Airtex has revealed its electro-hydraulic control flow (ECF) water pump.
After six years of development, 6,500 testing hours, 50 prototypes and 120 hydraulic tests, this new ECF pump is an aftermarket alternative to the OE version that is used for 1.6 and 2.0l VAG engines (2012-onwards), which total more than nine million vehicles across Europe.
Airtex says, using a similar technology previously only available from the OEM, the water pump varies flow rate according to the requirements of the engine, which results in improved engine warm-up times, leading to gains in fuel efficiency and lower emissions.
However, the pump uses Airtex’s own patented SWITCH ECF technology to vary the flow rate, without infringing the original patent.
The Airtex ECF pump (reference 1978) is available as a single water pump unit, or as part of a water pump kit.
