Description
The Walchem EWP Series Metering Pump has flow rates up to 6.7 gph and pressure capabilities up to 300 psi within a compact housing rated to IP66. The footprint is designed for easy installation or OEM integration. It operates at 360 strokes per minute, providing a high resolution chemical feed.
The EWP Series' high compression ratio ensures proper feed especially with off-gassing products (i.e. Sodium Hypochlorite). The armature and shaft are supported with a bearing on each end, ensuring proper axial movement, enabling the E-Series to operate at 360 SPM while extending the life of the diaphragm and mechanics.
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. The superior check valve design guarantees fast priming and reliable performance.
