharge head up to 100m;
  • Temperature range – 100
    °C up to 315
    °;
  • Specific gravities up to 2 kg/dm3;
  • System pressure rating from 25 bar (350 PSI)
  • Special design up to 450 bar (6500 PSI)
  • Reversible rotation
  • Can be used like a mixer, for liquids having different characteristics

 

GREENPUMPS GPTA FEATURES

  • Fully encapsulated external magnet;
  • Bronze Rub ring standard on coupling housing;
  • Low flow high head capability minimizes by-pass requirement;
  • Heavy duty machined pressure parts;
  • Reduction of maintenance costs by replaceable impeller;
  • Low maintenance costs;
  • High MTBF (mean time between failure);
  • High torque Cobalt Samarium magnets;
  • Easy removable pedestal for all frames;
  • Pumps are in accordance to ATEX regulation category;
