909706 Lockwasher, 1/2" Split Lock

Product Identification

The 909706 Lockwasher, 1/2" Split Lock by Blackmer, is a specialized locking component designed to prevent loosening of threaded fasteners in pump assemblies. It is used to secure threaded connections in positive displacement and sliding vane pumps, ensuring consistent and reliable operation.

Materials and Construction

The 909706 Lockwasher is manufactured from durable steel, providing high tensile strength and resistance to fatigue. Its split lock design allows for strategic deformation when tightened, creating a locking tension that maintains the integrity of fastened joints under operational vibrations and thermal fluctuations.

Dimensions and Compatibility

This lockwasher features a 1/2-inch internal diameter, compatible with fasteners of equivalent size. It measures approximately 0.75 inches (19.05 mm) in outer diameter, with a thickness of around 0.05 inches (1.27 mm). It fits standard 1/2-inch threaded bolts or screws used in Blackmer pump assemblies.

Key Features

• Manufactured from high-strength steel for durability and corrosion resistance
• Split design enables secure locking by deformation of the washer when tightened
• Universal for 1/2-inch threaded fasteners commonly used in pump assemblies
• Designed to maintain maximum locking tension under vibration and thermal cycling
• Provides a reliable locking solution in high-demand industrial settings
• Ensures safety and resistance to loosening over the lifespan of the pump

Use Cases and Budget Considerations

The 909706 Lockwasher is ideal for securing threaded fasteners in Blackmer pumps operating in chemical processing, water treatment, and industrial fluid transfer applications. It is suited for dedicated maintenance teams and engineers seeking a cost-effective, reliable locking solution. This lockwasher is essential for preventing fastener loosening, which can lead to pump failure or leaks, ultimately reducing maintenance costs and downtime.

Designed for budget-conscious industrial facilities, it provides a durable, proven locking method without the expense of more complex locking devices. Its compatibility with standard 1/2-inch fasteners makes it an accessible choice for routine pump assembly and maintenance.

Inclusions and Exclusions

Shipments include a package of one 909706 Lockwasher, 1/2" Split Lock. No additional fasteners or tools are included. It is intended for use with compatible threaded fasteners; purchase additional lockwashers as needed for multiple connections.

Care and Maintenance

The 909706 Lockwasher requires no special maintenance beyond routine inspection for corrosion or damage. It can be cleaned with standard shop tools and should be replaced if deformed or compromised. Proper torque application during assembly maintains locking effectiveness. This lockwasher does not come with a warranty; replacement is recommended if it shows signs of wear or damage.
