AQUASTRONG 1.5 HP Shallow Well Pump
This shallow-well jet/centrifugal pump combines robust cast-iron construction with streamlined flow. It delivers up to 4250 GPH with a maximum head of 108 ft, suitable for medium-sized irrigation tasks. The unit features a reinforced impeller and diffuser for high efficiency and strong water delivery, plus dual voltage support (115/230 V) with factory setup at 230 V for easy installation. The 2″ NPT suction and 1-1/2″ discharge maximize portability for lawn and garden irrigation projects while maintaining reliable performance.
Red Lion RL-SPRK150 1.5 HP
Designed for reliability in well and lake water scenarios, this cast-iron pump with a glass-filled thermoplastic impeller provides solid durability. It supports dual voltage operation (115/230 V) with factory setup at 230 V and easy switching to 115 V to match your power source. Priming is straightforward with a one-time priming process, after which no repeat priming is typically needed. The combination of metal housing and reinforced impeller helps resist wear in challenging irrigation environments.
AQUASTRONG 2 HP Shallow Well Pump
This higher-capacity variant offers up to 5200 GPH with a max head of 108 ft, enabling robust irrigation for larger lawns. It employs a reinforced impeller and diffuser to maintain efficient water flow under demanding conditions. The unit is designed for 230 V operation with a strong square-flange motor, ensuring stable power delivery and long service life in sprinkler systems that require more water output.
Goulds GT15 IRRI-Gator
Goulds GT15 IRRI-Gator features a self-priming design that suits sprinkler systems requiring quick setup and minimal maintenance. It’s fully serviceable and uses an FDA-compliant impeller, ensuring dependable performance with a focus on longevity and ease of parts replacement. This pump is well-suited for users who value straightforward maintenance and long-term operability in irrigation applications.
AQUASTRONG 1.6 HP Portable Pump
This portable unit delivers up to 1320 GPH at 5 ft of head, supported by a 1.6 HP motor. It features stainless steel casing and corrosion-resistant construction, plus automatic shutoff for protection when water runs low. While not a self-priming model, its portability and durable build make it suitable for temporary irrigation setups, garden transfer tasks, and off-grid sprinkler configurations where mobility matters.
Flotec FP5172 Pump For Sprinklers
Flotec FP5172 provides self-priming, corrosion resistance, and high-capacity sprinkler capabilities. It supports up to 30 sprinkler heads and dual voltage operation (115/230 V). Built with rugged fiberglass-reinforced thermoplastic, it’s designed for demanding irrigation tasks and higher-temperature water up to 140 °F (60 °C). This model suits larger residential systems needing consistent head pressure across multiple zones.
Red Lion RL-SPRK150-BR 1.5 HP
This variant extends the ruggedness with a cast-iron housing and robust brass impeller, designed to handle abrasive water conditions such as ditch water or reservoir supply. It offers dual voltage (115/230 V) with factory settings for 230 V and an easy switch to 115 V. One-time priming simplifies initial setup and reduces ongoing maintenance for steady sprinkler operation.
Buying Guide
Key considerations help align a sprinkler pump with your landscape needs and power constraints:
- Flow rate and head: Match the pump’s GPH and maximum head to your sprinkler system’s zone requirements. Higher GPH supports larger areas, while sufficient head ensures spray pressure across all zones.
- Voltage and power needs: Dual-voltage models offer versatility for different electrical setups. Confirm available outlet voltage and circuit capacity to avoid overloads.
- Priming: Self-priming designs simplify initial setup and reduce prime-related issues. Consider one-time priming versus ongoing priming requirements for your layout.
- Material durability: Cast iron housings resist wear in harsh water conditions, while brass impellers withstand mineral content better than some plastics. Choose based on water quality and expected maintenance.
- Ease of maintenance: Fully serviceable pumps and widely available replacement parts extend lifetime and minimize downtime during repairs.
- Port connections: Ensure suction and discharge fittings (sizes like 2″ NPT suction and 1-1/2″ discharge) align with existing piping and hoses in your irrigation system.
- Noise and efficiency: Look for energy-efficient motors and well-insulated housings if the pump will operate near living spaces. Consider square-flange or other motor designs for reliability.
- Portability versus fixed installation: Portable models provide flexibility for seasonal tasks or temporary setups, while fixed pumps offer consistent performance for a perennial sprinkler system.
- Water source compatibility: Some pumps are optimized for well water, while others handle lake, ditch, or municipal supplies. Validate your water source to minimize wear and fouling.
