Tsurumi 80PUA22.2 Stainless Steel Automatic Submersible Pump for Wastewater Handling with Vortex Impeller

Automating site drainage and managing high-volume wastewater requires a pump that combines high-capacity hydraulics with automatic level control. This automatic submersible vortex pump is configured for unattended operation, making it ideal for managing aggressive liquids in large-scale sumps. Its robust construction and vortex hydraulics ensure consistent performance in environments where manual monitoring is not feasible.

Driven by a 2.2 kW / 415v three-phase motor, the system delivers a maximum flow capacity of approximately 800 L/Min and achieves a peak head of approximately 18.5 m. The automatic control circuitry provides start and stop based on liquid level, while the Direct on Line starting method ensures immediate response to rising liquid levels. This power rating facilitates high-pressure discharge through an 80 mm bore for effective vertical transfer.

The hydraulic configuration utilizes a vortex impeller manufactured from glass-fiber reinforced PA+ABS, enabling the passage of large solids up to 46 mm. This recessed design minimizes mechanical contact between debris and the impeller, significantly reducing erosive wear during continuous operation. The vortex behavior ensures stable hydraulic efficiency and prevents obstruction when managing high concentrations of solids-bearing wastewater in automated cycles.

Mechanical integrity is supported by a 304 stainless steel and resin frame, with a double-face mechanical seal located in an oil chamber featuring an Oil Lifter. Protection is enhanced by a circle thermal protector built into the motor housing and an anti-wicking cable entry block. The unit utilizes non-toxic liquid paraffin as a lubricant, ensuring the pump is suitable for applications where liquid contamination must be avoided.

FEATURES

• Automatic operation provides unattended management of large industrial sumps.
• High-grade 304 stainless steel and resin construction offer exceptional corrosion resistance for wastewater applications.
• Vortex impeller made of glass-fiber reinforced PA+ABS enables a 46 mm solids passage without internal clogging.
