Title: HJ212 Impeller Identification
Post by: paul_mulujet on March 18, 2018, 10:07:24 AM
Is anyone able to identify this impeller from an HJ212 I acquired some time ago? It has the number 108162 stamped on it. I'm wondering what the kW rating is and if it is a 'turbo kit' or not. Thanks in advance for any info you can shed on this.

The pitch is usually stamped in just forward of the part number. It is hard to tell from the photo but to me it looks0 like a coarse pitch, maybe 3.4 kw
This photo is of a 2.4 and it shows where the pitch is stamped.

Good answers and thanks for the replies guys.

So it seems Hamilton is a little inconsistent with marking or stamping their impellers. I can't find the kW rating anywhere on the impeller in question yet I have another impeller on the shelf which is clearly marked with 3.4TBO next to the part number 108162. And then I also have 3rd and used impeller with no part number or kW rating at all marked on the metal. All makes for bit of a guessing game  ::)

Give Hamilton Jet a call, with the part number I'm sure they will be able to clarify. While you're talking to them ask about their latest impellor developments ....

Yeah, these impellers have been sitting around for a few years so would be good to know the latest developments from Hamilton. Will call them... Cheers Ross
