55 Gallon One Component Drum Pump for Expansion Joint Filling

AST SP 55-C: The Ultimate Single Component Drum Pump for Expansion Joint Filling & Sealing

Engineered for High-Volume Industrial Applications

When it comes to high-volume joint filling and sealing, the AST SP-55 Single Component Drum Pump sets the industry standard. Designed for professionals in need of a robust, high-performance dispensing system, the SP-55 offers unparalleled efficiency and precision.

Note: the SP-55 is a higher output version of the AST SP-5. 

High-Volume Dispensing: Unmatched Throughput

The AST SP-55 is engineered for speed and efficiency. With a flow rate of up to 2 gallons per minute—dependent on viscosity—this drum pump is built to handle high-volume applications. Its adjustable flow rate allows for precise control, making it an indispensable asset for large-scale, industrial operations.

Extreme Pressure Capabilities: Built for Tough Jobs

With fluid pressures up to 3,000 psi and viscosities up to 1,000,000 cps, the SP-55 is designed to tackle the most demanding joint filling and sealing tasks. Its high-pressure, self-priming feature ensures consistent, reliable performance even under extreme conditions.
