Product catalog summary
Overview: The Tsurumi PNI-series submersible wastewater pumps are designed with a combination of resin and stainless steel, offering a compact, lightweight, and durable solution for wastewater management. These pumps are energy-efficient, reducing power consumption by approximately 20% compared to competitors.
Specifications: The pumps feature a discharge bore of 50 mm, a semi-vortex impeller made from glass-fiber reinforced resin, and dual inside mechanical seals with silicon carbide for enhanced durability. They are equipped with a dry-type submersible induction motor available in 0.4 kW and 0.75 kW outputs.
Design and Materials: The PNI-series utilizes special resins with advanced treatment for improved durability and corrosion resistance. Key materials include PPS-(MD+GF)50 for heat and chemical resistance, PPO-GF20 for waterproofing, and ABS-GF20 for impact resistance.
Features: The pumps include a removable handle, anti-wicking cable entry (except AUTO type), motor protectors, and an Oil Lifter for seal lubrication. The back pull-out design facilitates maintenance, and an air release valve prevents air lock.
Automatic Operation: The AUTO type includes a bell-shaped float switch for automatic operation, allowing for manual and auto modes. The float switch is adjustable, enabling operation in limited spaces and reducing malfunction risks in oily wastewater.
Applications: Suitable for installation in septic tanks, small-scale wastewater treatment facilities, and water features in fish ponds due to the use of food-grade liquid paraffin oil.
Performance: Performance curves indicate the pump's capacity and total head at different speeds (3000 min-1 and 3600 min-1) for both 50 Hz and 60 Hz models.
Conclusion: Tsurumi's PNI-series pumps integrate original technologies for enhanced durability, maintainability, and safety, making them a reliable choice for various wastewater applications.

Submersible Resin Made Wastewater Pumps Tsurumi’s PNI-series of submersible wastewater pumps are made of resin and stainless steel, which makes them compact, lightweight and easy to handle. The pumps feature an energy-saving design that reduces power consumption by approx. 20% in comparison with competitor pumps of equivalent output class. The combination of resin and stainless steel provides excellent durability and corrosion resistance regardless of the lightweight body. And, the resin material used for these pumps is selected for the relevant parts. Therefore, the PNI-series is more advantageous...

Special Resin The resin used for the PNI-series is not simple resin, but special resins produced by applying advanced treatment to elaborate compound material. Each pump component is made of resin that has been compounded at the optimum ratio for the role of the relevant parts. Therefore, the PNI-series is more advantageous in terms of durability and corrosion resistance than simple resin pumps. PPS-(MD+GF)50 - Excellent heat resistance and chemical resistance, and high mechanical strength PPO-GF20 - Water-proofing, and resistance to acids and alkalis ABS-GF20 - Excellent impact resistance, water-proofing,...

AUTO Type - Automatic Operation • Automatic and manual operation modes can be changed over with a single switch. • The bell-shaped float moves only up/down, so this pump is suitable for installation in limited/cramped places. • This model enables drainage at lower water levels than pumps with a float for general start/stop water level. • With the adjustable float switch, this pump can work at a water level suitable for field conditions. • The possibility of float malfunction is low, even in wastewater containing a certain amount of oil. Automatic Operation The process is repeated. Installation...
