Submersible recirculation pump
DN 300 - 800, 1450 l/s | SRP series GRUNDFOS

The Grundfos range of recirculation pumps is the final result of decades of engineering experience. Created to handle large flows against low head, the SRP models are equally suitable for wastewater treatment plants and flood control.

SRP units come in three main variants - DN 300, 500, or 800 mm, respectively, fitted with motors from 0.8 to 24 kW. The units share many features with the AMG and AFG geardriven mixers and flowmakers, making them instantly familiar to service staff and facilitating easy maintenance.

Recent evolutions include a triple sealing system for maximum protection of the mechanical shaft seal as well as a very installation-friendly bracket.
