Patented Water Pump by AIRTEX
About a year ago the 1953 water pump was launched into the market, after a great design work carried out by the entire AIRTEX team.
But, what is a „PSF“ Water Pump?
PSF stands for „Pneumatic Switched Flow“. Through a vacuum process, the water pump varies the flow rate according to the requirements of the engine, improving its performance.
Following the link below you can access a document where you can find information about the behaviour and benefits of this system.
The 1953 reference has applications for a wide range of VAG group vehicles, such as Audi A3 ’10, Seat Ibiza IV, Skoda Octavia II, Volkswagen Golf VI, etc. which have a European park of approximately 3 million units in Europe.
Specifically, this pump is mounted on the 1.2 TSi and 1.2 TFSi engines with 86, 90 and 105 HP.
