GA / GB Series pumps are equipped with vortex impeller. The benefit of a vortex impeller over a
channel impeller is the minimized risk of clogging. A vortex impeller is also a better choice and
pumped liquid has a high content of sand. These pumps have large free passage up to 3½” in
diameter suitable for lifting of sewage liquid, civil waste and industrial waste water containing
solids and viscos materials, heavy muds or fermented sludge.
