Suspended Solids
The SHO pumps are not drainage pumps, so can not be used for applications like waste water disposal or black waters. The SHO series can be used in washing systems or for clean water with small solid particles included. The recessed position of the impeller allows the pumping of liquids with small solid particles reducing the risk of clogging the pump. The dimensions of the solids are indicated in the table.
