Water Treatment Chemical Pump - Ideal for Water Treatment

EZ Series Water Treatment Chemical Pump offer precise chemical feed injection at a low cost. The compact size and simple control make them ideal for water treatment and OEM applications.

• Low-Cost High Performance Pump
• Up to 360 spm High Resolution Feed
• Digital Display and 4-Button Keypad
• Flow Rates up to to 6.3 GPH
• Pressures up to 150 psi
• Timer Control Module Option

EZ 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.

Water Treatment Chemical Pump

• 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 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 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).
• 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.

EZ Water Treatment Chemical Pumps have outputs to 6.3 GPH (24 l/h) and pressure capabilites to 150 PSI (10 bar). The compact size and simple control make it ideal for OEM applications.

Effective, reliable performance is achieved through sophisticated engineering. Designed with a turndown ratio of 360:1, the EZ is an exceptional value.

Simply stated – the EZ packs all of the 360spm performance of the bigger pumps into the compact chassis of the industry’s easiest pump to operate. The EZ is the best on/off pump on the market. Built to prime, hold prime and to last, the EZ Series metering pump offers precise chemical injection at an economical cost.

Features include double ball check valves, long lasting diaphragm, an optional automatic air vent valve and the ability to remotely mount the control unit.
