SUBMERSIBLE SEMI-VORTEX SEWAGE PUMPS
The DVS model pump has a unique semi-vortex construction of EBARA’s own design. This pump is as effi cient as a conventional non-clog pump which uses the centrifu-gal force of eddy “A” (see below) 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 “B” which is formed in the wide space between the impeller and the suction cover (“C”). There is less likelihood of clogging.
APPLICATIONS• Ideal for waste water application containing soft or fi brous solids• Industrial waste water drainage• Septic effl uent • Miscellaneous drainage
FEATURES• No clogging with semi-vortex construction• Semi-vortex impeller offers non-clog operation and allows pumping of foreign particle• Built-in motor protection• Double mechanical seal • DVSA model permits automatic operation• Parallel alternate operation possible with DVSA and DVSJ models
