Tsurumi B Series
Our B Series non-clog pumps are used primarily in municipal water supply stations and sewage treatment plants for pumping water, sewage, and digested sludge. In industry, these pumps are efficient for controlling cooling water, process and wastewater, and abrasive materials.
The guide rail fitting system connects the pump to and from the piping easily just by lowering and hoisting the pump, allowing easy maintenance and inspection without the need to enter the sump. Pump models used in combination with the guide rail fitting system can be identified by the prefix TOS or TO and TS.
TOS and TO
The TOS/TO is the standard guide rail fitting system made of cast-iron and is compatible with cast-iron pumps.
Special Features:
- Semi-open, single vane impellers (1 hp – 5 hp models)
- Enclosed multi-vane impellers (7.5 hp – 30 hp models)
- Field adjustable/replaceable wear plates
- Highly efficient air filled motors for continuous duty operation
- Available with class E, B, F insulation to minimize operation costs. Double inside mechanical seals with Sic-Sic faces operate in a separate oil-filled chamber.
- Anti-wicking block prevents water incursion to the stator if cable is accidentally damaged
- Double-shielded, permanently lubricated high-temp C3 ball bearings rated for B-10 life of 60,000 hours
