Metering Pumps - E Series From Walchem Corporation

E Series Metering Pumps

Walchem and Iwaki combined their talents to design the most innovative and comprehensive metering pump product line in the world. With over 50 years of combined pump experience, in an array of different markets, the Iwaki-Walchem partnership leverages our strengths to exceed even our toughest customer expectations. Committed to new product development, our products are innovative and revolutionary. A perfect example is the EK pump - the first waterproof IP67 metering pump in the world.

Featuring four great pump series, EZ, EW, EK and EHE, E Series pumps are powered by advanced microprocessor-based electronics and superior mechanical design. With capacities up to 20 GPH and a maximum pressure rating of 215 PSI, the E Series has a pump that will fit any water treatment, municipal and industrial wastewater, agriculture, water conditioning, car wash or any other chemical feed application. And the entire E Series pump line is backed with a comprehensive 2-year warranty that covers the entire pump, including the liquid end and diaphragm.

High Speed Performance
E Series pumps operate at 360 strokes-per-minute. Most competitive products operate at 180 SPM or less resulting in slug feeding, accelerated diaphragm wear and poor feed control.

Dual Bearing Support
All E Series pumps features dual bearing support. The armature and shaft are supported with a bearing on each end, which ensures proper axial movement, enabling the E Series to operate at 360 SPM while extending the life of the diaphragm.

Superior Check Valve Performance
Dual Check Valve Assemblies in both suction and discharge fittings feature precision ball guides and tapered seats. Precise machining and molding of parts limit valve ball travel, ensuring that balls fully seat and seal with every stroke. This superior check valve design and performance guarantees fast priming.

	EZ Series EZ pumps have outputs to 6.3 GPH and pressure capabilities to 150 PSI. The compact size and simple control make it ideal for OEM applications, water treatment, car wash and other industrial applications.			EW Series   The EW Series is the flagship of the E-Class with capacities up to 6.7 GPH (25.4 l/h) and a maximum pressure of 150 PSI (10 bar). Compact, powerful and packed with a variety of innovative design features the EW can enhance any feed application.

	EK Series The EK Series pumps are the world's first IP67 electronic metering pumps. This means that the EK is the only pump in the industry guaranteed to operate submerged 3 feet under water for up to 30 minutes!			EHE Series EHE pumps have outputs up to gallons per hour and pressure capabilities from 30 to 150 PSI. Combining the EHE performance and a turn-down ratio of 1800:1 yields one of the most versatile pumps on the market today.
