IX Series Metering Pumps are digitally controlled direct-drive diaphragm pumps. Years of experience in high-end motor technology result in extremely accurate and energy efficient metering pumps with high resolution. The IX Series meets today’s demand for automated chemical delivery in industries from water treatment to chemical process. Highly precise control offers a solution for a variety of dosing applications. Standard with several control methods, the IX Series pumps provide a solution to a variety of applications all in one pump.

The EJ Series provide precise chemical injection at an economical price. Universal voltage capability enables operation from 100 – 240VAC in virtually all countries. The EJ Series are compact, simple to operate and have outputs to 3.2 GPH (12.0 LPH) and a maximum pressure of 175 PSI (1.2 MPa).

The EWN Series electronic metering pumps offer superior high speed dosing capability with more standard features. The flexibility of the EWN pump enable it be integrated into virtually any chemical feed application using a universal-voltage, digital controller with an expanded set of control features. Superb valve performance and advanced solenoid engineering combine to make a highly precise pump for the most demanding applications.

EZ Series electronic metering pumps offer precise chemical injection at a low cost. The compact size and simple control make them ideal for water treatment and OEM applications.

The EHEis the workhorse of the E-Series metering pumps. EHE Series pumps have outputs up to 20 GPH (75 l/h) and pressure capabilities to 150 PSI (10 bar). Combining the EHE performance with a turndown ratio of 1800:1 yields one of the most versatile pumps in the water treatment industry today. Superior mechanical design and quality manufacturing merge to create a pump better than the sum of its parts. The versatile control features enable the EHE to be integrated into virtually any chemical feed application. The 360 stroke per-minute operation results in high resolution chemical feed and long service life. EHE pumps prime in seconds and hold prime reliably.
