Committed to newproduct development, these productsare innovative and revolutionary. Aperfect example is the EK pump - the firstwaterproof IP67 metering pump in theworld.E-CLASSFeaturing four pump sizes, EZ, EW, EK,and EHE, E-Class pumps are poweredby advanced microprocessor-basedelectronics and superior mechanicaldesign. With capacities up to 20 GPHand a maximum pressure rating of 215PSI the E-Class has a pump that willfit any water treatment, municipal andindustrial wastewater, agriculture, waterconditioning, car wash or any otherchemical feed application. And theentire E-class pump line is backed witha comprehensive 2-year warranty thatcovers the entire pump, including theliquid end and diaphragm.HIGH-SPEED PERFORMANCEE-Class pumps operate at 360 strokesper minute. Most competitive productsoperate at 180 SPM or less, resultingin slug feeding, accelerated diaphragmwear and poor feed control.UAL BEARING SUPPORTAll E-Class pumps features dual bearingsupport. The armature and shaft aresupported with a bearing on each end,which ensures proper axial movement,enabling the E-Class to operate at 360SPM, while extending the life of thediaphragm.SUPERIOR CHECK VALVEPERFORMANCEDual check valve assemblies in bothsuction and discharge fittings featureprecision ball guides and tapered seats.Precise machining and molding of partslimit valve ball travel, ensuring that ballsfully seat and seal with every stroke.This superior check valve design andperformance guarantees fast priming.HIGH COMPRESSION RATIOThe compression ratio of a metering pumpis important because it affects the pumpsability to prime and vent. The compressionratio is raised when you reduce thedead volume of the pump head duringoperation. All E-Class pumps feature avery high compression ratio that ensuresproper feed, especially with off-gassingproducts (i.e. sodium hypochlorite).Pump Series EZ Series Pg 411 EW Series Pg 412 EK Series Pg 413 EHE Series Pg 414 LK Series Pg 415Control Module Digital Timer F Module Y Module R Module E Module Note 1Max Flow (GPH) 6.7 6.7 6.7 20 114Max Pressure (PSI) 150 150 (215) 150 (215) 150 225Strokes per Minute 360 360 360 360 58/ 116Turndown Ratio 360:1 1800:1 1800:1 1800:1 -Stroke Length Adjustment Fixed 20 - 100% 20 - 100% 20 - 100% 10 - 100%IP Rating IP 65 IP 65 IP 67 Waterproof IP 65 IP 65Multi-Function Valve Option B/C10, 15, 20 B/C10, 15, 20 B/C10, 15, 20Degassing Valve Option B10/15 & C15/20 B10/15 & C15/20 B10/15 & C15/20PosiFlow Option B/C10, 15, 20 B/C10, 15, 20 B/C10, 15, 20Pulse Input √ √ √ √Pulse Multiply & Divide √ √4-20 mA Input √ √ *PosiFlow Input√Stop Input √ √ √ √Pre-Stop Input√Pulse Output √ √Stop Output √ √Timer OptionEZB* Standard turndown ratio of the LK is 10:1.
