EK Series | Metering Pumps
OVERVIEW
The EK Series pump is the world’s first IP67 electronic
metering pump and is the only pump in the industry
guaranteed to operate submerged 3 feet under water for
up to 30 minutes! This makes the EK Series pumps ideal
for wet or high humidity environments such as irrigation,
agriculture, food & beverage, car wash or paper mill
applications.
The EK Series are highly precise metering pumps with
outputs to 6.7 GPH (25.2 l/h) and a maximum pressure
of 150 PSI (10 bar). The 360 stroke-per-minute operation
results in high-resolution chemical feed and long service
life. Quiet and compact, EK pumps prime in seconds and
hold prime reliably.
SUMMARY OF KEY BENEFITS
High Speed Performance
E-Class pumps operate at 360 strokes-per-minute. Most competitive products operate at 180 SPM
or less resulting in slug feeding, accelerated diaphragm wear and poor feed control.
Dual Bearing Support
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 and performance guarantees
fast priming.
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).
