Description
Self-Priming, Low Maintenance, Precision Chemical Feed for Water Treatment
The MEC-O-MATIC VSP Variable Speed Peristaltic Pump is a purpose-made chemical metering solution for water treatment professionals who need accurate, repeatable dosing without complex maintenance. Covering a flow range of 0.13 to 97 GPD at up to 25 PSI, the VSP handles chlorine, pH adjustment chemicals, coagulants, enzymes, and more through a self-priming peristaltic design that keeps chemicals isolated from moving parts.
Built with a chemical-resistant ABS housing and durable all-metal gearing, it is designed for demanding environments while maintaining long service life. The variable-speed gearmotor with simple potentiometer control allows precise adjustment from 10% to 100%, giving operators reliable, flexible dosing for municipal water treatment, pools, and industrial applications.

Frequently Asked Questions
How does the MEC-O-MATIC VSP handle outgassing chemicals like sodium hypochlorite?
The peristaltic mechanism continuously pushes fluid and gas through the tubing without interruption. This prevents vapor lock, maintains steady flow, and ensures accurate dosing even when handling chemicals that release gas.
How do I adjust the output rate on the MEC-O-MATIC VSP pump?
The built-in potentiometer directly controls motor speed to regulate flow output. Adjusting from 10 to 100 percent allows precise, real-time control of chemical feed rates without additional equipment.
What is the only wetted component in the MEC-O-MATIC VSP?
The peristaltic tubing is the only component in contact with the chemical being dosed. This isolates internal parts from corrosion and ensures compatibility depends only on tubing material selection.
Can the MEC-O-MATIC VSP run dry without damage?
The pump operates without fluid contact in its drive system, allowing it to run dry safely. This prevents damage during empty tank conditions and maintains operational reliability.
How long does tube replacement take on the MEC-O-MATIC VSP?
The quick-release pump head allows direct access to the tubing without tools. This design enables fast tube changes, minimizing downtime and keeping dosing systems operating efficiently.
