AQUASTRONG 1.5 HP Shallow Well Jet/Centrifugal Pump
The AQUASTRONG 1.5 HP model combines jet and centrifugal pumping for shallow wells and garden irrigation. It features a 2″ NPT suction and 1-1/2″ NPT discharge, delivering a maximum flow of about 4250 GPH (roughly 70+ GPM) and a maximum head up to 108 ft. The pump uses a reinforced impeller and diffuser to improve efficiency and water delivery, making it suitable for larger yards or setups with multiple zones. Dual voltage support (115/230 V) and a round flange motor provide flexible power options and efficient operation, with factory 230 V configuration simplifying setup.
Key considerations include the dual-voltage design, which helps if you’re upgrading power or relocating the system. Its cast-iron body offers durability for outdoor use but may require regular sealing and mounting to resist corrosion in humid climates. For best results, ensure your irrigation layout keeps the discharge line within the recommended gauge and use appropriate fittings for a leak-free connection.
GOULDS GT15 IRRI-Gator Self-Priming Pump
The GOULDS GT15 IRRI-Gator is a self-priming centrifugal pump designed for simple maintenance and dependable performance. Its self-priming design helps start irrigation without manual priming, which is valuable in systems with longer suction runs. The pump is fully serviceable, allowing routine component replacement to extend life. It also features an FDA-compliant impeller option, which can be important for certain irrigation setups or water quality concerns. While it emphasizes serviceability, users should verify voltage compatibility with their local supply and ensure proper priming after any service work.
Flotec FP5172 Pump Sprinkler 1.5Hp
Flotec FP5172 is a self-priming, corrosion-resistant sprinkler pump with high capacity for larger sprinkler systems. It supports up to 30 sprinkler heads and offers dual voltage operation for 115/230 V. The rugged construction uses fiberglass-reinforced thermoplastic for durability, and it handles water temperatures up to 140 °F (60 °C). This model suits homeowners seeking a robust, versatile pump for multiple zones and a wider sprinkler footprint, with emphasis on longevity and multi-voltage flexibility.
AQUASTRONG 1.6 HP Portable Shallow Well Pump
The AQUASTRONG 1.6 HP portable pump is built for mobility and high flow in shallow wells and irrigation tasks. It claims a 164 ft head maximum with a 1320 GPH flow at moderate head, making it suitable for medium-sized lawns or gardens where portability is beneficial. The stainless steel casing and aluminum motor housing enhance corrosion resistance and durability. It includes an automatic thermal overload protector and an automatic shutoff when water runs dry, helping safeguard the motor. It’s not a self-priming unit, so users must fill the pump before operation.
WAYNE PLS100 1 HP Portable Sprinkler Pump
The Wayne PLS100 is a portable 1 HP sprinkler pump designed for lawn care and temporary irrigation tasks. Its stainless-steel exterior provides corrosion resistance, and the safe on/off switch with a carrying handle enhances portability. The 120-volt motor is fan-cooled for continuous duty, delivering water up to 20 ft with a 1″ NPT suction and discharge. A standard 3/4″ garden hose adapter is included, making quick connections straightforward. This unit is well-suited for seasonal irrigation or temporary setups where mobility is a priority.
Red Lion RL-SPRK100 Sprinkler Pump
The Red Lion RL-SPRK100 is a 1 HP sprinkler pump featuring a robust cast iron housing and a glass-filled thermoplastic impeller for durability. It supports dual voltage (115/230 V) and is factory set at 230 V, with an option to switch as needed. One-time priming minimizes routine maintenance after installation. This pump emphasizes longevity and consistent performance, making it a solid choice for homeowners who want a dependable, long-lasting unit for lawn irrigation or garden watering.
Red Lion RJS-100-PREM 1 HP
The Red Lion RJS-100-PREM is a premium cast iron shallow well jet pump rated at 1 HP with a flow of up to 23 GPM. It features a 1-1/4” FNPT suction intake and 1” FNPT discharge, designed to deliver steady water pressure for small to mid-size irrigation zones. The rugged housing and glass-filled thermoplastic impeller contribute to reliability and efficiency. It includes a starting capacitor for improved priming and performance, and meets CSA standards for use in the USA and Canada. This model suits homeowners prioritizing robust construction and predictable startup power.
Buying Guide: Key Purchase Considerations
- Flow vs. head: Match GPM and maximum head to your sprinkler layout. Higher GPM is beneficial for multiple zones, while head height affects lift requirements.
- Voltage options: Dual-voltage models offer flexibility if you upgrade power or relocate. Ensure the unit’s voltage aligns with your breaker capacity and wiring.
- Priming: Self-priming designs simplify installation on longer suction runs. For non-priming units, plan for manual priming or automatic priming with compatible accessories.
- Construction: Cast iron housings often indicate durability for outdoor use, while thermoplastic impellers can reduce weight and cost but may differ in wear characteristics.
- Port sizing: Check suction and discharge fittings (NPT sizes) to ensure compatibility with existing lines and adapters.
- Durability and serviceability: Look for pumps with replaceable impellers, diffusers, and capacitors, especially for long-term maintenance.
- Portability vs. fixed install: Portable pumps are ideal for temporary setups; fixed-install models provide steady performance for a permanent irrigation system.
- Water quality: Impeller design and material should accommodate your water—well water often contains particulates that can wear pumps faster.
Practical buying tips
When evaluating options, consider your garden size, the number of zones, and the typical irrigation run time. If you have a shallow well or surface water source, a robust jet or centrifugal unit with good suction capabilities is essential. For larger properties, prioritize higher GPM and reliable electrical performance. Always verify warranty terms and confirm that the pump’s voltage and fittings are compatible with your existing system.
Comparative considerations
Red Lion models emphasize durability and consistent prime with options for dual voltage, making them strong all-around candidates. AQUASTRONG pumps offer higher GPH and dual voltage, which can benefit larger landscapes, though some models may be more complex to install. Flotec and Goulds provide a balance of convenience and serviceability, with features like self-priming and FDA-compliant components that enhance reliability in varied water conditions. Wayne’s portable PLS100 adds mobility for seasonal irrigation tasks, ideal for renters or seasonal properties.
