AD81 | LMI Metering Pumps - 0.21 GPH - 250 psi - Pulse & 4-20mA Input

Designed to meet your most challenging water treatment needs

Designed specifically for commercial and industrial applications, the Excel AD chemical metering pump gives you improved electro-magnetics to meet your specific flow and pressure requirements, up to 250 psi (17.2 Bar) with capacities between .002 and 2.0 GPH (.8 to 7.6 l/h). The EXCEL AD pump provides industry solutions for more versatile chemical injection with up to 1000:1 turn-down capacity to take control of your application.

This line includes an advanced design fitting system for secure, leak-proof tubing or NPT connections. Every pump comes standard with FastPrime liquid ends. If pumping off-gassing liquids, select the (optional) AutoPrime liquid end. High-viscosity liquid ends (optional) are also available for pumping high viscosity liquids.

With an easy-to-read LCD user interface, external pacing, alarms and pulse/4-20 mA input and output capability the Excel AD pump has the power and flexibility you need to accurately perform in the harshest industrial or municipal environments.
