Ocmis R3A Turbine Drive Hard Hose Irrigator

Overview

The Ocmis R3A is a turbine-driven hard hose irrigator designed and manufactured by Ocmis Irrigazione in Italy, representing one of the most popular models in the company's professional irrigation equipment range. This robust traveling irrigator combines proven turbine drive technology with the innovative Turbo Speed system, delivering reliable performance across hose configurations ranging from 82 mm to 120 mm (3.23 to 4.72 inches) in diameter and lengths from 230 m to 500 m (755 to 1640 feet). Engineered for commercial agricultural operations, the R3A offers versatile irrigation solutions with low running costs and minimal maintenance requirements.

What distinguishes the R3A from conventional hard hose irrigators is its Turbo Speed system, which significantly reduces turbine load loss while enabling a wide range of machine speeds even under low flow and inlet pressure conditions. The machine features a 6-speed gearbox flanged directly to the turbine with built-in bypass, telescopic hydraulic feet for easy positioning, and a hot-galvanized chassis paired with epoxy resin-coated reel for maximum durability. Available with either ROYAL or REFLEX rainguns depending on configuration, the R3A is appreciated worldwide by agriculturalists for its user-friendly operation and adaptability to diverse irrigation requirements.

Key Features & Benefits

Turbo Speed System: Reduces turbine load loss and enables consistent operation across a wide range of speeds, even with very low flows and inlet pressures, maximizing efficiency across varying field conditions.
6-Speed Gearbox with Turbine Flange: Provides precise control over retrieval speed with built-in bypass, allowing operators to match irrigation speed to crop requirements and soil infiltration rates for optimal water distribution.

Hot Galvanized Chassis and Turret: Superior corrosion protection through hot galvanization ensures long service life even in harsh agricultural environments, protecting your equipment investment for years.
Epoxy Resin Coated Reel: The reel receives epoxy resin coating plus polyurethane paint finish, providing exceptional protection against weathering and chemical exposure while maintaining smooth hose winding performance.
Dual Raingun Options: Comes equipped with either ROYAL rainguns (for smaller diameter hoses with nozzles Ø 16-22 mm) or REFLEX rainguns (for larger diameter hoses with nozzles Ø 24-32 mm), with complete nozzle sets included for application flexibility.
Galvanized Raingun Trolley on Variable Track Wheels: Adjustable wheel tracking accommodates different row spacings while the galvanized construction ensures durability in continuous field use.
Polyethylene Hose from Unadulterated Raw Material: Premium quality hose construction ensures consistent performance, resistance to UV degradation, and reliable service life without material compromise.
Comprehensive Monitoring Instrumentation: Includes glycerine bath pressure gauge, tachometer, and speed equalizer for precise irrigation management and troubleshooting.
Dual Water Inlet System: Galvanized double water inlet with Bauer Ø 89 mm connection for 82-100 mm hoses or Bauer Ø 108 mm for 110-120 mm hoses provides secure, leak-free connection options.
