Water Pump Plastic Impeller (EG8054)

We can produce plastic impellers with material PPS+GF40 or PA66 according to customer's requirements.

What is PPS and why have they chosen to use it?
A) PPS is short for PolyPhenelineSulfide and is an advanced semi-crystalline polymer reinforced composite.
European car manufacturers' decision to implement PPS in their water pump design, this was a conscious, purposeful choice on their part. Where the Vw water pump was once a commodity product, it is now considered to be a crucial technical component of coolant and engine systems.
In the course of engine development, the engineer's primary target is to achieve the BEST engine performance and efficiency. In order to accomplish this, the Vw water pump needs to produce and maintain precise coolant circulation rates. These rates sustain optimal engine temperature, fuel economy, and emissions. Above all other tested products, engineer's found PPS to be the superior choice.

What makes PPS so great?
A) PPS has a heat tolerance of up to and over 400 F; Which is double the operating temperatures of the engine.
PPS has a high chemical resistance. This gives the water pump impeller a greater degree of strength over long-term exposure to high temperature and 'long-life' coolant.
PPS material is impervious to rust and resists corrosive breakdown.
The advanced composite of PPS provides an ideal water pump impeller weight. What this translates to is less wear and stress on internal bearings.
PPS allows for more elaborate impeller profiles. In other words, the geometry of the fins can be very complicated. Perfect flow rates can be more accurately achieved.
PPS is able to be manufactured smoother than other materials. This means less friction, less turbulence, and less cavitation while operating in the cooling system.
