结构

Glanded double pump in in-line design with flange connection

应用

For pumping heating water (in accordance with VDI 2035), water-glycol mixtures and cooling and cold water without abrasive substances in heating, cold water and cooling water systems

特点/产品优势

• High-efficiency motors as standard; from 0.75 kW nominal motor power: motors with IE2 technology
• Reduced life cycle costs due to optimised efficiency
• Standard condensate drainage holes in the motor housings
• Can be used flexibly in air-conditioning and cooling systems, with application benefits due to direct draining of condensate via optimised lantern design (patented)
• High corrosion protection thanks to cataphoretic coating
• Bidirectional mechanical seal with forced flushing
• High worldwide availability of standard motors (according to Wilo specifications) and standard mechanical seals
• Reduction of space required and installation costs due to double pump design
• Main/standby mode or peak-load operation (by means of external auxiliary device)
• Peak-load operation (by means of external auxiliary device)
