Non-clog
・Unique impeller design prevents overload under severe operating conditions.
・Semi-open non-clog impellers prevent pump clog by foreign matter. 4 pole induction motor runs with high torque to enhance foreign matter passing.
・Flow condition is less affected by water level fluctuation in the pit due to hydraulic design.
・Built-in motor protector (automatic cut-off for model below 7.5kW and thermal protector over 11kW) protects the motor from overload or open phase.
・Optional quick discharge connector facilitates easy installation and maintenance.
・Model DLA permits automatic operation.
Parallel alternate operation possible with model DLA and DLJ.
・Optional cutter mechanics is available for limited models.
Cocoon-shaped inlet design for below 80 mm discharge and radial groove design for 100 mm discharge is enhanced passing fibrous materials.
