Outputper StrokemlFEATURES• All standard EW Series pumpsfeature: digital display, dual checkvalves, dual bearing support, and ahigh compression ratio.• 360 strokes per minute capacityprovides precise feed accuracy.• Pulse output - capable of sending a pulsesynchronous with pump operation.• Stop input/ output - stop input contactwill stop pump and close stop outputcontact for alarm or remote signal.Red light indicates stop.• Pre-stop input - Orange light giveswarning.• PVC, GFPP, PVDF or 316 StainlessSteel available.• IP67 construction enclosure withclear cover.• Injection capacities to 6.7 GPH.• Injection pressures to 150 PSI.• Approvals: UL and C-UL.ADDITIONAL FEATURES OF PUMPSEQUIPPED WITH Y-MODULE• Analog input control - fixed speedor scalable 4-20 mA input control.ABOUT THE EW SERIESThe EW Series includes a two-level stopfunction for low and empty drum level indicationand an external control functionfor proportional control. The membraneswitches and stroke control of the pumpare mounted opposite the liquid end, undera protective, clear cover. The displayutilizes a high temperature LCD that providesextra protection from sunlight in outdoorapplications. The high compressionratio of the EW’s liquid end combined with• Pulse input control - pulse input withmultiply and divide features (1-9,999).• Keypad lockout for security.• Easy draw-down calibration.• 12 VDC output power supply for halleffect water meters.APPLICATIONS• Water treatment.• Industrial wastewater.• Municipal.• Agricultural.• Metal/ surface finishing.• Food & beverage.• Boilers/ chilled water.• Chemical feed.• Water chemical injection.• Water conditioning.ACCESSORY ITEMS• PosiFlow feed verification sensor.• Chemical storage tanks.• Multifunction valve.• Web alert remote monitoring anddatalogging.• Spare parts kit.SUBSTITUTE ITEMS• Iwaki EHE Series metering pumps.the double check valves result in the abilityto prime quickly and maintain prime.The EW Series are solenoid-driven, diaphragmmetering pumps with capacitiesup to 6.7 GPH (25.4 l/h) and a maximumpressure of 150 PSI (10 bar). At 360strokes per minute, the EW Series providesan outstanding 1800:1 turndown ratioand will reduce the slug feeding foundin most competitive pumps.CONTROL MODULE OPTIONY = For use on all EW models, features analog input, digital input with multiplyand divide, PosiFlow input and alarm options.Max.Pressure*PSI6094.(Size No.) PVDF/VITON, 115 VAC, 50/60 Hz6095.(Size No.) PVC/VITON, 115 VAC, 50/60 Hz6097.(Size No.) PVC/EPDM, 115 VAC, 50/60 HzMax.Pressure*MpaConnectionSize (in.)Tubing O.D.6091 6092 6093 6094 6095 6097SizeNo.038 B10 0.6 38 0.11 150 1.0 3/8 $ 625.00 $ 450.00 $ 450.00 $ 582.00 $ 450.00 $ 450.00039 B10 0.6 38 0.11 150 1.0 3/8 811.00 636.00 636.00 768.00 636.00 636.00065 B15 1.0 65 0.18 105 0.7 3/8 652.00 477.00 477.00 609.00 477.00 477.00066 B15 1.0 65 0.18 105 0.7 3/8 838.00 663.00 663.00 795.00 663.00 663.00096 B20 1.5 115 0.26 60 0.4 3/8 678.00 503.00 503.00 636.00 503.00 503.00097 B20 1.5 115 0.26 60 0.4 3/8 863.00 688.00 668.00 821.00 688.00 688.00200 B30 3.2 210 0.56 30 0.2 1/2 751.00 529.00 529.00 710.00 529.00 529.00080 C15 1.3 80 0.22 150 1.0 3/8 805.00 630.00 630.00 762.00 630.00 630.00081 C15 1.3 80 0.22 150 1.0 3/8 991.00 816.00 816.00 948.00 816.00 816.00130 C20 2.0 145 0.36 105 0.7 3/8 832.00 657.00 657.00 790.00 657.00 657.00270 C30 4.3 270 0.75 50 0.35 1/2 898.00 683.00 683.00 857.00 683.00 683.00420 C35** 6.7 420 1.17 30 0.2 1/2 967.00 710.00 710.00 925.00 710.00 710.00421 C35** 6.7 420 1.17 30 0.2 1/2 1153.00 895.00 895.00 1111.00 895.00 895.00* Auto air vent valve reduces maximum pressure approx. 35 PSI (0.2 MPa).** Output of the EWC35-TC/FC/SH is 6.3 GPH (400 ml/min). 590.110.150 EWB 590.110.160 EWC®412
