GREENPUMPS - Model GPCTA -GPTA Sealless Alloy and Plastic Centrifugal Pumps

The GPTA series includes the Sealless Alloy Centrifugal Pump and the Sealless Plastic Centrifugal Pump, each designed for specialized applications requiring reliable performance in low flow, high head conditions. These pumps feature a double stage construction. The first stage utilizes a Francis vane centrifugal impeller, which efficiently maintains a low NPSH requirement while facilitating the flooding of the second stage's regenerative turbine impeller. This design is particularly suitable for handling high vapor pressure liquids. The pumps are further optimized with an external high-speed gearbox to significantly increase differential pressure, enabling them to meet precise operating requirements. The technical design makes these pumps suitable for industrial applications that demand efficiency and adaptability under varying pressure conditions.
