Summary notes: The AQUASTRONG unit emphasizes high flow with a 2″ suction and 1.5″ discharge, suited for larger lawn irrigation runs. Red Lion models combine rugged cast iron with robust priming features, offering dependable performance in varied water quality. The Wayne WLS200 focuses on high-volume outdoor needs, while Goulds presents a reliable, self-priming option suitable for multiple irrigation configurations. All selections run on 230 V in typical U.S. installations, with attention to priming requirements and durability.
AQUASTRONG 2 HP Shallow Well Jet/Centrifugal Pump
The AQUASTRONG 2 HP pump combines jet and centrifugal pumping to deliver strong output for lawn sprinklers and garden irrigation. Features include a 5200 GPH maximum flow and a maximum head of 108 ft, supported by a 2″ NPT suction and 1-1/2″ NPT discharge. A reinforced impeller and diffuser optimize efficiency, while the 230 V motor provides solid power for residential irrigation systems. Suitable for both shallow wells and surface water applications, this model aims to balance power with reliability for mid-sized irrigation zones.
Red Lion RL-SPRK-200-BR, 2 HP
Red Lion’s RL-SPRK-200-BR is built for tough conditions with a rugged cast iron pump housing and a brass impeller, designed to handle abrasive water sources. The unit runs on 230 volts and features a capacitor-run PSC design with thermally protected operation and CSA listing. No additional priming is required after the initial fill, simplifying installation and maintenance. This model emphasizes longevity in challenging environments such as ditch water or reservoirs exposed to the elements.
Red Lion RL-SPRK200 230V 2 HP
This Red Lion model features a cast iron housing paired with a glass-filled thermoplastic impeller, designed for both well and lake water scenarios. The 230 V motor and PSC design provide reliable performance with a one-time priming requirement—no ongoing priming needed after the initial setup. CSA listing adds an extra layer of verification for US and Canadian markets. It is suitable for homes with challenging water sources but requires correct voltage matching to ensure optimal operation.
WAYNE WLS200 – 2 HP
Wayne’s WLS200 focuses on outdoor resilience and high-volume transfer, with up to 4,200 GPH flow and a heavy-duty cast iron volute. The 2” NPT suction and 1-1/2” NPT discharge ports optimize flow for larger irrigation zones, with factory-set 230 V operation. The design emphasizes durability against outdoor exposure, making it a solid choice for extended irrigation seasons where reliable water distribution is essential.
Goulds GT20 IRRI-Gator 2 HP
The Goulds GT20 IRRI-Gator self-priming centrifugal pump offers 2 HP performance with a 230-volt motor and built-in overload protection. It features 1 1/2″ NPT suction and discharge connections, making it a flexible choice for lawn sprinkling, irrigation, and even some water-transfer applications. The self-priming capability enables easier setup and reliable operation after initial priming, particularly useful in systems with variable water sources or height differentials.
Buying Guide
Key purchase considerations help tailor a 2 HP sprinkler pump to your site and needs:
- Water source and head: Assess maximum head (feet) needed and total dynamic head for sprinklers. Pumps with higher head ratings support taller sprinkler grids or longer pressure runs.
- Port sizes and layout: Ensure suction and discharge ports match your piping (commonly 2″ NPT suction and 1-1/2″ discharge in many 2 HP units). Consider the layout and whether you need dual-voltage capability for future flexibility.
- Durability and materials: Cast iron housings offer rugged durability for outdoor use, while thermoplastic impellers may reduce weight but still provide strong flow. Brass impellers resist wear in abrasive water conditions.
- Priming requirements: Some models are primed once and then run without re-priming; others are self-priming, which is beneficial when water is from a shallow source or when the pump is installed above the waterline.
- Electrical considerations: Verify voltage availability (typically 230 V in the US) and circuit protection. Check for thermal protection and CSA/UL listings for safety compliance.
- Maintenance and parts availability: Look for readily available impellers, gaskets, and seals. Brands with established replacement parts reduce downtime.
- Noise and vibration: Outdoor pumps can generate noise; check for balanced rotors and robust mounting options to minimize disturbance in residential areas.
- Warranty and service: A longer warranty and accessible service networks can reduce long-term ownership cost and downtime.
- Cost of ownership: While 2 HP pumps deliver strong performance, consider efficiency (HP-to-flow ratio) to estimate running costs over time, especially in regions with extended irrigation seasons.
Across these models, consider your water source quality, desired irrigation area, and future-proofing needs (voltage compatibility and potential expansion). For challenging sources or larger lawns, a model with higher GPH and durable materials may offer better long-term performance. For simpler setups, self-priming or dual-voltage options provide flexibility and ease of installation.
