Advanced Technological Features of Tsurumi PN Series Submersible Wastewater Pumps
The Tsurumi PN series is equipped with advanced technology to enhance performance and ensure long-term durability. Key features include:
Special Impeller Design Designed with a unique angle and shape, the impeller increases flow rate and reduces energy consumption while effectively preventing large solids from clogging the pump.
High-Efficiency Motor The motor is decoupled from the impeller, reducing friction and noise, thereby extending its lifespan and operational efficiency. It is equipped with a liquid cooling system to ensure stable performance in harsh environments.
Anti-Clogging Mechanism The special design of the impeller and the large filter screen effectively prevent large objects from entering, ensuring smooth pump operation without clogging.
High-Quality Materials Constructed from premium materials such as cast iron, stainless steel, and technical plastics, the pump guarantees excellent durability and corrosion resistance in demanding conditions.
With these advanced features, the Tsurumi PN series pump meets the requirements for pumping wastewater and liquids with significant suspended solids, thereby enhancing operational efficiency and reducing maintenance costs.
Construction of the Tsurumi PN Series Submersible Wastewater Pump
The main components of the pump are manufactured from high-quality, corrosion-resistant materials, allowing continuous operation even when submerged. A meticulous design process and stringent manufacturing standards make the Tsurumi PN series a reliable choice for applications demanding high durability and dependability.
Cable Head Each cable is equipped with waterproof connectors. This system involves conductors sealed with rubber or molded epoxy, which prevents water from penetrating along the wiring, ensuring minimal leakage and enhanced safety.
Motor The motor of the Tsurumi PN pump is a dry-type squirrel-cage induction motor housed in a waterproof enclosure and compatible with E-class insulation. This design enables the motor to withstand ambient temperatures of up to 40°C while operating efficiently and safely.
Motor Protection Device If the motor is overloaded or running dry, this device automatically disconnects the circuit to prevent damage from overheating. Once temperatures return to normal, it resets automatically, allowing the motor to restart safely.
Removable Design The pump casing can be easily separated into the pump assembly and the motor with impeller by removing the bolts between the top head and the pump housing. This facilitates simple maintenance and ensures reliable long-term operation.
Mechanical Seal The mechanical seal features two sealing surfaces containing silicon carbide (SiC) and is equipped with an oil chamber to completely eliminate the risk of corrosion, wear, or clogging, thus preventing potential seal failures.
Pump Impeller A spiral impeller is installed at the top of the pump casing. Combined with a large flow passage within the casing, this design enables the pump to efficiently handle coarse solids up to 35 mm in diameter.
Oil Lifter The Oil Lifter is designed to provide effective lubrication for the mechanical seals. Utilizing the centrifugal force from the impeller, it supplies robust lubrication even when oil levels drop below the specified threshold, ensuring effective lubrication, cooling, and stable sealing while extending maintenance intervals.
