Tsurumi LB-800A

Automatic Tsurumi Submersible pump with top discharge provides maximum motor cooling efficiency allowing continuous duty operation at low water levels and extended dry-run capability. Tsurumi Automatic Dewatering Pump has sensitive electrodes that detect water and automatically begin operation even when foreign materials are present. An internal timer extends motor life by preventing the motor from engaging and disengaging frequently. Job site tested for more than 30,000 on/off cycles without failure or damage. Tsurumi Dewatering pumps have semi-open urethane impeller with a natural rubber wear plate and casing. Long 50FT power cord.

Disigned to fit an 8" pipe. Easy disassembly with one 12mm box / socket wrench.

  • Up to 60' shut off head.
  • 115 volt, available in 220 V single-phase for lower amperage draw and longer cable extensions. Motor is thermally protected.
  • Double Inside Mechanical Seal with SiC faces, 7oz oil bath provides the longest operation life.
  • Urethane rubber-coated impeller is more abrasion-resistant and lasts up to 3 times longer than a cast iron impeller
  • Oil Lifter provides lubrication of the seal faces and extends seal life by ten times.
  • Automatic level control with electronic electrodes that detect water to start pump even when lots of debris in the water. No float switch, no cycling in rough water. All protected in rubber case. Jobsite tested for more than 30,000 cycles.
  • Continuous LOW running water level 2", 6-3/4" to start the pump. Pump down timer set at 1 minute.
  • Multi-directional discharge connector.
  • 2" top discharge can be set vertical or at 90 degree
  • Large inlet strainer with 1/4" holes.
  • 2 Year warranty
