LK
Series Metering Pump
The LK Series Metering Pump is the latest addition to
the high performance line of pumps from Walchem. The LK
is a motor-driven, mechanically actuated diaphragm metering
pump with a maximum capacity of 114GPH (432 l/h) and a
maximum pressure of 225 PSI (1.5 MPa).
The LK Series Metering
Pump is ideal for chemical feed applications in a wide
range of fields, including water treatment, chemical
process, agriculture, mining and paper.

EHE
Series Metering Pumps
The EHE Series is the
workhorse of the EH Family. No other electronic metering
pump can match the power and performance of our EHE.
Powered by 360 SPM advanced electronics, the EHE features
superior mechanical design and quality.

EHB/C
Pumps
The same superior design and advanced features found in
the EHE can be found in the smaller EHB/C pumps. Unique
modular design features two different control options.
The Y module features digital speed control
(1-360spm) with pulse input (multiplier/divider) and a
programmable 4-20mA input. The economical R Module features
speed control, digital pulse input and external start/stop.

EZ
Series Metering Pumps
Simply stated, the Walchem EZ Series Metering Pumps packs
all of the same 360 spm technology of its bigger siblings
into the industry's easiest pump to operate. The Walchem
EZ Series Metering Pumps are the best on/off pump on the
market. Built to prime, hold prime and to last... the
Walchem EZ Series Metering Pumps offers precise chemical
injection at an economical cost.

EH-HV
Metering Pump Series
The EH-HV Series is specifically designed to accurately
feed high viscosity chemicals. Equipped with rugged, machined
PVC liquid ends and spring loaded stainless steel valve
balls, the HV series is designed for superior valve action
and performance. Rated to 20,000 cps*, the HV Series is
available in four feed ranges from 1 to 4 GPH (at 50 PSI).

EH
Series High Compression Metering Pump
Designed specifically for
bleach applications. Self-primes
and more importantly, holds prime. Features
a high compression head with an auto air vent valve ensuring
that bleach-off gassing does not effect pump performance.
We guarantee performance
by offering a 2 year warranty that includes the liquid
end and diaphragm!

EZBT
Timer Metering Pumps
The EZBT Timer Metering Pumps include all of the features
of the EZ pumps plus a programmable timer.
Select the daily mode with 8 events per day, or the 7-day
and 14-day modes with 1 event per day. With 360 strokes
per minute technology and precision double check valves,
the EZBT Timer Metering Pumps are built to prime, hold
prime and to last. There's no better value on the
market. |
| Priming
Capability |
The
EH pump can self prime in seconds, with no action other
than turning the pump on. This is achieved by superior
valve design in conjunction with a uniquely engineered
solenoid drive. |
Superior
Valve
Construction |
The
tightly guided double ball check valves ensure a tight
seal after each pulse, preventing loss of prime. A modular
design enables change-out without having to replace the
entire liquid end. |
Unique
Solenoid &
Armature System |
The
solenoid and pump housing are molded together (except
EHE), making a structurally sound module which will last
the life of the pump. The armature is supported at both
ends, maximizing stability and greatly increasing the
bearing life. The pump drive is able to pulse up to 360
strokes per minute |
| Fast,
Accurate Metering |
360
SPM is a significant advantage in automatic control
situations. The in-line addition of chemical is more uniform,
eliminating slug-feed effects. This is high resolution
chemical feed; more precise, more repeatable. |
| Automated
Operation |
Capability
for automatic control is standard in most of the EH pump
series. The pumps are instrument friendly - able to easily
interface with many controllers and peripherals. |
| Compact
Size |
So
small and lightweight, the EH is ideal for OEM applications
and can readily fit into established installations. The
small size of the pump and its parts actually increases
the length of pump life, as the loads and forces are minimal. |
| Easy
To Install |
The
modular design and small size make EH easy to install. |
