Tsurumi KTD22.2 Cast Iron Agitator Submersible Slurry Pump for Sand & Mud Handling with Semi-open Impeller

Construction contractors and mining operators rely on this submersible slurry pump where abrasive media such as sand, mud, and bentonite slurry must be transferred continuously. It is specifically configured for foundation works and industrial sites where sediments would settle and obstruct standard drainage systems. The unit delivers dependable service duty under heavy abrasive loads, ensuring consistent site maintenance without the frequent downtime associated with conventional dewatering equipment.

Powered by a 2.2 kW / 415v three-phase induction motor, the pump is capable of up to approximately 21.5 m of head and up to approximately 550 L/Min flow through a 50 mm discharge bore. These performance figures are maintained by a 2-pole motor operating at a synchronous speed of 3000 min-1, delivering the necessary mechanical torque to displace thick fluids with a specific gravity higher than standard wastewater. The unit maintains stable operating behavior while handling fluids with up to 10% dry matter content across a pH range of 5 to 9.

Wear resistance comes from a high-chromium cast iron semi-open impeller paired with a shaft-mounted agitator made of ductile cast iron. The agitator rotates to create a downward current that actively suspends settled solids into the fluid, facilitating smooth suction and preventing intake blockages. This configuration allows for the continuous transport of solids up to 10 mm while minimizing internal turbulence and hydraulic losses during the passage of abrasive particles.

A heavy-duty cast iron body and top discharge, side flow design ensure efficient motor cooling even when operated with the motor housing partially exposed to air. Mechanical integrity is supported by dual inside mechanical seals with silicon carbide faces isolated in an oil chamber featuring Tsurumi's original Oil Lifter for enhanced lubrication. A built-in circle thermal protector directly cuts the circuit during overcurrent or excessive heat conditions, while the anti-wicking cable entry prevents moisture ingress through capillary action.

FEATURES

• Shaft-mounted high-chromium cast iron agitator prevents sediment accumulation by stirring solids into suspension at the intake passage.
• Top discharge, side flow cooling path facilitates continuous operation in low-water levels by dissipating motor heat directly to the pumped media.
• Dual inside mechanical seals with silicon carbide faces provide superior resistance to abrasion and corrosion in sandy slurry duty.
• Patented Oil Lifter maintains seal face lubrication and cooling even if the lubricant level falls below the rated volume.
• Anti-wicking cable entry prevents water incursion into the motor housing due to capillary action or damaged cable sheaths.
• Built-in circle thermal protector proactively guards the motor against thermal stress and electrical overcurrent conditions.
• High-chromium iron semi-open impeller resists erosive wear to maintain original hydraulic performance over extended service cycles.
• Slim cylindrical design reduces the overall pump diameter to allow for installation in confined pits and narrow excavations.
