Walchem EZ Series Metering Pumps are simple to operate with only three push-button keys and the turndown ratio provides both versatility and high resolution chemical feed which eliminates slug-feeding effects.

All Walchem 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. 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 check valve design guarantees fast priming and reliable performance. 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.

Walchem E-Series pumps feature a very high compression ratio that ensures proper feed especially with off-gassing products (i.e. Sodium Hypochlorite). The EZ-Timer module integrates Walchem's EZB pump technology with a versatile programmable timer.
