Submersible pump Tsurumi PU Series

Tsurumi PU series submersible wastewater pumps are an excellent solution for projects involving wastewater and liquids containing impurities. With a corrosion-resistant design crafted from plastic and 304 stainless steel, these pumps operate efficiently and reliably even in harsh environments. A key feature is the spiral impeller mechanism, which ensures stable pumping performance even in the presence of solids. Additionally, the use of liquid paraffin lubrication broadens the device’s application range to include decorative installations such as water features, fish ponds, and aquaculture systems.

Construction of the Tsurumi PU Series Submersible Wastewater Pump

The Tsurumi PU series pump is constructed from stainless steel and corrosion-resistant plastics, making it lightweight and capable of withstanding acidic water. Its design features a spiral impeller with a wide flow passage, allowing it to efficiently handle wastewater containing chemically corrosive substances.

Below are the details of the internal components of the Tsurumi PU series pump:

Cable Head Each pump cable is equipped with waterproof connectors. This system includes conductors sealed with rubber or molded epoxy, which prevents water from infiltrating along the wiring.

Motor The motor is a dry-type squirrel-cage induction motor housed in a waterproof enclosure and equipped with E-class insulation, which allows it to withstand ambient temperatures of up to 40°C while operating efficiently and safely.

Motor Protection Device When the motor is overloaded or running dry, this device automatically cuts the circuit to prevent overheating and damage. Its auto-reset feature is especially important, as it allows the motor to safely restart once temperatures return to normal.

Removable Design The pump casing can be easily disassembled into the pump unit and the motor with impeller by removing the bolts between the top head and the pump housing with a screwdriver. This simple disassembly ensures that the equipment can be maintained easily and will continue to operate reliably over the long term.

Mechanical Seal The mechanical seal consists of two sealing surfaces embedded with silicon carbide (SiC) and is equipped with an oil chamber, which completely eliminates the risk of corrosion, wear, or clogging, thereby preventing potential seal failures.

Pump Impeller A spiral impeller is installed at the top of the pump casing. Combined with a large flow passage, this design effectively transports and processes coarse solids with particle sizes of up to 35 mm.

Oil Lifter The Oil Lifter serves as an efficient lubrication device for the mechanical seal. Utilizing the centrifugal force from the pump shaft, it continuously supplies lubrication even when the oil level drops below the designated threshold. This not only ensures effective lubrication and cooling but also maintains a stable seal and extends maintenance intervals.

Key Features of the Tsurumi PU Series Pump

• Stainless Steel Casing: Constructed from high-quality stainless steel, the pump casing is corrosion-resistant, enhancing durability and extending the pump’s lifespan.
