Moving the thick slurries found in quarries is a challenge for any submersible pump. Tsurumi Pump, the world’s largest manufacturer of submersibles has developed a new series for this application.

Introduced to Australia and the South Pacific by Australian Pump Industries, the new KTV is a cast iron, heavy duty slurry pump with an integrated agitator. The agitator stirs the solids laded liquid so that suction is smooth and efficient.

The pump also 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. This allows for installation in confined spaces.

That constant flow of liquid keeps the motor cool, extending life and enabling it to continue to operate even in shallow water. Tsurumi engineers claim the KTV can continuously operate in depths as shallow as 140mm, or a little over five inches. The semi-vortex pump design minimizes start-up failure from blocked impellers.

“There are two models in the series, powered by 2kW and 3kW, three-phase 415v motors. Both are suitable for DOL starting making them easy to install and operate in the field,” said Aussie Pumps’ Craig Bridgement.

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, is a standard Tsurumi feature. Ball bearings are double shielded and both the impeller and agitator are high chrome, cast iron for maximum wear resistance.

The cable is fitted with a unique anti-wicking gland that will block the ingress of water to the motor in the event the power cable is submerged or “wetted”. “Cable damage is a major cause of premature failure,” said Bridgement. “The anti-wicking gland has saved thousands of motors from burn out.”

A Circle Thermal Protector is fitted as standard equipment. The CTP 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 eight metre heavy duty chloroprene rubber cable is supplied as standard equipment.

These heavy duty pumps are inexpensive and come with a unique three year warranty. “The KTV Series has proved itself in batch plants and quarries in SE Asia and Japan. Now it’s ready for Australia’s slurry applications.” said Bridgement.
