E Series
Domestic hot water pumps
The E Series pumps’ highly efcient ECM (Electronically
Commutated Motor) design results in signicant
energy savings with improved performance. Through
microprocessor technology the motor is provided the
precise frequency and voltage for optimum performance.
A permanent magnet motor eliminates the requirement
for input power to magnetize the rotor, thus maximizing
efciency. This unique design offers superior starting
torque when compared with standard induction motor
type pumps.
The spherical motor design:
The only moving part of this pump type is a spherical
rotor/impeller unit which is suspended on an extremely
wear resistant ceramic ball. Shaft seals or conventional
bearing bushings with a shaft have been eliminated.
The only self realigning bearing in the small pump mar-
ket has many advantages:
• The suspension on a ball eliminates any bearing play,
even after years of use.
• The bearing is self-realigning. It is automatically
lubricated and cooled by the system uid.
• The rotor is magnetically centered on the bearing
and therefore can tilt to avoid blockage by small dirt
particles. Even after a long time of shut-off, a safe
start-up is virtually guaranteed.
• The pump can be cleaned easily with typical
household cleaners in the unlikely case of scale
deposits. Integrated step-less scale protection
thermostats are optional.
Adjustable Thermostat Option
For models with the adjustable thermostat, there is an ad-
justable Set Point range from 68
º
F to 158
º
F (20
º
C to 70
º
C).
This built-in temperature sensor will turn the circulator off
when it reaches the Set Point and turn the circulator on
when the temperature is more than 10
º
F (6
º
C) below the
Set Point. The adjustable thermostat is only available on
xed-speed motors.
Energy Efcient Due to ECM Technology
Benets
• Instant availability of hot water, even at the tap
farthest from the hot water heater.
• Conserves natural resources - reduced power
consumption, CO
2
emissions and wasted water.
Features
• Easy installation
• Programmable timer and built-in thermostat available
to further reduce energy consumption.
• Available with integrated check and ball valves for
quick isolation during service.
The rst pump to run off
of 10 watts - about the same
as a night light!
