Product Overview
The Stenner 45MHP22 is a high-pressure adjustable peristaltic dosing pump designed for accurate chemical injection applications requiring dependable output at elevated discharge pressures. Its external feed-rate dial provides a 20:1 turndown, allowing the output to be adjusted from approximately 0.25 to 5.05 L/h at 50 Hz while maintaining precise chemical dosing.
The valveless peristaltic design handles off-gassing chemicals without losing prime or experiencing vapour lock. It can also run dry without damaging the pump, making it ideal for water treatment, disinfection, industrial processing and other continuous chemical dosing applications.
The QuickPro® pump head allows fast, tool-free pump tube replacement without lubrication, reducing maintenance time and simplifying servicing. The pump is supplied with all installation accessories for quick commissioning.
