How It Works:

The 45M5 pump features a three-part modular design—motor, feed rate control, and pump head. The rotating motor drives the roller assembly inside the peristaltic pump head, compressing and releasing the pump tube to create suction and discharge. The external dial adjusts chemical flow without changing tubing or interrupting service.

Applications:

• Pool & Spa Chemical Dosing

• Disinfection (Chlorine, Acid, etc.)

• pH and ORP Control Systems

• Water Treatment & Filtration

• Fertigation and Industrial Processes

Note: For fixed-output applications or integration with controllers and pulse meters, see the 45MF series or Stenner Proportional Feed Systems.
