We design and manufacture special lines of mechanical seals for the household appliance sector.

We offer mechanical seals for dishwasher pumps for both domestic and industrial use. Starting from an assessment of use, it is crucial that their leak tightness and quietness level be as high as possible. These parameters must be guaranteed over time to avoid malfunctions that could then affect the effectiveness of the appliance. 

In addition to being fully customisable, these models are characterised by: long service life, high reliability, quiet pump operation (very good Db), excellent motor starting torque after prolonged standstill. 

The mechanical seal for dishwasher pumps is also achieved through a combination of certain materials, including a special type of PTFE (Mecflon) which is researched and developed by staff in our laboratory.
