Description
High-Precision Chemical Dosing Pump for Reliable Water Treatment Performance and Long-Term System Efficiency
Reliable chemical dosing starts with a pump that is crafted for the job, not adapted from something else. The MEC-O-MATIC Dolphin Series Peristaltic Pump is a purpose-made peristaltic metering pump covering 0.13 to 97 gallons per day at 25 PSI, with a built-in 1–100% run-time control dial that gives operators precise feed adjustment without an external controller.
Certified to NSF/ANSI 61 by WQA, the Dolphin Series is a compliant, field-proven choice for chlorine feed, pH adjustment, fluoride, and enzyme dosing in potable water, pools, cooling towers, and industrial water treatment. Manufactured by Pulsafeeder (IDEX Corporation), it is built to run continuously in demanding environments with minimal maintenance.

Frequently Asked Questions
How does the 1–100% run-time control work?
The built-in timer cycles every 10 minutes. The dial sets the percentage of run time within that cycle. For example, 30% means 3 minutes on and 7 minutes off, delivering simple, proportional dosing without external controls or wiring.
What does NSF-61 certification mean?
NSF-61 certification confirms the pump's wetted materials are safe for potable water use. They are tested for chemical leaching and compliance. This makes the Dolphin Series suitable for municipal water, pools, and regulated applications requiring certified equipment.
Why use peristaltic technology instead of diaphragm?
Peristaltic design moves fluid through tubing only. No chemical contacts internal metal parts. This prevents vapor lock, allows dry-run operation, and simplifies compatibility. It is ideal for chlorine and pH dosing where reliability and low maintenance are critical.
How is the feeder head accessed for tube replacement?
The pump uses a twist-off polycarbonate head. It opens by hand without tools or fasteners. Tube replacement takes under five minutes, making maintenance quick and practical for remote sites and facilities with limited service time.
