Ocmis MRR Turbine Drive Hard Hose Irrigator

Overview

The Ocmis MRR is a turbine-driven hard hose irrigator manufactured by Ocmis Irrigazione, Italy's premier irrigation equipment specialist. This robust irrigation machine combines proven turbine technology with a precision gearbox system to deliver reliable performance across a wide range of agricultural applications. Available in multiple hose configurations from 50 mm to 63 mm (1.97 to 2.48 inches) diameter and lengths up to 230 metres (755 feet), the MRR series offers flexibility for small to medium-sized field irrigation projects requiring dependable water distribution.

What distinguishes the MRR from conventional hard hose irrigators is the proprietary Turbo Speed system, which significantly reduces turbine load loss whilst enabling consistent machine operation even under low flow and pressure conditions. This innovative drive mechanism, combined with external turbine by-pass flanged directly to the gearbox, ensures optimal energy efficiency and extended component life. The complete machine benefits from epoxy resin coating and polyurethane paint finish for exceptional corrosion resistance, whilst the galvanised raingun trolley and unadulterated polyethylene hose deliver years of trouble-free service with minimal maintenance requirements.

Key Features & Benefits

Turbo Speed System: Reduces turbine load loss and enables variable speed operation even with low inlet pressures and flow rates, providing operational flexibility across diverse field conditions and water supply scenarios.
Turbine Flanged on Gearbox with External By-Pass: Direct turbine mounting eliminates connection losses whilst the external by-pass allows precise flow control and protection against overpressure, extending component lifespan and reducing maintenance interventions.
Advanced Hose-Guide System: Ensures uniform hose winding and prevents overlapping or misalignment during retraction, eliminating hose wear and extending service life whilst maintaining consistent rewind tension.
Power Take-Off for Fast Retraction: Enables rapid machine retrieval at the end of irrigation cycles or during adverse weather conditions, significantly reducing labour time and allowing quick field access for subsequent operations.
Triple-Wheel Chassis Configuration: Front wheel (13.5.00 x 6 inches) and dual rear wheels (15.6.00 x 6 inches 4F) provide superior stability on uneven terrain whilst minimising soil compaction and ensuring precise tracking during irrigation travel.
Premium Polyethylene Hose Construction: Manufactured from unadulterated raw material to guarantee maximum UV resistance, flexibility, and pressure tolerance without degradation from recycled additives that compromise performance and longevity.
Epoxy Resin and Polyurethane Coating System: Dual-layer protection provides exceptional corrosion resistance against fertiliser-laden water, chemical exposure, and environmental weathering, ensuring decades of reliable service in demanding agricultural environments.
Galvanised Raingun Trolley: Hot-dip galvanisation provides permanent rust protection for the critical raingun mounting and travel assembly, eliminating maintenance painting requirements and ensuring smooth operation throughout the machine's service life.
Integrated Pressure Monitoring: Factory-installed pressure gauge enables real-time system monitoring for optimal nozzle performance verification, leak detection, and pressure regulation to prevent under or over-application of irrigation water.
Comprehensive Safety Guards: Fully compliant protective equipment shields all rotating components and pinch points, meeting international safety standards whilst allowing convenient access for routine maintenance and adjustments.

Ideal Applications

Row Crop Irrigation: Ideal for maize, soybean, cotton, and vegetable production where medium-throw irrigation coverage (up to 755 feet hose length) matches field dimensions and row spacing requirements.
Pasture and Forage Establishment: Excellent for establishing and maintaining permanent pastures, hay fields, and silage crops where reliable water distribution supports consistent germination and growth throughout the growing season.
Orchards and Vineyard Frost Protection: Suitable for under-canopy irrigation and overnight frost protection applications where the HYDRA raingun provides adjustable throw patterns and precipitation rates to match crop requirements.
Small to Medium Field Parcels: Optimised for properties with irregular field shapes or multiple smaller paddocks where the compact chassis dimensions and flexible hose configurations enable efficient irrigation coverage without oversized equipment investment.
Supplemental Irrigation Systems: Perfect for augmenting centre pivot or lateral move systems in field corners, odd-shaped areas, or during peak demand periods when permanent irrigation infrastructure requires additional capacity.
Contract Irrigation Services: The power take-off fast retraction system and robust construction make this machine ideal for contractors serving multiple properties who require quick relocation and dependable performance across diverse terrain and crop types.
