The DVS model pump has a unique semi-vortex construction of EBARA's own design. This pump is as efficient as a conventional non-clog pump which uses the centrifugal force of eddy to pump liquids. As you can see, any foreign matter sucked into the pump must pass the impeller, which can result in trouble caused by clinging grass and clogged stones.
With the vortex pump, foreign matter is expelled by the force of eddy which is
formed in the wide space between the impeller and the suction cover. There is less likelihood of clogging.
