Tsurumi 3-PN Submersible Corrosion-Resistant Water Feature Pump | 1/5 HP 115V

Product Details

The Tsurumi 3-PN is the most compact offering in the professional VANCS series, providing a high-quality 1/5 HP solution for smaller-scale water movement. Designed for durability in environments that would corrode standard pumps, it is constructed from a robust blend of 304 Stainless Steel and fiberglass-reinforced resin. It solves the problem of finding a small-scale pump that doesn't sacrifice industrial features, making it the perfect choice for high-end residential ponds, small waterfalls, and light effluent applications where space and energy efficiency are priorities.

Key Features:

• Premium Corrosion Resistance: The combination of resin and 304 stainless steel ensures the pump remains rust-free and functional in damp or acidic effluent environments.
• Small Footprint, Big Performance: Despite its 1/5 HP motor, it delivers impressive flow rates for its size, fitting easily into tight sumps or hidden pond skimmers.
• Semi-Vortex Resin Impeller: Minimizes clogging by creating a whirlpool that allows solids to pass through without constant contact with the impeller vanes.
• Aquatic Life Safe: Lubricated with non-toxic, food-grade liquid paraffin oil, making it completely safe for Koi, goldfish, and aquatic plants.
• Dual Inside Mechanical Seals: Silicon Carbide faces are isolated in an oil chamber, protecting the motor from water ingress for a longer service life than standard utility pumps.

Specifications:

• Motor Output: 1/5 HP (0.15 kW)
• Voltage: 115V / 1-Phase / 60Hz
• Discharge Size: 1-1/4" NPT
• Max Flow Rate: 22 Gallons Per Minute (GPM)
• Max Head: 18 Feet
• Max Solids Diameter: 0.4 inches (10mm)
• Weight: 12.3 lbs (Lightweight and portable)
• Cable Length: 20 Feet

Installation & Maintenance Tips:

• Anti-Clogging: While the pump handles small solids (up to 0.4"), ensure the intake is kept clear of heavy stringy algae or large leaves to maintain the cooling flow around the motor.
• Priming: Ensure the pump is fully submerged before operation. If the pump is air-locked, briefly tilting the unit while submerged will release the trapped air bubble from the casing.
• Vertical/Horizontal Use: Thanks to the patented Oil Lifter, this pump can be operated in various orientations, providing flexibility in shallow pond or tank setups.

Common Uses/Applications:

• Small Ponds & Statuary: Powers small-to-medium decorative water features and statuary with minimal noise.
• Aquaculture: Used for water circulation and aeration in small tanks where non-toxic components are required.
• Basement Sumps: An excellent, corrosion-resistant alternative for small residential sump pits that collect clean or slightly sandy drainage.
• Aquarium Maintenance: Lightweight and portable enough for professional aquarium cleaning and water transfer.

Common Questions:

Q: Does this pump have a built-in float switch?

A: The standard 3-PN is a manual pump. If you require automatic operation, you can pair it with an external piggyback float switch or look for the "A" (automatic) version.

Q: Is it safe for use in continuous run waterfalls?

A: Yes, the 3-PN is rated for continuous duty as long as it remains submerged to properly dissipate heat from the motor.

Q: Can I use a garden hose with this pump?

A: The discharge is 1-1/4" NPT. You will need a reducer adapter (1-1/4" to 3/4" GHT) to use a standard garden hose, though this will significantly reduce the pump's flow rate.

The Tsurumi 3-PN is the ideal solution for users who need a small, energy-efficient pump that offers the same industrial-grade corrosion protection as Tsurumi's largest models.
