Regenerative turbine pumps, 2/3 stages

GPCTA pump series are a variation of GPTA pumps.

This double stage construction pump is purposely designed for low NPSHa, low flow and high head applications. Firsts stage equipped with Francis vane centrifugal impeller in order to keep low the NPSH required and to flood the second and/or third stage that installs one/two regenerative turbine impellers.

Design curves of GPCTA pumps are similar to GPTA100 and GPTA200, while working specifications are like GPTA series.

Three stages with two booster impellers available on request.
