Description

790268 Switch-Low Oil N7 by Blackmer

The 790268 Switch-Low Oil N7 by Blackmer is an electrical safety switch designed specifically for use with Blackmer positive displacement and sliding vane pumps. It functions as an oil level monitoring device to prevent pump operation when oil levels are too low, thereby protecting the pump from damage and ensuring reliable operation. The switch assembly is constructed with durable, corrosion-resistant materials suitable for industrial environments.

Manufactured with high-quality electrical contacts and a robust housing, the 790268 Switch-Low Oil N7 measures approximately 4 inches in height, 2.5 inches in width, and 1.2 inches in depth, fitting standard pump configurations. It is compatible with Blackmer pump models that require an oil level safety interlock, and it integrates easily into existing pump control systems. The switch is rated for temperatures up to 150°F (65°C) and voltages up to 250 VAC, supporting reliable operation across various industrial conditions.

Key features include a pressure-sensitive switch mechanism, a manual reset function after activation, and a connection port compatible with standard electrical wiring. The switch provides a visual indicator when activated, alerting operators to low oil levels, and prevents pump startup until the issue is resolved. It is suitable for medium to high viscosity oils, and its design minimizes false activations caused by oil contamination or sludging.

This 790268 Switch-Low Oil N7 is ideal for use in chemical processing, refineries, and other industrial applications where maintaining correct oil levels is critical for pump longevity and safety. It is especially recommended for operations with budget constraints, seeking reliable oil level protection without high-cost monitoring systems. The switch is intended for use with Blackmer pumps, making it suitable for replacement or upgrade in maintenance procedures.

Each unit ships with the switch component and installation hardware. Not included are additional wiring connectors or mounting brackets, which are required for complete installation. The switch requires periodic inspection and testing; cleaning involves wiping with a damp cloth, and it should be checked annually for proper operation. The component is backed by a standard manufacturer's warranty against defects within a one-year period from purchase.
