Stenner 85MHP40 High-Pressure Adjustable Peristaltic Dosing Pump

The Stenner 85MHP40 is a high-pressure adjustable peristaltic dosing pump designed for continuous chemical injection applications requiring accurate, high-volume dosing 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 demanding chemical dosing applications.

The QuickPro® pump head allows fast, tool-free pump tube replacement without lubrication, reducing maintenance time and simplifying servicing. High-pressure models are supplied with an injection check valve and a complete installation accessory kit.
