8 The Wilden M O T I O N Type: Positive Displacement, Reciprocating, Air-Operated, Double-Diaphragm Pump Major Components: Wetted Components Parts that come into contact with liquid Air Distribution System Air chambers, center block & air valve Elastomers Diaphragms, check valves, valve seats & o-rings Dynamic Components: Two diaphragms are connected to a common shaft and act as a separation membrane between the compressed air and the liquid Two inlet and two discharge check valves open and then close to direct liquid flow The Air Distribution System alternately supplies air to the right and then the left side of the pump A B Figure. Figure.. Air supply is directed to the left air chamber behind diaphragm A. Diaphragm A is driven by compressed air away from the center section and toward the liquid chamber 3. The opposite diaphragm (diaphragm B) is pulled in by the common shaft. Diaphragm B is now on its suction stroke while diaphragm A is on its discharge stroke. The movement of diaphragm B toward the center block opens the bottom right check valve and closes the upper right check valve 6. This movement creates a vacuum within liquid chamber B. Atmospheric pressure forces fluid into the inlet manifold, past the lower right inlet check valve and into liquid chamber B. When the pressurized diaphragm A reaches its full stroke, the air distribution system redirects the air supply to the back side of diaphragm B A Figure. B Figure.. The pressurized air forces diaphragm B away from the center block and the common shaft pulls diaphragm A toward the center section. The air chamber on side A exhausts its air to atmosphere 3. Diaphragm B is now beginning its discharge stroke while diaphragm A is beginning its suction stroke. Diaphragm B creates hydraulic force that begins to close the lower right check valve and opens the upper right check valve. Diaphragm A creates a vacuum that begins to open the inlet check valve (lower left) and closes the discharge check valve (upper left) Figure 3.. As the pump continues to stroke toward the right (toward diaphragm B), side A fills with fluid as side B discharges fluid. When side B reaches its complete stroke, the air distribution system redirects the air supply back to side A 3. When the pump completes two strokes (one on each side) a complete pumping cycle is achieved A B Figure 3.

10 Progressive Diaphragm T E C H N O L O G Y Diaphragm Considerations Flex Life Chemical Resistance Temperature Limitations Abrasion Resistance Initial Cost Traditional Rubber Diaphragms Rubber diaphragms are designed to maximize life, abrasion resistance and chemical compatibility A nylon fabric mesh is positioned within rubber diaphragms during the molding process to strengthen the diaphragm while distributing stress Ultra-Flex Diaphragm Technology Guaranteed longer life - If longer life is not experienced, Wilden will send you a new set of Ultra-Flex diaphragms free of charge. See product flyer for details Convolute shape, altered fabric placement, and unique hardware work together to decrease the unit loading on the diaphragm and distribute stress Thermoplastic Elastomer (TPE) Thermoplastic diaphragms are manufactured by molding proprietary compounds into finished parts Thermoplastic diaphragms are molded without fabric reinforcement due to their inherent tensile strength Thermoplastic diaphragms exhibit excellent abrasion resistance Teflon (PTFE) Teflon is the most chemically inert compound Wilden patented our Teflon diaphragms with concentric ribs to control the flex pattern of the diaphragm to maximize life A back-up diaphragm is used to provide support and lengthen the Teflon diaphragm life Tetra-Flex Technology Gylon PTFE Laminate (one-piece diaphragm) Guaranteed longest-lasting PTFE laminate diaphragm on the market (see product flyer for details) Improves the sealing characteristics of the pump Handles high fluid inlet pressure applications Please verify the chemical resistance capabilities and temperature limitations of elastomers and all other pump components prior to pump installation.

11 Performance D A T A Maximum Flow Rate Determined by pumping water into tanks The flow rate was calculated based on time and weight of water pumped Viscosity and specific gravity of process fluid will affect flow rates Maximum Diameter Solids Maximum solids diameter figure was determined by pumping solids through pump The solids were non-compressible and round in size Geometry of solids and compressibility will affect passage Suction Lift Capability Calibrated for pumps operating at 30 m (000 ft) above sea level The figures listed in this brochure are the maximum lift capable for each specific pump Suction lift capability is affected by many variables including viscosity & specific gravity Consult the Engineering, Operation & Maintenance Manual for complete data Performance Curves Pumps should be specified so that daily operation parameters will fall in the middle of the curve Many curves exist for each pump depending upon elastomeric configuration Consult the Engineering, Operation & Maintenance Manuals for complete data How to Read Performance Curves Determine the flow rate you require and determine your discharge head Plot the intersection of the discharge head on the vertical axis to the flow rate on the horizontal axis (see dot) Locate the blue curve closest to this intersection and follow it to the vertical axis to the left This is the air supply pressure needed to provide the flow rate at the given head Locate the gray curve closest to the intersection and follow it up to where the numbers are provided This number is the air supply volume needed to provide the flow rate you require at the given head Discharge Head BAR FEET PSIG Water Flow Rates GPM [LPM] (0) [] 0 [3] (0) [3] (30) [] () [6] (0) [] () [0] 0 [6] 30 [] [] 0 AIR INLET 00 PRESSURE (psig) 0 0 [9] [] 0 [6] [303] 90 [3] Example: To pump 63 lpm ( gpm) against a discharge pressure head of. bar ( psig) requires. bar ( psig) and 3 Nm 3 /h (0 scfm) air consumption (see dot on chart).

41 ACCU-PULSE T E C H N O L O G Y Peristaltic dosing pump Precise dosing and metering Chemical injection Ability to pump two chemicals with one pump The Technology Peristalsis occurs when the rotation of the rollers around the inside diameter of the tube housing compresses and dilates that pumping tube. Its motor turns its shaft at a constant RPM (6 or ). The feed rate controller establishes the rotation of the pump roller assembly The feed rate is set manually via the dial ring. The motor rotates the pump roller assembly, which compresses the tube to the pump housing. Fluid is captured in the tube between rollers and is displaced as the rollers rotate.
