Tsurumi Pump

Rotary

Discharge Bore (mm): 20 – 150

The RS-series rotary air blowers are equipped with a 3-lobe rotor.

These blowers have helical structure at the intake and the outlet. This makes the air virtually pass through a gradually closing suction port or gradually opening discharge port. The result is remarkably reduced pulsation noise.

Discharge Bore (mm): 50 ･ 80

Motor Output (kW): 0.75 – 11

The SF-series is a submersible high-head drainage pump designed for handling wastewater and liquid carrying ignorable size of solids. A semi-open, multi-vane impeller driven by a 2-pole motor enables the pump to work for pumping from a deep underground or to a distant place.

Air-inlet Bore (mm): 65 – 250
Motor Output (kW): 1.5 – 30

The TAR-series is a submersible air mixer that combines aeration and mixing to promote wastewater treatment at public and industrial treatment plants. The powerful current discharged from the high-performance axial-flow impeller shears the air supplied by the blower into tiny bubbles, forming a furious flow of mixed air and water that efficiently delivers oxygen throughout the wastewater.

Air-inlet Bore (mm): 32 – 150

Motor Output (kW): 0.75 – 40

The TRN-series is a submersible self-aspirating aerator designed for aeration and mixing of wastewater. The liquid flow generated by Tsurumi’s special semi-open impeller causes negative pressure to form on the backside of the impeller vanes and draw in air from above the water’s surface. The aspirated air, mixed with water viciously by mechanical forces inside the impeller and guide vane, transforms into tiny bubbles.
