The Fisnar 5-Gallon Pail Pump is a high-performance fluid dispensing system designed to deliver medium- to high-viscosity materials directly from standard 5-gallon (20-liter) pails. Featuring a powerful 20:1 pressure ratio, this pump system ensures air-free, consistent dispensing of sealants, adhesives, silicones, and greases in industrial and automated production environments. It is built to handle continuous-duty cycles and integrates with Fisnar’s range of dispensing valves and automation systems.

Key Features:
*High-output 20:1 ratio for efficient material dispensing
*Designed for 5-gallon pail compatibility (20 kg capacity)
*Integrated follower plate to ensure complete material evacuation
*Smooth, low-pulse operation for precise and repeatable dispensing
*Air-ram assist reduces operator effort and improves control
*Compatible with a wide range of fluids including silicones, greases, and pastes
*Robust, industrial-grade construction for long service life
*Easily integrates with automated and manual dispensing setups
