6.1 Pump description

Pump (Fig 1)
The circulating pump is fitted with a wet (canned rotor)
motor.
The circulating water service pump Stratos ECO-Z 25/1-5 is
specially designed for use in conjunction with domestic/
drinking water service systems. It is by material selection and
design, corrosion proofed against any residual, parts in
domestic/drinking water.
For thermal insulation the pump housing is lagged with an
insulation shell.
The motor housing is with an electronic control modul
(Item 1) capable of maintaining the pump generated differ-
ential pressure constant at a preset value between 1 and 3 m,
or 1 and 5 m. Pump capacity is thus matched to the changing
load demand which is particularly significant when using
thermostatic control valves.
The essential advantages and benefits are:
• no bypass relief valves required,
• power savings,
• reduction of flow noise.
