Features & Benefits
Walchem EWN Chemical Metering Pumps Features & Benefits High Speed Performance - E-Series pumps operate up to 360 strokes-per-minute with adjustments in 1 spm increments, providing high resolution chemical feed. Adjustable stroke length further increases the ability to refine the output, making the E-Series one of the most versatile solenoid metering pumps on the market. Multi-function Digital Controller - The controller in the EWN-R pump provides for flexible pump control including scalable Analog control, Digital Input with both Multiply and Divide capability, external stop control, or simple speed and stroke length control. Display can be adjusted between flow rate units or % speed for easy-to-read output and quick adjustment. The controller is universal voltage so it can be used anywhere in the world. Engineered Longevity - All E-Series pumps feature 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 guarantees fast priming and reliable performance. Flexible Connections - A removable tubing insert provides flexibility of tubing sizes and eliminates twisting of the tubing during connection. A threaded insert can be used in place of the tubing adapter to easily convert any connection to NPT. High Compression Ratio - The compression ratio of a metering pump is important because it affects the pump’s ability to prime and vent. The compression ratio is raised when you reduce the dead volume of the pump head during operation. All E-Series pumps feature a very high compression ratio that ensures proper feed especially with off-gassing products (i.e. Sodium Hypochlorite).
General Description
The new EWN-Y electromagnetic pump combined with EFS flow sensor provides accurate real-time control and display of dosing rate. Presence of non-conductive media (i.e. oil) in the flow may generate erroneous readings. Set point control allows the desired flow rate to be simply programmed into the pump. Through feedback from the EFS sensor, the pump constantly adjusts its speed to maintain the set dosing rate - even under changing temperature, viscosity or suction and discharge pressure conditions. The EWN-Y provides a clear display of actual dosing rate and a 4-20 mA output signal proportional to the flow rate. An optional Auto Degassing Valve (ADV) can be mounted in-line with the EFS sensor to eliminate gaslock conditions quickly with continuous venting. The EWN-Y pump automatically recognizes the EFS sensor when connected and powered. A standard injection check valve is required when discharge-line length is less than 10 feet. An in-line check valve (purchased separately) is required when discharge-line length is over 10 feet.
