812739 Gear Reducer SK72-W 4.85:1 1750/361 RPM

Introducing the 812739 Gear Reducer by Blackmer, model SK72-W, featuring a 4.85:1 ratio designed for industrial pump applications.

The 812739 Gear Reducer is constructed with high-strength, corrosion-resistant materials, including precision-machined gears made from durable steel to ensure long-term performance in demanding environments. It is engineered to convert an input speed of 1750 RPM to an output speed of approximately 361 RPM, making it suitable for applications requiring specific speed reduction for positive displacement and sliding vane pumps.

Dimensions include a gear reducer with a flange mounting pattern compatible with standard pump configurations, and an input/output shaft diameter of specified sizes to match common motor and pump fittings. The unit weighs approximately [insert weight], with external dimensions designed for straightforward installation in existing systems. It supports a maximum torque capacity of [insert torque], providing reliable power transmission.

Key features include a precisely machined gearset with a gear ratio of 4.85:1, a 1750/361 RPM compatibility, and an oil bath lubrication system ensuring smooth operation. The gear reducer features sealed bearings and protective seals to withstand exposure to common industrial fluids and contaminants. Its corrosion-resistant finish extends service life in harsh environments. The unit allows for easy lubrication, with oil fill ports conforming to manufacturer specifications and a breather vent for pressure equalization.

Use cases for the 812739 Gear Reducer include upgrade or replacement of existing pump drive systems, especially for applications involving positive displacement and sliding vane pumps in chemical, water treatment, and industrial fluid handling. It is ideal for operations requiring reliable, efficient speed reduction and torque transmission within budget constraints, offering durable performance without frequent maintenance.

This gear reducer is shipped with the necessary mounting hardware, oil fill plug, and sealing components. Not included are the motor and pump, which must be compatible with the reducer’s shaft sizes and mounting pattern.

Care instructions involve regular oil checks and top-offs according to the manufacturer's maintenance schedule, along with periodic inspection for wear, misalignment, and seal integrity. The gear reducer includes a manufacturer’s warranty covering defects in materials and workmanship, ensuring ongoing reliability.
