Description
TRW tops benchmark tests for wheel pumps
In a benchmark study testing the durability of TRW’s wheel pumps against two leading competitors, TRW came out on top with a lifespan average of over one million cycles, 16% more
than the nearest competitor.
In further tests of contamination and end of line controls, the results included:
– Contamination of aluminium particles in the sealing area by competitor 1 and steel particles by competitor 2
– Seals either missing completey from competitor wheel pumps or seals fitted the wrong way round
3 year guarantee
TRW are so confident in the quality and testing of our wheel pumps that we offer a 3 year or 100,000 km guarantee instead of the legally required 2 years.
100% end of line testing
TRW conduct 100% end of line pneumatic testing with complete accuracy assured by sensors within a resolution of 1,000,000. The test is conducted using the manometric method, which by
employing absolute pressure decrease is reliable, repetitive and safe.
OE specification seals
All TRW rubber components have to fulfill the following OE acceptance criteria:
– High Tensile and Tear strength
– Low compression set (20% max)
– High resistance to ageing in air at high temperature (150 – 200°C)
– High resistance to brake fluid at high temperature (4 weeks at 150°C)
No.1 in TecDoc application coverage
There are more than 650 references in the TRW wheel pump range making TRW number 1 in TecDoc wheel pump parc coverage.
PCRVi
TRW wheel pumps with PCRVi fulfill the highest technical standard in order to reliably reduce the brake pressure build up at the rear brake. If the valve fails, the rear axle may lock,
and drivers may lose control of the car.
Aluminium wheel cylinders
TRW also offer aluminium wheel pumps including aluminium pistons. Housings and pistons are anodized providing a corrosion resistant and wear-resistant surface. Competitors
often have cheaper steel pistons that are at risk of corrosion if not surface-treated.
