The Stenner 45MHP2 (45MJH1A1STAA) adjustable chemical dosing pump is engineered for accurate, low-flow chemical injection in water treatment and industrial systems. This peristaltic dosing pump delivers up to 3 GPD at 100 PSI and operates on 115 VAC, making it ideal for applications that require steady, controlled chemical feed.
Its peristaltic, tube-based design eliminates valves and diaphragms, which reduces clogging and simplifies maintenance. In addition, the adjustable output allows operators to fine-tune dosing rates as system conditions change. The compact and rugged construction supports reliable operation in continuous-duty environments with limited installation space.
