Stenner 45MHP2 Adjustable Chemical Metering Pump – 3 GPD, 100 PSI, 115V
Ships in 5–10 Business Days
The Stenner 45MHP2 is a 3 GPD, 100 PSI peristaltic chemical metering pump designed for precise industrial water treatment and chemical injection applications.
The Stenner 45MHP2 (45MJH1A1STAA) adjustable chemical metering pump delivers accurate, low-flow chemical injection for water treatment and industrial applications. It is designed for systems that require precise and stable chemical control.
With a rated output of 3 GPD at 100 PSI, this 115V peristaltic dosing pump meters disinfectants, pH control chemicals, and treatment additives with consistent accuracy. Its smooth, valve-free design reduces wear and minimizes maintenance requirements.
Because operators can easily adjust the flow rate, the pump quickly adapts to changing system demand. As a result, it performs reliably in continuous-duty chemical feed systems.

Why Choose the Stenner 45MHP2 Chemical Dosing Pump?
The Stenner 45MHP2 uses proven peristaltic pump technology. Unlike diaphragm pumps, it does not use check valves or diaphragms. Therefore, it reduces clogging and simplifies maintenance.
Its compact and rugged design supports long service life in demanding environments. In addition, it operates reliably in indoor and protected outdoor installations. The adjustable output allows flexible control across low-flow dosing requirements.
Designed for Water Treatment Applications
The Stenner 45MHP2 peristaltic metering pump is commonly used in:
-
Potable water treatment systems
-
Wastewater treatment plants
-
Cooling tower chemical feed systems
-
Industrial process water systems
-
Disinfection skids
-
pH control panels
It supports accurate injection of chlorine, acids, alkalis, and compatible treatment chemicals.
Because of its compact footprint, the pump fits easily into small chemical feed panels and packaged treatment systems.
How the Peristaltic Design Improves Reliability
The peristaltic mechanism compresses tubing to move fluid. Because fluid only contacts the tube, internal components stay protected from chemical exposure.
This design:
-
Reduces clogging
-
Eliminates check valve failures
-
Simplifies maintenance
-
Improves reliability in low-flow systems
