Walchem EZB21D1-VC Series Electronic Chemical Metering Pump, 1.5 GPH, 60 psi


$ 428.00

Walchem EZB21D1-VC 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.

Walchem Chemical Metering Pump EZB21D1-VC 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.

High Speed Performance E-Class 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-Class pumps feature dual bearing support. The armature and shaft are supported with a bear- ing on each end, which ensures proper axial movement, enabling the E-Class 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-Class pumps feature a very high compression ratio that ensures proper feed especially with off-gassing products (i.e. Sodium Hypochlorite).   Optional 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.
