Stenner Peristaltic Metering Pumps - Single Head Adjustable Output ( 3GPD/ 25PSI max)

Single Head Adjustable Output Metering Pump • 25 psi ( 1.7 bar) • max 3 gpd ( 11 lpd) How It Works Stenner’ s adjustable metering pump is built with three detachable components: the motor, feed rate control, and pump head. Outputs are dependent upon three factors: the rpm of the motor gears, the percentage setting on the feed rate control, and the size of the peristaltic pump tube. All Stenner metering pumps have a 3-point roller design in the pump head, which acts as a check valve to prevent back flow, siphoning, overdosing and loss of prime. The motor shaft rotates at a fixed rpm which drives the adjustable feed rate control to intermittently engage the roller assembly within the pump head. The chemical solution in the pump tube is captured between the rollers as they rotate and compress the tube. As the rollers advance, the squeezed tube section regains its original form and generates a vacuum, creating the self-priming feature that delivers a constant flow unaffected by the outlet pressure. Advantages • Self-priming up to 25 feet and does not lose prime • Can pump off-gassing solutions • Solutions contained in tube, not exposed to pump components or air • Subassemblies fit together without tools; easy service or conversion to another model • Pump head universal to all Stenner pumps • Can run dry without damage • Will not clog from dirt or debris • Reproducible outputs within 2% • Adjustable feed rate control from 5% -100% in 2.5% increments • Pump tubes accept a variety of chemicals 45M1 Classic Series A rotating assembly of rollers compresses a flexible tube within a housing to create a vacuum to lift a chemical solution. The self-priming peristaltic pump is also referred to a hose, tube or dosing pump. 45M1 Classic Series Specifications Summary Outputs @ 60Hz Gallons per day: 0.2 to 3.0 Gallons per hour: 0.01 to 0.13 Liters per day: 0.8 to 11.4 Liters per hour: 0.03 to 0.48 Ounces per minute: 0.02 to 0.27 Milliliter per minute: 0.56 to 7.92 Outputs @ 50Hz Liters per day: 0.6 to 9.1 Liters per hour: 0.03 to 0.38 Milliliters per minute: 0.31 to 6.32 Discharge Pressure 0-25 psi ( 0-1.7 bar) Voltage 120V 60Hz; 220V 60Hz 230V 50Hz; 250V 50Hz International Motor shaded pole; 26 rpm; 1/ 30 HP Suction Lift 25' ( 7.6 m) Maximum Operating Temperature 125° F ( 52° C) Amp Draw 1.7 120V; 0.9 220V, 230V, 250V Dimensions ( l x w x h) 10.6 x 5.3 x 6.0 in ( 26.9 x 13.4 x 15.2 cm) Shipping Weight 9 lbs ( 4 kg) Materials of Construction All Housings: Lexan® polycarbonate plastic Pump tube & check valve duckbill: Santoprene® FDA approved Suction/ discharge tubing & ferrules ( 1/ 4" & 6 mm) : LDPE polyethylene, NSF/ FDA approved Tube fittings, connecting nuts, check valve fitting, weighted strainer: Type 1 Rigid PVC-NSF listed All fasteners: Stainless Steel Lexan® is a registered trademark of General Electric.
