Metal-edge filters

Features and Benefits

MAHLE means performance, and with over 95 years of rich heritage, MAHLE possess several attributes which gives the racers the competitive advantage they seek. The following characteristics are the “Features and Benefits” of the MAHLE piston which separate us from the competitors.

Ultra flat ring grooves, the key to power

Every MAHLE Motorsport piston is machined to exacting tolerances with focused attention given to the radial flatness of the ring grooves. A flat ring groove is essential in achieving and maintaining the best seal possible. The quality of the ring grooves is so critical to peak and lasting performance, that MAHLE designed and built the machinery used to machine the ring grooves for its MotorSport piston assemblies. Combined with ultra flat MAHLE rings that are included in every PowerPak piston kit, MAHLE delivers the formula for the best sealing power cell on the market.

A true performance coating

MAHLE Motorsports’ proprietary Grafal® anti-friction skirt coating is like no other on the market. It is graphite impregnated to reduce drag like many other skirt coatings, but this is where the similarities end. The screen print application provides superior adhesion and is designed to last 100,000+ miles. The unique properties of Grafal® reduce the harsh contact between the piston skirt and cylinder bore, resulting in much less wear on the bore and significantly reduced piston skirt fatigue.

Pin bores CNC machined for unmatched performance

Piston failures can often be traced back to poor and inconsistent pin bore quality or design. The pin bores on every MAHLE Motorsport piston are finishmachined using CNC equipment specially designed andmanufactured by MAHLE to precisely control shape, size and alignment. This added control allows for advanced designs and flexibility, resulting in unmatched consistency andperformance. MAHLE manages every small detail with the type of precision and expertise you would expect from the world’s piston technology leader.

The classic MAHLE metal edge filter range with connection sizes ranging from G 1/2 to DN 300 can be used for a variety of low to high viscosity liquids, pastes, and similar materials. Compact designs with one or more rotating elements offer ideal conditions for selecting the optimal model size. They come in a variety of designs and materials, facilitating a wide choice of applications - including high-pressure designs. Minor adaptations to available standard solutions frequently satisfy customer-specific requirements.
