Tsurumi 2-PU Submersible Corrosion-Resistant Solids Pump | 1/5 HP 115V

Product Details

The Tsurumi 2-PU is a highly specialized 1/5 HP submersible pump from the VANCS series, engineered specifically for sewage and wastewater applications. Unlike the effluent-focused PN series, the PU series features a wide-clearance vortex impeller design that allows it to pass significant solids without clogging. Built with a combination of 304 Stainless Steel and fiberglass-reinforced resin, it solves the problem of corrosion in harsh wastewater environments while remaining lightweight and portable. It is the ideal solution for residential sewage basins, light industrial waste, and high-end water features where debris handling is a priority.

Key Features:

• Superior Solids Handling: The semi-vortex impeller design creates a whirlpool effect that allows solids up to 1.38 inches to pass through the pump housing without clogging the impeller.
• Corrosion-Resistant Construction: Made with a 304 Stainless Steel motor frame and glass-filled resin casing, ensuring a long service life even when exposed to acidic wastewater or damp environments.
• Fish and Plant Safe: Lubricated with high-grade, food-grade liquid paraffin oil, making it completely non-toxic for use in decorative ponds containing sensitive aquatic life.
• Dual Inside Mechanical Seals: Silicon Carbide faces are housed in an isolated oil chamber, providing industrial-strength protection against motor water-ingress.
• Patented Oil Lifter: Ensures the mechanical seals are continuously lubricated and cooled, even if the pump is installed horizontally or if oil levels drop.

Specifications:

• Motor Output: 1/5 HP (0.15 kW)
• Voltage: 115V / 1-Phase / 60Hz
• Discharge Size: 2" NPT
• Max Flow Rate: 35 Gallons Per Minute (GPM)
• Max Head: 18 Feet
• Max Solids Diameter: 1.38 inches (35mm)
• Weight: 13.5 lbs (Lightweight and durable)
• Cable Length: 20 Feet

Installation & Maintenance Tips:

• Positioning: For optimal performance in sewage basins, ensure the pump is placed on a stable base to prevent it from tipping. The vortex design is very forgiving, but keeping the intake clear of large stones is recommended.
• Air Venting: The pump features a built-in air relief valve to prevent air-lock. If the pump is installed in a new basin, ensure it is fully submerged to allow the casing to prime correctly.
• Routine Cleaning: While designed for solids, it is a good practice to periodically check the suction area for stringy materials (like rags or long weeds) that can wrap around the impeller shaft.

Common Uses/Applications:

• Residential Sewage & Septic: Reliable removal of wastewater from basements or septic tanks to higher elevations.
• Large Water Features: Powers waterfalls and streams where leaves and small twigs are likely to enter the system.
• Industrial Wastewater: Handles drainage from food processing or light manufacturing facilities where corrosion resistance is required.
• Decorative Ponds: Safe for Koi and goldfish while providing the flow necessary for large-scale filtration.

Common Questions:

Q: What is the main difference between the PU and PN series?

A: The PU series (this model) is a sewage pump with a vortex impeller designed to handle larger solids (up to 1.38"). The PN series is an effluent pump designed for cleaner water or very small solids (up to 0.4").

Q: Can this pump handle raw sewage?

A: Yes, the 2-PU is rated for raw sewage and wastewater containing solids up to its rated 1.38-inch capacity.

Q: Is this pump intended for automatic or manual use?

A: The standard 2-PU is a manual pump. To operate it automatically in a sump or sewage pit, you should use a piggyback float switch or look for the "A" (automatic) version.

With its impressive solids-handling capacity and lightweight, corrosion-resistant design, the Tsurumi 2-PU is the perfect solution for demanding wastewater and large-scale aquatic applications.
