JKA is headquarters for clog-free wastewater pumps: JKA is your headquarters for “clog-free” wastewater pumps. Regardless of whether your requirement is for a submersible or above ground pump, JKA has a solution when it comes to replacing pumps with clogging issues. The new SHV series from Barnes outperforms the competition when it comes to passing difficult solids in wastewater transfer. Weinman horizontal vortex pumps excel at passing difficult solids with their recessed impeller design. BJM submersible shredder pumps “chew up and spit out” any difficult solids they encounter. These are just a few of the solutions JKA can offer for difficult wastewater applications. Ask an associate for details.
