E SERIES

With four major pump series, EZ, EWN, EHE, and EJ, the E-series metering pumps are powered by advanced microprocessor-based electronics and superior mechanical design. With capacities up to 20 GPH (76 l / hr) and pressures up to 290 psi (20 bar), the E Series has a pump to suit most industrial, municipal or agricultural wastewater or applications. The entire line of E-Series pumps is backed by a comprehensive warranty that covers the entire pump, including wetted parts and diaphragm.

Benefits: NSF Std 50 and 61 certifications, 2-year warranty, 360 pulses per minute, 1-to-1 regulation, and resolution up to 1800: 1

EWN

The EWN series electronic metering pumps offer superior high-speed metering capacity with more standard features. The flexibility of the EWN pump allows it to be integrated into virtually any chemical feed application using a universal voltage digital controller with an expanded set of control features. Excellent valve performance and advanced solenoid engineering combine to make a high precision pump for the most demanding applications.

EHE

The EHE is the workhorse of the E-series metering pumps. The EHE-series pumps have outputs up to 20 GPH (75 l / h) and pressure capabilities up to 150 psi (10 bar). Combining EHE performance with an 1800: 1 gear ratio produces one of the most versatile pumps in the water treatment industry today.

Benefits: IP65 construction, waterproof, 360 pulses per minute, 1 to 1 dimming, resolution up to 1800: 1, digital mode control & 4-20 mA

EZ

The 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.

Benefits:  Economical series, 360 pulses per minute, 1 to 1 regulation, modular

Ej

The EJ series provides precise chemical injection at an economical price. Universal voltage capability allows 100 to 240 VAC operation in virtually all countries. The EJ series is compact and simple to operate. It has 3.2 GPH (12 LPH) outlets and a maximum pressure of 175 PSI (1.2 MPa).

Benefits: Economical series, 360 pulses per minute, 1 to 1 regulation, digital input, on/off input

SERIES IX

The IX series is Walchem’s most powerful range. They are digitally controlled direct-drive diaphragm metering pumps. Years of experience in high-end motor technology result in extremely precise and energy-efficient metering pumps with high resolution, capable of meeting today’s demands for automatic chemical dosing in industries such as water treatment or chemical processes. They feature highly precise controls and offer the ultimate solution for a variety of dispensing applications.

Benefits: High compression ratio, high precision, energy saving, head with efficient design, diaphragm rupture sensor

IX-b

With all the accessories in the series, the IX-B exceeds the characteristics of any pump in the same flow range. It can be controlled both manually and automatically through digital, analog signals, or even with Profibus communication.

Benefits:  Flow rates up to 45 liters per hour, discharge pressure up to 145 psi, all the benefits of the IX series, with rotating screen and adjustable in 4 positions, adjustable base to place wall anchored, degree of protection IP65

IX-c

A pump that exceeds energy consumption expectations thanks to the Brushless motor. This pump has been applied in different industrial sectors with guaranteed success. It has replaced pumps of other technologies, thanks to the long life of its diaphragm that reduces operating costs and maintenance stops.

Benefits: Flow rates up to 150 liters per hour, discharge pressure up to 145 psi, all the benefits of the IX series, display available in 6 positions, LCD screen with LED backlight, LED indicators for pump status

IX-d

It has the highest capacity of Walchem pumps. A robust pump ready to meet the most demanding processes with high precision. Easy to automate and operate, it features a diaphragm rupture sensor just like the other pumps in the series.

Benefits: Flow rates up to 300 liters per hour, discharge pressure up to 145 psi, all the benefits of the IX series, display available in 6 positions, LCD screen with LED backlight, LED indicators for pump status
