2500 Series dispense system with Drive assist

The 2500 DA Drive Assist functions the same as the standard 2500 Double Acting. However the pneumatic Drive Assist cylinder increases the unit’s capability in processing high viscosity materials. In most applications the use of the drive assist eliminates the need for feed pumps.

Standard Features

• Positive displacement piston metering with positive ported, 4-way flow directional valves (NOT check valves) maintains very accurate ratio.
• Double-acting design for on-demand dispensing with no interruption for reloading the metering cylinders.
• Pneumatic Drive Assist increases the unit's capability in processing air-free, high viscosity materials. In most applications the drive assist cylinder eliminates the need for feed pumps.
• In-line design prevents racking or side-loading of the metering pistons. The in-line configuration assures exact ratio regardless of viscosity differences.
• No-purge, snuff-back mix/dispense assembly eliminates solvent purging and hazardous waste.
• Pump feeding from the original shipping containers or vacuum/holding tanks.
• Abrasion-resistant metering cylinder, seals, and hardware.
• Rugged, heavy-duty construction.
