Circulation pump Wilo-Yonos MAXO 65/0.5-16 PN6/10
Circulation pump Wilo-STAR-Z 20/5-3(150mm) 4081198
The Wilo-STAR-Z 20/5-3(150mm) circulating pump is a top-performance device designed for efficient heat distribution in heating, air-conditioning, closed-loop cooling and industrial circulating systems. With a built-in length of 150 mm, the pump is extremely versatile and easy to install, and its standard built-in fault contact and LED display allow quick monitoring of the set head
The unit allows smooth adjustment of performance by selecting one of two operating characteristics: constant-pressure (p-c) or variable-pressure (p-v) mode. In addition, the pump offers 3 operating modes, minimum power consumption of 5 W (EEI 0.2) and integrated full motor protection, resulting in high energy efficiency and reliability
Thanks to the 1:1 dimensional interchangeability with old standard pumps and the simplicity of parameter setting via Wilo's red knob, installation and operation of the unit is extremely intuitive. Cataphoresis (KTL) coating on the body protects the pump from corrosion due to condensation
