Flomotion - Model SP21 Series -Self-Priming Analyzer Sample Pump

Designed to meet the demanding requirements of continuous liquid sample delivery. Exceptional self-priming capabilities make the SP21 an ideal choice for hard-to-handle chemicals such as sodium hypochlorite, hydrogen peroxide or viscous polymers. A wide range of flow outputs can be obtained by simply changing the tubing size. One size pumphead accepts six standard tubing sizes. The spring-loaded pumphead rollers provide extended tubing life and automatically compensate for minor variations in pump tube wall thickness.
