Circulation pumps

Selection is based on two primary parameters: Head (the ability to overcome system resistance) and Flow Rate (the volume of coolant moved per hour). EKVIVES experts recommend calculating the duty point based on the total boiler capacity and the length of the heating circuits for maximum efficiency.

In Wet Rotor pumps, the pumped liquid lubricates the bearings and cools the motor, ensuring near-silent operation (ideal for residential use). Dry Rotor pumps have higher efficiency and are designed for large-scale industrial systems or district heating, though they require regular mechanical seal maintenance.

Yes, most modern EKVIVES circulation pumps are universal. They are designed to operate across a wide temperature range, making them suitable for both heating systems and cooling/air conditioning (HVAC) loops.

Pumps with frequency control automatically adapt their speed to the system's current demand. This can reduce energy consumption by up to 50-70%, eliminate hydraulic noise in thermostatic valves, and significantly extend the service life of the pump.
