Dosing Pumps

Stenner Dosing Pumps

Peristaltic, or dosing pumps are a self-priming type pump that achieves pumping action by moving a system of rollers against a flexible tube. The pumped fluids (e.g., chemical feeds) are never exposed to the air or to the mechanical moving parts. The roller design prevents siphoning by providing a constant seal on the pumping tube. Stenner pumps deliver consistent output reproducibility, with no loss of prime from off-gassing solutions. Self-priming up to 25 feet, they can run dry without damage and will re-prime when the tank is filled. No foot valve or check valve is needed in the pump head. Available in Single head or Double head, Fixed or Adjustable.
