Tsurumi KTV compact slurry pumps

A compact, portable submersible pump with a powerful agitator for draining slurry and pumping sediment is now available from Australian Pump Industries. The product is made by submersible pump manufacturer Tsurumi, and is aimed at the concrete mixing and batch plant market.

The KTV slurry pumps are designed to pump sand-laden water and also aid in the reclamation of materials from unused concrete at batch plants. The pumps offer capacities of up to 420 L/min flow and heads as high as 22 m. The series includes both 50 and 80 mm discharges and is fitted with three-phase, 2-pole high-efficiency motors with thermal and amperage protection against dry running or overloading.

The product includes a double mechanical seal with both top and bottom silicon carbide seal faces running in an oil-filled chamber for extended life. The mechanical seal also features an ‘oil lifter’ developed to enhance seal performance. The design of the seal enables the lifter to oil the top seal faces, even if the lubricant level drops below manufacturer’s recommendations. The lubrication cools the seal faces, providing longer life and reducing wear.

The pump range features a high-capacity, semiopen-style impeller to minimise the risk of impeller block at start-up. The impeller is made from high-chrome cast iron for wear resistance, and the casing is synthetic rubber. The shaft seal is a double design, silicon carbide, while the pump shaft is 420-grade stainless steel.

Standard equipment includes heavy-duty 8 m cable to Tsurumi’s antiwicking block. The antiwicking block prevents the ingress of water into the motor even if the cable is damaged or worn.
