Tsurumi 8-PN Submersible Corrosion-Resistant Water Feature Pump | 1/2 HP 115V

Product Details

The Tsurumi 8-PN (part of the VANCS series) is a premium, corrosion-resistant submersible pump designed for high-performance water transfer in environments where standard cast iron pumps would fail. Constructed from a sophisticated combination of 304 Stainless Steel and fiberglass-reinforced resin, this 1/2 HP pump is exceptionally lightweight yet incredibly durable. It solves the problem of premature pump failure in corrosive environments, making it the top choice for saltwater applications, decorative waterfalls, and septic effluent systems.

Key Features:

• Corrosion-Resistant Materials: Built with 304 Stainless Steel and glass-filled resin, ensuring long-term survival in harsh environments and even saltwater.
• Vortex Impeller Technology: The semi-vortex resin impeller creates a whirlpool action that allows many solids to pass through without touching the impeller, significantly reducing wear and clogging.
• Eco-Friendly Lubrication: Uses food-grade liquid paraffin oil, making it safe for use in fish ponds, decorative fountains, and aquatic displays.
• Dual Inside Mechanical Seals: Silicon Carbide faces are housed in an oil chamber, providing a superior barrier against moisture and motor burnout.
• Patented Oil Lifter: Ensures the mechanical seals are continuously lubricated and cooled, even if the pump is installed horizontally or if oil levels are low.

Specifications:

• Motor Output: 0.5 HP (0.4 kW)
• Voltage: 115V / 1-Phase / 60Hz
• Discharge Size: 2" NPT
• Max Flow Rate: 79 Gallons Per Minute (GPM)
• Max Head: 39 Feet
• Max Solids Diameter: 0.4 inches (10mm)
• Cable Length: 20 Feet
• Weight: 15.7 lbs (Extremely portable)

Installation & Maintenance Tips:

• Saltwater Use: If used in saltwater or brine, we recommend rinsing the exterior of the pump with fresh water whenever it is removed for maintenance to prevent salt crusting.
• Air Lock Prevention: Ensure the pump is submerged properly before starting. If the pump runs but doesn't move water, it may have an air lock; tilt the pump slightly while submerged to release trapped air.
• Strainer Cleaning: Periodically check the suction intake for leaves or plastic debris, especially when used in outdoor ponds or water features.

Common Uses/Applications:

• Decorative Waterfalls & Ponds: The oil-free cooling design makes it safe for Koi and other sensitive aquatic life.
• Saltwater Aquariums & Facilities: Highly resistant to the corrosive effects of seawater and brine.
• Septic Effluent: Reliable enough to handle the harsh chemicals and small solids found in residential and commercial septic systems.
• Commercial Fountains: Provides high-flow performance with a discreet, low-maintenance design.

Common Questions:

Q: Is this pump safe for fish?

A: Yes! The 8-PN uses food-grade paraffin oil for its lubrication, so there is no risk of toxic contamination if a seal were ever to fail.

Q: Can this pump handle large solids like a sewage pump?

A: No. It is an effluent pump designed for clear water or water with small suspended solids (up to 0.4"). It is not designed for raw sewage or large debris.

Q: Can I install this pump horizontally?

A: Yes, thanks to Tsurumi's patented Oil Lifter, the mechanical seals will remain lubricated even in a horizontal orientation.

Whether you are powering a large-scale waterfall or managing corrosive effluent, the Tsurumi 8-PN provides the perfect balance of lightweight portability and industrial-strength durability.
