Replace pumps quickly and efficiently

When it comes to maintenance or the perfect pump replacement, you can choose from the DERBLAUE® range as needed: In some situations, the tub is the best option. In more complex situations, funnels, rosettes and chutes can be combined to ensure safe drainage without splashes. The funnels, available in two different sizes, have a 3/4 inch brass connection. Simply attach a hose and direct the water directly into the drain.

Maintenance of a wall heater

The tub is positioned below the burner chamber so that the burner chamber can be rinsed and cleaned. If necessary, the water can be directed into the tub via the slide. The powerful pump, operated with a splash-proof battery or power pack, pumps the water away at 10 liters / min.

Maintenance of the heat exchanger

When cleaning the heat exchangers, the regulators must be adjusted. It is also particularly important to clean the condensate drains, as these can become blocked. This is where the drip tray comes in, which can be perfectly mounted under any condensate drain. The flexible bending metal elements can be shaped as often as you like and then remain stable. Helpers such as slides or rosettes can also be used here to protect against splashes and to guide the liquids ideally.
