Stenner™ 45/85 (single head) & 100/170 (dual head) Classic Series Peristaltic Metering Pumps (also called Chemical Feeders) are automatically self-priming. The 3-point roller assembly provides a positive 2-point seal on the pump tube at all times. This eliminates the need for anti-siphoning valves and diaphragms. The pumps are available LOW PRESSURE and HIGH PRESSURE configurations and in FIXED RATE and ADJUSTABLE RATE styles. The fixed rate pump has no output adjustment, whereas the adjustable rate is just that - adjustable. More Information About How Stenner Pumps are Superior
