Stenner Classic Series Adjustable Peristaltic Pump – Model 45M5

Reliable, Precise Chemical Injection for Pools, Water Treatment, and More

The single head adjustable is an ideal choice for treating problem water, it can inject solutions for pH control or to oxidize iron, hydrogen sulfide or manganese for removal by filtration. Disinfection, pH control or adjustment, corrosion and scale control, and oxidation are common water treatment applications found in markets such as Water Conditioning, Industrial Process, Water and Wastewater, and Cooling Towers. The pumps are widely popular in the commercial pool industry for sanitizing swimming pool water or maintaining the equipment.

Key Features:

• 3-point roller design assists in anti-siphon protection
• Pump head requires no valves, allows for easy maintenance
• Self priming against maximum working pressure, foot valve not required
• Pump does not lose prime or vapor lock
• Pumps off-gassing solutions and can run dry
• Output volume is not affected by back pressure
• Injection check valve included with models rated up to 25 psi (1.7 bar)
• Easy and fast tube replacement without tools with the QuickPro® pump head
• Pump tubes and pump heads interchange between models
• The pump is built with three detachable components – the motor, feed rate control and the pump head that can be separated without tools

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.
