THESE GENERAL PURPOSE THREE-PHASE 200 TO 480V SEWAGE EJECTOR PUMPS USE A HIGHER VOLTAGE THAT ALLOWS FOR LARGER MOTORS THAT REQUIRE LESS CURRENT THAN LOWER-VOLTAGE MOTORS THEY ALSO USE THREE-PHASE POWER THATS MORE EFFICIENT THAN ONE-PHASE POWER PUMPS REMOVE SEWAGE CONTAINING SOLIDS FROM DRAINS WHERE A GRAVITY SYSTEM WONT WORK SUCH AS IN SEPTIC SYSTEMS THAT ARE BELOW THE MAIN SEWER LINESEWAGE EJECTOR PUMPS REMOVE SEWAGE CONTAINING SOLIDS FROM DRAINS WHERE A GRAVITY SYSTEM WONT WORK SUCH AS IN SEPT
