Xylem Lowara 10 bar Solar Central Heating Pump, 2.7m Head, 1/2 in BSP

The first highly efficient long life silent DC spherical motor pump with magnetically coupled impeller for direct connection to photovoltaic panels. This pump is capable of self performance optimisation using MPP (Maximum Power Point) tracking. Every three seconds the pump control processor will modify its operating point on the voltage / current curve of the PV panel at any given insolation. The point of maximum motor performance can then be found and utilised. This pump can be used wherever there is no direct connection to AC power and is ideal for circulating water through solar thermal installations.

Soft start at very low insolation (less than 1 Watt required)
Unique electronically commutated spherical motor with ultra hard wear resistant ceramic ball bearing
Permanent magnet rotor / impeller
Economical and powerful
Long life, blockage free and maintenance free
RF suppressed
Reverse polarity protected
Acceptable media: domesitc hot water, heating water, water / glycol mixtures
