Standard Bellows Metering Pumps Overview Bellows metering pumps operate on a positive displacement principle. Pumps are designed to displace both corrosive and noncorrosive fluids. Accurate to ± 0.5% from stroke to stroke, when pump is set 50% to 100% of full stroke. Discharge pressure is maintained over the entire flow range of the pump. Poppet valves are used to prevent back flow; and springs are available to provide a positive shutoff, preventing siphoning through the pump in applications where a positive suction head exists. Typical applications include film and x-ray processors, silver...

Bellows Metering Pump Specifications: Flow Rates — Range from 3.9 ml/min to 3000 ml/min, depending on pump configuration, gearmotor speed and stroke length. Max Discharge Pressures — Range from 5 to 50 psi depending on bellows size. Max Fluid Temperature — To 140°F (60°C)Note: Reduce pressure rating by 50% for fluid temperatures over 120°F (49°C). Note: Reduce pressure rating by 50% for fluid temperatures over 120°F (49°C). Viscosity/Slurries — Maximum fluid viscosity is 5,000 centistokes. Poppet valves can handle fine slurries. Duckbill valves are recommended for heavy slurries or fibrous...

Part Selection BELLOWS METERING PUMPS Tubing Connectors Order Notes: One “X” and one “T” code for each bellows module is required. (When ordering tandem pumps, the largest bellows module is nearest the gearmotor.) Example: 13726-014 (11⁄2" x 11⁄2" two tandem standard model) with EPT/EPDM poppet valves and O-rings and 3⁄8" elbow connectors would be ordered as a 13726-014 X-112 T-008 X-112 T-008.

Bellows Pump BELLOWS METERING PUMPS Single Check Valve Check and Foot Valves Opening Pressure: 1 psi (spring loaded) Check and foot valves are used to maintain a pump’s prime or to prevent backflow through a pump in applications with long suction lengths. Check valves can be positioned in-line on the suction or discharge side of the pump; foot valves on the suction side only. To order, refer to the chart on this page. Materials in Contact with Solution: Body, valve seat, connectors, screen (149 Micron) — Polypropylene ® O-rings — EPT/EPDM, Viton®/Fluoroelastomer Spring — Hastelloy® C...

BELLOWS METERING PUMPS – ACCESSORIES Anti-Siphon Spring Kits Anti-siphon springs are available to springload poppet valves. Use of these springs produces more positive shutoff of poppet valves and permits use of the pump where there is a positive pressure on the suction side. Available for the 1", 11⁄2" and 21⁄2" models. To order, select the proper spring material and O-ring by referring to the Chemical Resistance Section. The appropriate kit can then be chosen based on the blow-off pressure (PSI) required.
