Tsurumi Pump KTV slurry pump

Moving thick slurries when dewatering on site is a challenge for submersible pumps, so Tsurumi Pump has developed a series for this application. The KTV is a cast iron, heavy-duty slurry pump with an integrated agitator, which stirs the solids-laded liquid so that suction is smooth and efficient.

The pump offers a side flow, top discharge design that enables the liquid to go from the pump chamber directly through a channel in the body housing through to the discharge port, allowing for installation in confined spaces. The constant flow of liquid keeps the motor cool, extending life and enabling it to operate even in shallow water.

There are two models in the series, powered by 2 and 3 kW, three-phase 415 V motors.  Both are suitable for DOL starting, making them easy to install and operate in the field. Tsurumi claims the product can continuously operate in depths as shallow as 140 mm. The semi-vortex pump design minimises start-up failure from blocked impellers.

The main impeller is a semi-open-style design that passes slurries with ease. Double silicon carbide mechanical seals, where both seal surfaces are oil-immersed away from the pumped liquid, are also a feature. Ball bearings are double-shielded and both the impeller and agitator are high chrome, cast iron for maximum wear resistance.

A Circle Thermal Protector protects from both excess heat and amp draw, shutting down the system before serious damage can occur. The shaft is 420-grade stainless steel. An 8 m heavy-duty chloroprene rubber cable is supplied and fitted with an antiwicking gland that will block the ingress of water to the motor in the event the power cable is submerged or ‘wetted’.
