Welko WLK 32-12 Variable-Speed Circulation Pump, Chrome, Stainless Steel Casing

Welko WLK 32-12 Chrome Variable-Speed Circulation Pump

Designed for those seeking high efficiency and long service life in heating, cooling, and especially domestic hot water (hot water cylinder) systems, the Welko WLK 32-12 Chrome is equipped with advanced variable frequency drive technology.

Unlike standard cast iron casing pumps, its stainless steel (chrome) casing makes this pump extremely resistant to corrosion and rust. As a result, it operates safely on drinking water and hot water cylinder circulation lines without compromising water hygiene.

It detects the instantaneous pressure and flow rate demand of the system and automatically adjusts the motor speed. Instead of running at full capacity when the system does not require it, it reduces speed to achieve significant energy savings and eliminates unnecessary circulation noise (humming) in the pipework. It is a direct performance equivalent of the well-known DAB EVO PLUS 110/180 XM model and is offered at a much more accessible price.

What Are the Application Areas?

Thanks to its stainless steel construction and variable frequency drive, it has a very wide range of applications:

• Domestic Hot Water (Hot Water Cylinder) Lines: Its stainless steel casing does not degrade water quality and does not oxidize over time. (The most common application area.)

• Underfloor Heating Systems: Detects resistance in the pipes and adjusts speed to provide quiet and balanced heat distribution.

• Central Heating and Central Heating Systems

• Solar Heating Systems

• Air Conditioning and Cooling Systems

• Industrial Washing and Hot Water Applications

Why Should You Choose This Pump?

Older-style pumps that continuously run at the same speed (3-speed) cause significant electricity consumption. The Welko WLK 32-12 Chrome, with its next-generation motor design, pays back the investment cost in a short time through electricity savings. In addition, thanks to its standard 180 mm installation length, it can be easily swapped in place of your existing pump without any pipe modifications.
