Tsurumi TM Series submersible pumps

A range of submersible pumps designed for corrosive liquids, including seawater, has been released. The saltwater subs are intended for a wide range of duties, from aquaculture to chemical spill containment.

Called the TM Series, the pumps are particularly suitable for applications where corrosion is an issue. The stator housing is titanium while the pump casing, stand and motor cap components are all manufactured from FRP resin moulded material. The material is completely compatible with hypersalinity liquids.

The pumps are compact in design and are available in either 50- or 60-cycle, single- or three-phase motor drives. They range from pumps capable of 240 L/min flow right up to 350 L/min. Heads range from 9 to 15 m. The entire range can be equipped with floats for automatic operation.

Duplexing systems - two pumps located side by side operating on an automatic alternating model - are also available. With the auto-duplexing system, the pumps will operate automatically without extensive control panels. The system is suitable for installations where one pump is normally enough for the capacity, but occasionally drainage or pump-out of a bilge may require more flow.

The series will be suitable for any saltwater application from drainage of fishponds, aquaculture and even decorative saltwater waterfalls.
