E Series
Domestic hot water pumps
The E Series pumps’ highly efficient ECM (Electronically
Commutated Motor) design results in significant
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
efficiency. 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
market 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 fluid.
• 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 stepless scale protection
thermostats are optional.
Adjustable Thermostat Option
For models with the adjustable thermostat, there is an
adjustable 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 fixed-speed motors.
Energy Efficient Due to ECM Technology
Benefits
• 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 first pump to run off
of 10 watts - about the same
as a night light!
