Compliancy
Panasonic variable speed centrifugal
pumps are designed for circulation of
liquids (hot / cold water and brine
water).
Specific applications include
residential hot / cold water circulation,
and sanitary water supply*4
Panasonic designed and
manufactured DC brushless motors
enable consistent quality, compact
size and customization.
The variable speed capability and
feedback signal of rotation speed
enables sophisticated control and
improved efficiency over the full range
of operation.
Ready for the Ecodesign Requirement
from 2015 with EEI ≤ 0,23
*1: Measured at rated point and 1m away from the pump
*2: The benchmark for the most efficient circulators is EEI ≤ 0,20. Part 3
*3: Custom housing with more water resistance available
*4: The use for the sanitary water supply is depending on the local regulation. Please contact us for detail
