Tsurumi 12-PN Submersible Corrosion-Resistant Solids Pump | 1 HP 115V

Product Details

The Tsurumi 12-PN is the powerhouse of the VANCS series, offering high-volume water transfer in a lightweight, corrosion-resistant package. Delivering a robust 1 HP performance with a large 3-inch discharge, this pump is designed for applications where high flow rates and longevity are critical. Constructed from 304 Stainless Steel and fiberglass-reinforced resin, it solves the problem of moving large volumes of water in corrosive environments—such as saltwater or acidic effluent—without the weight or rust issues of traditional cast iron pumps.

Key Features:

• High-Flow 3" Discharge: Engineered to move massive amounts of water (up to 137 GPM), making it ideal for large-scale water features and professional drainage.
• Industrial Corrosion Resistance: The combination of resin and 304 stainless steel ensures the pump remains impervious to rust and chemical degradation in harsh wastewater or marine settings.
• Vortex Impeller Technology: The semi-vortex resin impeller creates a powerful whirlpool that allows solids up to 0.78 inches to pass through with minimal contact, reducing internal wear.
• Eco-Friendly & Safe: Lubricated with non-toxic, food-grade liquid paraffin oil, ensuring it is 100% safe for use in aquaculture, fish farms, and decorative koi ponds.
• Dual Inside Mechanical Seals: Silicon Carbide faces are isolated in an oil chamber, providing the best available protection against motor failure due to moisture.

Specifications:

• Motor Output: 1.0 HP (0.75 kW)
• Voltage: 115V / 1-Phase / 60Hz
• Discharge Size: 3" NPT
• Max Flow Rate: 137 Gallons Per Minute (GPM)
• Max Head: 44 Feet
• Max Solids Diameter: 0.78 inches (20mm)
• Weight: 18.1 lbs (Exceptionally lightweight for 1 HP)
• Cable Length: 20 Feet

Installation & Maintenance Tips:

• Pipe Sizing: To achieve the full 137 GPM flow rate, ensure you are using a full 3-inch diameter pipe or reinforced hose. Reducing the discharge size will increase backpressure and lower performance.
• Stable Footing: While the pump is lightweight, the high torque of the 1 HP motor can cause "kick" on startup. Ensure the pump is secured or placed on a flat, stable surface within the basin or pond.
• Check Valve: In high-head applications, install a 3-inch check valve to prevent the weight of the water in the vertical pipe from slamming back into the pump when it shuts off.

Common Uses/Applications:

• Commercial Waterfalls: Provides the high-volume "sheet" flow required for large residential or commercial rock waterfalls.
• Aquaculture & Hatcheries: Ideal for circulating and oxygenating large volumes of water in sensitive fish-rearing environments.
• Municipal Effluent: Reliable for moving treated wastewater in systems where chemical resistance is required.
• Saltwater Circulation: Perfect for large marine exhibits or saltwater intake systems where traditional metals would corrode.

Common Questions:

Q: Can I use this for raw sewage?

A: The 12-PN is an effluent pump designed for clear water or water with small suspended solids (up to 0.78"). For raw sewage containing larger solids, the PU series is recommended.

Q: Is this pump available in 230V?

A: Yes, this model (80PN2.75) is available in both 115V and 230V single-phase configurations to suit your specific electrical setup.

Q: Why is it so much lighter than other 1 HP pumps?

A: Tsurumi utilizes high-tech, fiberglass-reinforced resins for the casing and base, which provides the strength of metal without the heavy weight or susceptibility to rust.

The Tsurumi 12-PN is the ultimate solution for large-scale water movement, combining industrial-grade flow rates with a lightweight, corrosion-proof design that is safe for the most sensitive aquatic environments.
