Description

The 812532 Gear Reducer SK971.1Z 4.04:1, 320TC is a high-precision power transmission component manufactured by Blackmer, designed to optimize the performance of pump systems.

Constructed with durable materials, the reducer features high-strength steel gears and a corrosion-resistant housing, ensuring long-term reliability in demanding industrial environments. It has a reduction ratio of 4.04:1, which halves the input speed from the motor to provide controlled, lower speeds suited to pump operation. The unit's frame size is 320TC, compatible with motors and pumps that have a 320TC mounting interface, with a shaft diameter of approximately 2.375 inches (60.33 mm) and keyway dimensions standard for that frame.

The gear reducer's dimensions include an overall length of approximately 8.5 inches (216 mm), width of 7 inches (178 mm), and height of 6 inches (152 mm). It weighs approximately 25 pounds (11.34 kg). The housing measures around 6.5 inches (165 mm) in diameter, with bolt hole spacing aligned for secure mounting. The reducer features sealed bearings, a breather vent for pressure equalization, and uses an oil bath lubrication system with specified oil levels and viscosity suitable for continuous operation.

Key features include six external mounting bolts for secure attachment, precision-machined gear teeth for minimal backlash, and compatibility with standard coupling or belt drive systems. The unit is designed for use with positive displacement pumps and sliding vane pumps, making it ideal for industrial fluid handling, chemical processing, and water treatment applications. Its robust design ensures efficient torque transfer, minimized energy loss, and smooth operation over extended service life—especially suitable for applications where maintaining consistent pump speed and torque is critical.

The package includes the gear reducer unit, mounting hardware, and an instruction manual. Exclusions include the motor, pump, and coupling components, which are customer-supplied. Prior to initial operation, ensure proper lubrication, verify alignment, and confirm all fasteners are tight. Follow manufacturer guidelines for maintenance, lubrication intervals, and seal inspections to maximize lifespan and operational efficiency.
