Glandless Pumps (General)
Sound pressure level
The construction of the glandless pumps is the reason for their lownoise
operation. Its air-borne noise values with measuring-surface
sound pressure level Lp (A) [dB] depend on the motor power output
and are determined under normal operating conditions.

Heat insulation with heating applications
All Wilo-Stratos/Stratos-Z, Wilo-TOP-E/-S/-Z/-D and Stratos ECO
single-head pumps are standard-equipped with thermal insulation
shells for the prevention of thermal losses at the pump housing.
Material: EPP, polypropylene foam
Thermal conductivity: 0.04 W/m K in accordance with DIN 52612
Flammability: Class B2 in accordance with DIN 4102; FMVSS 302
When insulating the pump on-site, care must be taken to cover the
pump up to the top edge of the pump housing only (the motor must
be left uncovered).
Thermal insulation for air-conditioning/cooling applications
If pumps from the following series:
- Stratos, Stratos-D, Stratos-Z
-TOP-S/-SD
-TOP-D
-TOP-Z
-TOP-RL
-SE/SE-TW
are utilised in air-conditioning/cooling applications, no vapour-proof
insulation is permitted to cover the drain labyrinth between the pump
housing and the motor. This is to ensure that any condensate having
possibly accumulated in the motor can drain off freely through the
condensate drain openings in the motor housing.
The Wilo-ClimaForm vapour-proof insulation that is obtainable as an
accessory for the Stratos, TOP-S, TOP-RL and SE series for insulating
pump housings in cold water applications guarantees this automatically,
thanks to its specific construction.
