Ocmis TNO 125 L PTO Driven Slurry Centrifugal Pumps

Overview

The Ocmis TNO 125 L is a professional PTO-driven slurry centrifugal pump manufactured in Italy, specifically engineered for agricultural slurry handling and dirty water pumping operations. As part of Ocmis's L-version pump range, this tractor-mounted pump is designed for slurry and dirty water applications with a small percentage of suspended solids, providing reliable performance for irrigation activities requiring efficient liquid transfer. The TNO 125 L combines robust Italian engineering with practical functionality, delivering the ideal balance between immediate operational performance and long-term durability in demanding agricultural environments.

This pump distinguishes itself through its advanced closed high-flow impeller design, which optimises flow rates whilst handling moderately contaminated water and light slurry mixtures. The TNO 125 L features a sophisticated mechanical sealing system with silicon carbide contact faces and an external auxiliary lubrication tank, ensuring reliable operation even during extended working periods. The multiplier box incorporates an exclusive internal water circulation cooling system that dramatically extends the service life of mechanical components, whilst the high-performance helical spur gear arrangement with oil bath lubrication guarantees smooth power transmission from tractor PTO to pump shaft. The integrated double-row ball bearings and taper roller bearing assembly provide exceptional shaft support, reducing maintenance requirements and maximising operational uptime.

Key Features & Benefits

• Closed High-Flow Impeller Design: The L-version closed impeller configuration delivers exceptional flow rates for dirty water and light slurry applications with small percentages of suspended solids, maximising pumping efficiency whilst minimising wear from abrasive particles.
• Silicon Carbide Mechanical Seal with Auxiliary Lubrication: Premium silicon carbide contact faces provide superior wear resistance and extended seal life, whilst the external lubrication tank ensures continuous seal cooling and lubrication, dramatically reducing maintenance intervals and preventing costly seal failures.
• Advanced Multiplier with Helical Spur Gears: High-performance helical spur gear arrangement operates in an oil bath environment, delivering smooth, quiet power transmission whilst the unified pump shaft and driven pinion assembly supported by double-row ball bearings and taper roller bearings ensures precise alignment and extended component life.
• Exclusive Internal Water Cooling System: The multiplier box features an innovative internal water circulation cooling system that actively dissipates heat generated during operation, guaranteeing very long mechanical component life even during extended working periods under demanding agricultural conditions.
• Versatile Volute Pump Body Configuration: Single-impeller volute design with axial suction inlet and upward radial outlet position provides optimal hydraulic efficiency, with the option to rotate the suction inlet by 90° in either direction for maximum installation flexibility in diverse tractor and equipment configurations.
• Robust PTO Drive System: Direct tractor PTO connection eliminates the need for separate power sources, enabling mobile operation across multiple field locations whilst the multiplier gearing optimises pump speed for maximum efficiency regardless of tractor PTO speed variations.
• Accessible Maintenance Design: Strategic component placement and straightforward construction facilitate routine maintenance tasks, reducing downtime and enabling operators to perform field servicing without specialised tools or extensive technical training.
• Italian Manufacturing Quality: Precision manufacturing in Italy ensures consistent build quality, tight tolerances, and reliable performance, backed by Ocmis's extensive experience in agricultural pumping equipment design and production.

Technical Specifications

Ideal Applications

• Agricultural Slurry Distribution: Pumping and spreading of livestock slurry with small percentages of suspended solids for field fertilisation and nutrient management programmes across agricultural operations.
• Dirty Water Irrigation: Transfer of contaminated irrigation water from storage lagoons, settling ponds, or natural water sources containing sediment and light organic matter to irrigation distribution systems.
• Wastewater Management: Handling agricultural wastewater, dairy parlour effluent, and yard runoff with moderate solid content for transfer to treatment facilities or application areas.
• Mobile Pumping Operations: Tractor-mounted mobility enables flexible deployment across multiple field locations, drainage areas, or irrigation zones without permanent installation infrastructure.
• Lagoon and Pond Transfer: Efficient liquid transfer from storage lagoons, retention ponds, or collection tanks containing settled slurry or dirty water with minimal fibrous content.
• Seasonal Irrigation Support: Supplementary water supply for crop irrigation during peak growing seasons, drawing from alternative water sources that may contain elevated sediment or organic matter levels.
