Metering
Features & Benefits
Walchem EHE Chemical Metering Pumps Features & Benefits High Speed Performance E-Series 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-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. 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-Series pumps feature a very high compression ratio that ensures proper feed especially with off-gassing products (i.e. Sodium Hypochlorite).
General Description
All pumps include a manual air vent valve with the exception of FC/HV liquid ends and options P and T. All pumps include one foot valve, one injection valve, 20 feet of polyethylene tubing and one ceramic weight with the exception of HV models (tubing only) and options P and T. Superior mechanical design and quality manufacturing merge to create a pump better than the sum of its parts. The versatile control features enable the EHE to be integrated into virtually any chemical feed application. The 360 strokeper-minute operation results in high resolution chemical feed and long service life. EHE pumps prime in seconds and hold prime reliably. Versatile EHE pumps meet the demands of applications requiring accuracy over a wide output range. The 1800:1 turndown ratio provides the ability to accurately control a high capacity pump to very low outputs, without compromising accuracy. This enables oversize pumps to be installed in applications where output requirements fluctuate, or to accomodate future system growth. Control Microprocessor-based circuitry provides operator adjustment of pump speed and external input settings via 4-button keypad. EHE comes with digital and analog external mode control. The external digital input mode features pulse multiply and divide circuitry that is often used in flow proportional systems, such as with a flow meter contactor. The external analog input mode is a programmable 4-20mA input that provides scalable speed adjustment based on any analog signal. Outputs up to 20 GPH (75 LPH) and pressure up to 150 PSI (10 bar) High speed performance at 360 SPM provides high resolution chemical feed. Dual bearing support ensures proper axial movement to extend the life of the diaphragm Dual check valve assemblies in both suction and discharge fittings guarantees fast priming and reliable perfomance High compression ratio ensures proper feed Microprocessor - based control circuitry Operator adjustment of pump speed and external input settings Pump can be set to divide (accumulate) pulses by a factor of 1 to 999 Programmable 4-20 mA input
