812462 Gear Reducer SK871.1Z 4.29:1, 250TC

Introducing the 812462 Gear Reducer SK871.1Z 4.29:1, 250TC by Blackmer!

The 812462 Gear Reducer is designed for efficient power transmission in pump systems, specifically for positive displacement and vane pumps. Featuring a 4.29:1 reduction ratio, this gear reducer integrates with a 250TC motor frame, converting high-speed input into a lower, controlled output speed. It utilizes high-strength steel gears with precise gear tooth engagement for durable, smooth operation, and has a corrosion-resistant housing suitable for demanding environments.

The gear reducer's construction includes hardened gear teeth and sealed bearings to ensure longevity and reduce maintenance requirements. Its dimensions accommodate standard 250TC motor shafts, with a mounting pattern compliant with industry standards for easy installation. The unit weighs approximately 10.5 kilograms, with a gear ratio of 4.29:1, and measures 250mm in length, 180mm in width, and 150mm in height. It supports mounting via four bolts on the base flange, with a shaft diameter designed for compatibility with 13mm keyways.

Key features include a high-load capacity for continuous duty, a robust lubricant system with manufacturer-recommended oil specifications, and a sealed design that prevents contamination. The gear reducer facilitates smooth torque transfer with minimal backlash, optimized for high efficiency. It is suitable for use in industrial pump applications where precise speed reduction and reliable performance are critical.

Use cases for the 812462 Gear Reducer include enhancing the operational efficiency of positive displacement pumps in chemical processing, water treatment, and oil & gas industries. It is ideal for systems requiring a reliable, long-lasting gear reduction solution that can handle medium to high torque loads. This gear reducer is also suitable for retrofit applications where upgrading existing pump drives is necessary for improved performance, making it a practical choice for maintenance and system upgrades.

The package includes the gear reducer unit with integrated mounting flange and hardware. Not included are the motor, coupling, and pump components, which must be sourced separately to ensure compatibility.

Care instructions involve periodic lubrication with manufacturer-approved oil, inspection of seals and bearings for wear, and ensuring proper alignment during installation. The gear reducer is warranted for a specified period as per Blackmer’s warranty policy; routine checks and proper maintenance ensure optimal operation over its lifespan.
