Walchem and Iwaki have over 100 years of combined metering pump experience. This partnership has resulted in the development of the world’s most advanced line of chemical metering pumps, the EClass. Featuring 5 great pump series, E-Class and LKN pumps are powered by advanced microprocessor electronics and superior mechanical design.

EK Series Pumps are the world’s first electronic metering pumps with an IP67 rating (able to operate submerged under 3 ft. of water for up to 30 minutes).
The workhorse of the E-Class - no other electronic metering pump can match the power and performance of Walchem's 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. Superior mechanical design and quality of manufacturing merge to create a pump better than the sum of its parts. The EHE Series is ideal for chemical feed applications in a wide range of fields, including water treatment, chemical process, municipal and industrial wastewater. Powerful The EHE35 size pump is the most powerful electronic metering pump currently available. A pump's maximum pressure rating times its maximum output at that pressure gives a relative measure of the pump's hydraulic output power, a "power index". Control Microprocessor-based circuitry provides the operator adjustment of pump speed and external input settings via a 4-button keypad. The EHE comes with digital and analog external mode control.
The LK Series metering pump is the largest in the high performance line of pumps from Walchem Corporation. The LK is a motor-driven, mechanically actuated diaphragm metering pump with a maximum capacity of 114 GPH (432 l/h) and a maximum pressure of 225 PSI (1.5 MPa). The heart of the LK is a compact and very reliable dual-cam system drive and worm gear reducer. Roller bearings and oil bath lubrication ensure outstanding durability and wear resistance in continuous operation. The LK Series is ideal for chemical feed applications in a wide range of fields, including water treatment, chemical process, agriculture, mining and paper.
