EZ Metering Pumps Information

Product Type
Metering
Features & Benefits
High Speed Performance - E-Series pumps operate at 360 strokes-per-minute, providing high resolution chemical feed. Most competitive products operate at slower speeds, resulting in slug feeding, accelerated diaphragm wear and poor feed control. 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. 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). Innovative Timer Control - The EZ-Timer module integrates Walchem’s EZB pump technology with a versatile programmable timer. Timed feed control can be programmed in daily or weekly cycles.
General Description
Walchem EZ Chemical Metering Pumps Features & Benefits Outputs to 6.3 GPH and pressure capabilities to 150 PSI. Simple to operate microprocessor control with a turndown ratio of 360:1 EZ-Timer module for timed feed control Can be programmed in daily or weekly cycles. Weekly schedules can be programmed in either 1 or 2-week cycles with a daily on-time. Daily timer can be set for multiple daily on-times. Dual bearing support ensures proper axial movement extending the life of the diaphragm.
