New walchem iwaki metering pump 3.2 gph EZB30D1-tc box
NEW, IN THE ORIGINAL WALCHEM BOX, IWAKI METERING PUMP EZB30D1-TC.
EZ SERIES ELECTRONIC METERING PUMP COMES WITH INSTALLATION SET AND INSTRUCTION MANUAL..
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
All E-Class 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-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
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).
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.
