model DL
Submersible pumps for sewage and waste water
Features and Benefits
- ・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.
