Graf and Hepu make 12v metal impeller pumps, direct fit no mods.
Pros: direct fit, no mods
Any replacement whether it br Graf or Hepu are going to have a metal impeller and be an exact factory replacement. The wheel itself will be identical in shape and circulate the same volume of coolant.
Pros: exact factory replacement
I ordered one from MJM Autohaus, a Hepu unit and its impeller is metal
Pros: metal impeller
Part number: P525
Metal impeller model is available but can be hard to find (Hepu brand). Recommended interval for changing is 80-100K depending on who you talk to. But many fail earlier and may fail as early as 20k. Change as preventive maintenance.
Pros: metal impeller available
Cons: may fail early
Vehicle:
Volkswagen
The waterpump in my kit from germanautoparts.com was made by Hepu.
Pros: Hepu waterpump included
I have the Hepu unit in my car. It's been going great for the past 45k miles. Both are good options. I would go with what is cheapest.
Pros: going great
Mileage: 72000 km
I'll confirm that too (don't remember if it was iron or steel though). But I was highly skeptical too until I saw it w/ my own eyes. But definitely metal, made by German aftermarket manufacturer Hepu, AND it was cheaper than the OEM one w/ plastic impeller. Also that description on ECS's website must have changed recently because when I bought it, there was no mention of the impeller being metal. But Tom@ECS came on here and confirmed it. Still begs the question though if a metal impeller is really any better than the plastibake one if you change it out w/ the belt at 50-60K. I wouldn't hesitate to switch back to the plastic one if that's what I had on hand.
Pros: metal impeller, cheaper than OEM
Cons: uncertain long-term benefit
This was a Hepu pump. With far less than 60k miles. I'm thinking the coolant had gotten too old. Can't figure why else the pump would wear so fast. Noise statrted after coolant change, am running an AC delete setup.
Cons: pump wear fast, noisy
Vehicle:
Volkswagen
Mileage: 60000 km
I just lost my motor on christmas day due to water pump failure (hepu brand)
Cons: motor lost due to failure
Vehicle:
Volvo S70
