Hunter SRM-04 4 in. Adjustable Rotor Sprinkler (10 cm Pop-Up)

The Hunter SRM-04 is a compact, short-range gear-drive rotor designed as an efficient alternative to spray heads. With a 10 cm (4 in) pop-up, the SRM combines precise, low-precipitation coverage with durable construction for tight turf areas and narrow landscape strips.

• Adjustable arc from 40° to 360° for part- and full-circle coverage, set through the top for quick field adjustments.
• Rack of six water-efficient nozzles (0.50–3.0) lets you fine-tune radius and flow to match site conditions.
• Radius range approximately 4.3–10.4 m (14–34 ft) with radius adjustment to prevent overspray onto paths and driveways.
• Operating pressure 1.4–7.0 bar (140–700 kPa); flow range 0.08–1.0 m³/hr (1.4–16.7 L/min).
• Water-lubricated gear drive and QuickCheck™ arc mechanism provide quiet, reliable operation and easy verification of arc settings.
• Compact 10 cm pop-up height and small exposed diameter make the SRM ideal where space is limited.

Installed alone or paired with larger rotors, the SRM-04 reduces the number of sprinklers required while delivering consistent, efficient irrigation in residential and commercial landscapes. Replace nozzles or adjust radius on-site to optimize uniformity and conserve water.
