Wilo Pump PARA ST15-130/7-50/PWM2

Due to new European ERP Directives, all pumps must now be of the high efficiency type, for solar thermal, this means advanced speed control must be applied, for this reason, our new replacements for standard pumps are the ones below.

Design:
Glandless circulation pump with a cast iron pump housing and threaded. EC-motor with automatic power adjustment and self-protecting modes. Operation via external PWM signal.
Mechanical design dedicated to solar thermal applications.
This pump can only be controlled via a suitable controller with PWM/0-10v control. If your controller only has standard triac speed control, you will need to add a Resol Basic PSW signal converter. (related Edit Products below)

Application:
Circulation in solar thermal systems in the medium temperature range of -10 °C to +110 °C with short peaks of 140 °C.

Special features / Edit Product benefits:
Externally controlled via a PWM signal
Self-protecting modes
Designed for optimised integration
130mm Spacing
1 Male Connection
