[5] The canned rotor technology eliminates the need for a shaft seal that many conventional pumps must use through its unique design.
By dividing the output into a double pump in parallel design, the system is able to greatly adapt to partial load conditions.
[3] 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.
High efficiency glandless circulating pumps have become the industry standard when developing and maintaining buildings within the European Union due to recent changes to the carbon emissions goals.
Various companies such as Wilo have successfully developed pumps that have been projected to save up to 80% in electricity usage, meeting both of the new grading scale minimums set this year and in 2015.
[7] Pump designs are still being revised to continually try to achieve higher efficiency standards and lower the impact on the environment in order to meet the goal of up to a 50% reduction in both CO2 emissions and electricity usage across the EU by 2020.
