Kirchhoff's loop rule (otherwise known as Kirchhoff's voltage law (KVL), Kirchhoff's mesh rule, Kirchhoff's second law, or Kirchhoff's second rule) is a rule pertaining to circuits, and is based on the principle of conservation of energy.
ECM stands for Electronically Commutated Motor. Basically, circulator pumps with ECM motors offer intelligent speed control. Speed-controlled pumps automatically adjust their output to changing demand, whether it be due to outside temperature, level of sunlight, overall activity, and other heating sources. The benefit of having a more efficient ECM motor pump is substantial energy savings, which directly relates to cost savings.
Centrifugal Pump- Definition. â¢ Centrifugal Pump can be defined as a mechanical device used. to transfer liquid of various types. â¢ As the name suggests, it relies on the principal of Centrifugal. force. â¢ It converts the energy provided by a prime mover, such as an. electric motor, steam turbine, or gasoline engine, to energy. within the liquid being pumped.
