Centrifugal Pump, 15 HP, 260 ft. Max. Head
Brand: Goulds. Features include a max head of 260 feet, 2″ NPT inlet and 1-1/2″ NPT outlet, cast iron housing, and a 15 HP motor with three-phase operation. This high-head model is designed for demanding irrigation, water transfer, and industrial applications where head is the limiting factor. Best for operations needing significant height push and robust materials. Limitations: heavy and requires appropriate electrical and mechanical room setup.
- Best for high-head irrigation and transfer tasks
- Open dripproof motor enclosure for 3-phase operation
- Sturdy cast iron construction with durable wetted materials
Caution: Ensure electrical supply and mounting accommodate the weight and vibration of a high-head, 15 HP pump.
Centrifugal Pump, 15 HP, 200 ft. Max. Head
Brand: Goulds. Notable specifications include a 200 ft max head, 3″ inlet, 2-1/2″ outlet, 215JM frame, 3500 RPM motor, and 208-230/460 VAC variants. Wetted materials include 303 stainless steel, carbon, cast iron, and bronze. Best for mid-to-high head systems requiring solid corrosion resistance and reliable high-flow performance. Caution: data shows 3-phase operation; confirm electrical compatibility before purchase.
- Best for versatile high-head setups
- Heavy-duty wetted materials for longevity
- Wide voltage options support flexible installations
Caution: This model is best where a three-phase supply is available; single-phase may require a VFD or alternative model.
Centrifugal Pump, 15 HP, 160 ft. Max. Head
Brand: Goulds. Features a max head of 160 feet, 3″ inlet and 3″ flange outlet, and a 15 HP motor with 208-240/460 VAC operation. Wetted materials include 303 stainless steel and cast iron. Best for compact installations where space is a constraint but high head is still needed. This model offers a balance of performance and footprint. Limitation: flange connections may require adapters in some installations.
- Choose this if space is limited but head remains high
- Robust casting and stainless components for durability
- Flange connections simplify secure piping
Caution: Verify flange compatibility with existing piping to avoid adapters or leaks.
TNEHOD 15 HP Vertical Centrifugal Pump
Brand: TNEHOD. This is a vertical, space-saving centrifugal pump with a 15 HP motor and multi-voltage capability. The vertical design reduces footprint in mechanical rooms or compact installations. Best for facilities with tight floor space or where vertical layout is preferred. Limitation: vertical pumps may require careful alignment with discharge piping and priming considerations.
- Best for space-constrained installations
- Durable build designed for heavy-duty, continuous operation
- Multi-voltage compatibility supports flexible power sources
GOULDS GT20 IRRI-Gator Self-Priming 2 HP
Brand: Goulds. Note: Included here for context as a comparison to 15 HP models. Features a self-priming design, 2 HP motor, and 1.5″ NPT connections. Best for small-scale irrigation or transfer tasks where a 15 HP unit would be oversized. Caution: It is not a 15 HP pump and should not be used where high head is required.
- Better for smaller projects or training scenarios
- Self-priming capability simplifies setup
Buying Guide: Key Purchase Considerations
What head and flow do you need? Compare max head and gallons per minute (GPM) at head ranges to match your system requirements. Higher head means more vertical lift capability, but ensure you have enough flow to satisfy your process.
What material and enclosure suit your fluids? In wetted parts and housings, cast iron and 303 stainless steel offer durability and corrosion resistance for typical irrigation and water transfer tasks. For aggressive fluids, verify compatibility with the wetted materials listed in the product specs.
What power supply is available? Many 15 HP Goulds units run on 208-230/460 VAC three-phase power. If you have a single-phase supply, consider a model with a built-in soft-start or a VFD/soft-start solution, and check enclosure type (ODP vs. TEFC) for protection against dust and moisture.
What installation space is required? Vertical designs save floor space, but require careful alignment, mounting, and plumbing. Horizontal models may be easier to service but occupy more area.
What maintenance and reliability are expected? Look for robust bearings, corrosion-resistant wetted parts, and long-term supply of spare parts. For industrial settings, ensure the motor and seal materials can withstand continuous operation and duty cycles.
Configuration tips: Match inlet/outlet sizes to your existing piping or plan adapters as needed. Check whether flange connections are standard or require gaskets and bolt patterns similar to your system. Consider adding a redundant backup or an emergency shutoff if the pump plays a critical role in facility operations.
Frequently Asked Questions
- What does 15 HP mean for a centrifugal pump?
Horsepower (HP) indicates the motor’s power output. A 15 HP pump can handle higher head and flow requirements suitable for larger irrigation, transfer, or industrial tasks.
- Do these pumps operate on single-phase power?
Most 15 HP centrifugal pumps in this set are three-phase. If single-phase power is needed, look for models with built-in soft-start or plan for an appropriate drive solution.
- What head should I expect with a 15 HP model?
Head ranges from about 160 ft to 260 ft in the listed Goulds models, depending on the exact model. Choose based on your system’s required lift.
- What maintenance is required for vertical 15 HP pumps?
Vertical designs often require careful alignment, periodic seal checks, and inspection of the motor and bearings for continuous operation in mechanical rooms.
- Is material compatibility important for irrigation pumps?
Yes. Wetted materials (stainless steel, bronze, and cast iron variants) determine resistance to corrosion and chemical exposure in irrigation and transfer tasks.
- How do I choose between 160 ft and 260 ft head pumps?
Consider your total dynamic head (TDH). If your system requires tall lift or long piping runs, prioritize higher head. For shorter runs, a lower head model may be more efficient.
