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.
EZ Series have outputs to 6.3 GPH (24 l/h) and a maximum pressure of 150 PSI ( 10 bar). Advanced microprocessor control and a turndown ratio of 360:1 make this series an exceptional value. The pumps are simple to operate with only three pushbutton keys and the unmatched turndown ratio provides both versatility and high resolution chemical feed which eliminates slug-feeding effects.

 

 

EW Series electronic metering pumps offer superior dosing capability. The versatile control features enable the EW to be integrated into virtually any chemical feed application. Superb valve performance and advanced solenoid engineering combine to make a highly precise pump for the most demanding applications.
EW pumps have outputs to 6.7 GPH (25.2 l/h) and a maximum pressure of 250 PSI (17 bar). The high speed of operation results in high resolution chemical feed and long service life. Quiet and compact, EW pumps prime in seconds and hold prime reliably.

 

 

Electromagnetic metering pumps with various
controls and abnormality detections
Conventional electromagnetic metering pumps generally suffer from low resistance to exposure of external liquids.
With improved sealing of not only the control unit but also the pump unit, a remarkable improvement to this exposure has been achieved in the EW series.
With its tough construction and high tolerance to external liquids, the EW series can be widely used in applications ranging from incorporation into various devices to utilization as standard equipment in water treatment facilities.

 

 

The EHE is the workhorse of the E-Class 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 of 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.

 

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.
