Ocmis OF 83/2SP PTO Driven Centrifugal Pumps

Overview

The Ocmis OF 83/2SP is a professional PTO-driven centrifugal pump engineered in Italy specifically for agricultural irrigation applications requiring reliable fresh water lifting and distribution. Manufactured by Ocmis, a specialist in irrigation equipment technology, this tractor-mounted pump delivers the hydraulic performance demanded by modern farming operations whilst maintaining the mobility and flexibility essential for efficient field irrigation. As a clean water centrifugal pump, the OF 83/2SP is optimised for handling fresh water sources, transforming tractor power into consistent irrigation flow through proven centrifugal force technology.

What distinguishes the OF 83/2SP within the Ocmis range is its dual-stage configuration, indicated by the "2SP" designation, which enables higher pressure generation compared to single-stage alternatives whilst maintaining compact dimensions suitable for field transport. The centrifugal impeller design has been engineered to balance immediate hydraulic response with sustained performance across extended irrigation sessions, reducing wear and minimising downtime. The pump incorporates a mechanical seal system designed for fresh water service, coupled with a cooling arrangement that protects critical components during prolonged operation. This combination of two-stage pressure capability and agricultural-duty construction makes the OF 83/2SP particularly suited to irrigation scenarios requiring both adequate flow volumes and sufficient delivery pressure to supply sprinkler systems or traverse moderate elevation changes.

Key Features & Benefits

• Two-Stage Centrifugal Design: The dual impeller configuration generates higher discharge pressures than single-stage pumps, enabling effective operation of travelling irrigators, sprinkler lines, and overhead systems that demand both volume and pressure, all whilst maintaining reasonable rotational speeds that extend component service life.
• PTO-Driven Power Transmission: Direct coupling to the tractor's power take-off shaft eliminates the need for separate engine units, reducing initial investment, minimising maintenance requirements, and ensuring immediate availability whenever the tractor is operational, making this pump ideal for farms where mobility between irrigation sites is essential.
• Fresh Water Optimised Construction: Materials and sealing arrangements are specifically selected for clean water service, providing reliable long-term performance in irrigation applications whilst avoiding the cost penalties associated with abrasive-duty components unnecessary for fresh water pumping, delivering optimal value for irrigational use.
• Mechanical Seal Protection: The sealed pump chamber prevents external contamination from entering critical clearances between rotating and stationary components, maintaining hydraulic efficiency throughout the season whilst reducing the frequency of seal replacement compared to packing-based systems exposed to field dust and debris.
• Integrated Cooling System: Dedicated cooling arrangements prevent thermal degradation of seals and bearings during extended pumping sessions typical of agricultural irrigation, protecting component integrity even when ambient temperatures are elevated during peak growing season demand periods.
• Compact Agricultural Profile: The pump's dimensions and mounting configuration have been developed specifically for tractor installation and field transport, allowing navigation through orchards, vineyards, and row crops without excessive overhang whilst providing stable weight distribution that maintains tractor handling characteristics.
• Italian Engineering Standards: Manufacturing in Italy under Ocmis quality protocols ensures precision machining of impellers and housings, delivering the tight tolerances necessary for sustained hydraulic efficiency and the dimensional accuracy required for vibration-free operation across the PTO speed range.
• Accessible Maintenance Design: Critical wear components and inspection points are positioned to allow routine servicing without complete disassembly, reducing downtime during the irrigation season and enabling farmers to perform basic maintenance tasks with standard workshop tools and equipment.

Technical Specifications

Ideal Applications

• Travelling Irrigator Supply: The two-stage pressure capability makes the OF 83/2SP well-suited for powering hose reel and linear move irrigation systems that require sustained pressure to operate effectively across large field areas whilst maintaining consistent application rates.
• Sprinkler System Operation: Provides the pressure and flow characteristics necessary for reliable operation of fixed and semi-permanent sprinkler installations, including impact sprinklers and micro-sprinkler arrays used in orchards, vineyards, and field crops requiring overhead irrigation distribution.
• Water Transfer Between Reservoirs: The combination of mobility and fresh water efficiency makes this pump ideal for transferring irrigation water from rivers, canals, or storage ponds to field-edge reservoirs or elevated tanks, enabling strategic water positioning that reduces subsequent distribution requirements.
• Mobile Irrigation Between Fields: The PTO-driven design allows rapid deployment across multiple irrigation sites within a single operation, particularly valuable for diversified farms where different crops or field sections require irrigation at different intervals throughout the growing season.
• Fixed Irrigation Plant Integration: Can be incorporated into permanent irrigation installations where tractor power is routinely available, providing a cost-effective pumping solution that eliminates dedicated engine maintenance whilst maintaining operational flexibility for other seasonal farm tasks.
• Emergency Irrigation Response: The immediate availability of the pump whenever the tractor is operational makes it valuable for responding to unexpected irrigation needs caused by equipment failures elsewhere in the system or during critical crop development periods when irrigation interruption must be minimised.
