46:. The ECM is a motor that converts a direct current (DC) from an electrical source into an alternating current (AC) which is sent to the motor itself, allowing for increased efficiency over standard AC motors. The permanent magnet rotor consists of an iron core, surrounded by multiple magnetic rare earth metals, and finally a metal sleeve that evenly spaces the magnets around the core, which helps to drive the motor. By utilizing multiple small improvements in pump-design technology such as a double pump in parallel system and variable controls, these pumps are able to run at about a 50% to 70% increased efficiency with up to an 80% decrease in electricity consumption over the previous standard design. This pump has recently become the new standard in both commercial and residential buildings across the

increasing efficiency and reliability. Using the pump's variable controls allows the pump to base its amount of energy consumption on how much it is actually performing, cutting down on usage during non-peak hours and extending the pump's life span. The automatic controls allow the pump to follow a set schedule of how much energy to consume during specific hours, which allows building owners to cut down even further on electricity costs. By dividing the output into a double pump in parallel design, the system is able to greatly adapt to partial load conditions. This accounts for a significant increase in reliability and the 50% to 70% efficiency increase that these high efficiency pumps achieve.

unique design. Whereas standard pumps with shaft seals have multiple chambers with different rotating parts in each, canned rotor technology allows all of the rotating parts within the pump to exist in a single chamber. This increases the overall efficiency since the liquid used to lubricate the shaft bearings is also used to cool the motor. The electronic components of the motor are attached outside this system by means of an encapsulated motor cartridge, which is an independent metal compartment used solely for housing the electronic components.

design key to an increase in efficiency and decrease in energy consumption. Although the pump can be installed both inside and outside of buildings, many precautions must be taken in order to protect the pump from unfavorable weather conditions. These pumps are fairly simple to integrate into systems that follow the old standard since each pump is able to increase its efficiency by changing its design internally, meaning it will still fit into older systems without any problems requiring special adapters.

Many minor factors of the pump's design including its double pump system and control options give it additional efficiency without sacrificing any of its performance. By using a double pump system together with variable and automatic control, the pump is able to decrease its energy consumption while

The primary design factors of a high efficiency glandless circulating pump include an electronically commutated synchronous motor, a permanent magnet rotor, and canned rotor technology. An electronically commutated synchronous motor is used to convert the energy current from a DC energy source into

which is generated by surface currents placed on the surfaces of the stator and rotor and the permanent magnets to generate the electric current which is in output to the drive motor. The canned rotor technology eliminates the need for a shaft seal that many conventional pumps must use through its

These types of pumps are used primarily in heating and air conditioning systems within both residential and commercial buildings such as offices and apartment complexes. The pump is the central component of these systems and accounts for most of the electricity usage within the system, making its
