The GRACO 24K466 is an alarm pump accessory designed for use with GBL 7500 box lubricator pumps. It is constructed from robust materials suitable for industrial environments and is intended to monitor shaft rotation and low lubricant levels, providing an alarm signal when either condition is detected. This helps prevent equipment damage due to insufficient lubrication or unexpected shaft stoppage.

Key Features:

• Alarm Pump (Shaft Rotation/Low Level Alarm)
• 24K466
• Sensor output opens at 100–200 psi (0.68–1.4 MPa, 6.89–14 bar); monitor block maintains pressure at 100–110 psi (7.0–7.7 kg/cm²) during operation, bleeds down to 50 psi (3.5 kg/cm²) within 45 seconds after pump stops
• GBL 7500 Box Lubricator Pumps
• Mounts in a pump slot, reducing maximum pump quantity by one
• Non-adjustable monitor block
• Always mounted in the last pump station at the end of the reservoir opposite the drive end
• Superior roller bearing design for improved rotation and reduced wear
• Dynamic captured seal design for better sealing and reduced contamination
• Stainless steel piston and spring for corrosion resistance and consistent output

Applications:
Used in automatic lubrication systems for industrial, mining, energy, agriculture, and transportation equipment to monitor and alarm for shaft rotation stoppage or low lubricant levels.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Mount the alarm pump in the last pump station at the end of the reservoir opposite the drive end
• Reduce maximum pump quantity by one when installing the 24K466 alarm pump
• Install a user-supplied alarm pressure switch in the sensor output port, set to trigger at 50 psi (3.5 kg/cm²) falling
• Ensure proper electrical connections according to the equipment’s voltage requirements (15 amps at 115/230 or 480 VAC, 0.5 amps at 125 VDC, 0.25 amps at 250 VDC)
• Regularly inspect the alarm pump and associated wiring for signs of wear or damage
• Monitor system pressure and alarm functionality during routine maintenance
• Replace worn or damaged components with genuine GRACO parts
