151B3109 Danfoss OMV800 gerotor hydraulic motor is an ultra-large displacement low-speed high-torque (LSHT) hydraulic motor from the Danfoss OMV series, with part number 151B3109. This product is an original dedicated drive component for mobile crushing and screening equipment such as Hartl crushing buckets. It can directly replace the original motor in the hydraulic system of Hartl crushers, ensuring reliable operation of equipment under harsh working conditions including mining, quarrying and building demolition.

As the core drive component of Hartl crushers, the 151B3109 delivers ultra-large displacement of 801.8 cm³/rev and continuous torque output of 1880 N·m, providing powerful power for crushing buckets. Adopting Danfoss advanced Geroler roller gerotor gear set and disc-type flow distribution structure, this motor efficiently converts hydraulic energy into mechanical energy to drive the jaw plates of Hartl crushing buckets to perform reciprocating motion and achieve efficient material crushing.

This product can fully replace equivalent series models including Danfoss OMV800 and 151B3109, and is also compatible with products of equivalent specifications such as White Hydraulics and Parker TG series. It is the preferred plug-and-play maintenance replacement solution for Hartl crusher users.

1. Disc Valve Distribution Technology – Industry-Leading Energy Efficiency

• Independently driven hydraulically balanced valve plate: Synchronously driven by universal shaft, precisely controls each working chamber, minimizing hydraulic and mechanical losses.
• Automatic wear compensation: Maintains high volumetric efficiency over the long term with durable and stable performance.
• Minimum pressure drop: Optimized flow channel design delivers lower pressure drop, achieving energy savings and high efficiency.
• Sustained high efficiency: Maintains excellent efficiency under high-pressure working conditions, perfectly adapted to variable-load operations of crushers.

2. Geroler Roller Gear Set – Rolling Friction, High Efficiency and Durability

• Rolling friction design: Rollers replace sliding friction, achieving mechanical efficiency far exceeding traditional Gerotor motors.
• High starting torque: Starting torque reaches more than 90% of the theoretical value, easily handling heavy-load startup.
• Low-noise operation: Optimized gear design ensures smooth and quiet operation.
• Roller-equipped gear ring: Lower frictional resistance and longer service life.
