Description

The 812390 Gear Reducer by Blackmer is a precision-engineered component designed to optimize pump performance across various industrial applications.

Manufactured with durable steel gearing and corrosion-resistant coatings, this gear reducer features a 5.41:1 reduction ratio and a 180TC frame size, compatible with a range of positive displacement and sliding vane pumps. Its construction ensures high torque output and reliable long-term operation in demanding environments. The unit weighs approximately 25 kilograms, with dimensions suited for integration into pump systems where space constraints are a consideration. The input shaft has a diameter of 1.5 inches with a keyway, and the output is designed to match standard coupling interfaces.

Key features include a precision-machined gear set for smooth torque transfer, sealed lubrication system for maintenance reduction, and an input/output configuration tailored for easy installation. The gear reducer operates at an input speed of up to 1750 RPM, with its reduction ratio achieving an evenly distributed torque output. This product is ideal for pump systems needing consistent speed control, durable performance, and minimal maintenance—making it suitable for chemical processing, water treatment, and industrial fluid handling. It is particularly beneficial for users seeking to optimize pump efficiency and extend equipment lifespan without exceeding their existing budget.

The gear reducer ships with a filled lubrication system, mounting hardware, and instruction manual. Not included are motors or coupling components, which must be selected according to system specifications. Proper alignment, secure mounting, and correct lubricant type as per manufacturer instructions are necessary for optimal operation.

Care instructions involve regular lubrication checks, re-tightening fasteners after initial operation, and periodic inspections of seals and gear wear. A standard warranty covers manufacturing defects for one year from purchase date, with maintenance guidelines detailed in the included manual.
