Thermal insulation (1)
Thermal insulation shell
Thermal insulation shell	Thermal insulation shell	4206066
Thermal insulation shell	Appropriate thermal insulation shell for on-site thermal insulation of the pump housing for heating applications. Suitable for screwed-version single pumps with an installation length of 130 mm and 180 mm. Reduces the heat losses of the pump by up to 85 % Ensures an even temperature distribution at the pump Reduces the overall energy consumption of the heating system and saves energy costs. Groundwater neutral, propellant-free, formaldehyde-free and 100 % recyclable. Processing notes With on-site thermal insulation, the pump housing can only be isolated up to the separating gap to the motor (not the motor), the condensate drainage outlets must not be covered! Scope of delivery Two-piece thermal insulation shell
