Specialist pump and the machine its used in
🕑 Added 2024-03-26 05:03:24 +0000 UTCAlthough this video was originally going to be just about this application-specific pump, I thought it would be good to explore the technology of the machine it's used in.
Most of the components in these machines are a common rebranded type, so spares are readily available online. The unusual rubber impeller design means this type of pump might find other uses like lathe coolant circulation for a home workshop.

Thanks Big Clive. That's pretty neat! I was originally thinking that perhaps this used less energy than my 20+ year old Kenmore dryer (solidly reliable) but then you have to figure that water is water and Kilocalories are Kilocalories. I'm thinking the recirculation and drying of the working air must add to it's efficiency. I think that pump is pretty cool!

Interesting! I never knew there were dryers with heat exchangers that *weren't* using heat pumps. I'm in the US and just got a heat-pump dryer last year. It does need a 240v power supply, so it's not "plug in anywhere" here in the US, but there are some models that only require 120v. As others have noted, it takes longer to dry than the sort with an electric heating element, but it uses a lot less power and I'm very happy with it.

Oh if that's what i think it is (anmd it looks exactlty the same) it's one of the indesit models that was subject to the safety recalls - my ex partner's one had to have at least 2 modifications made by the manufacturer. It appears yours is a different age just by the power cord/plug thiough. Hers has a white cable .. and did have white moukded plug untiil it melted that & I replaced it. I've recently replaced my ancient vented dryer with a heat pump model. They have dramatically overcomplicated them - what was wring with "low/high" and time? .. tjhis has a bazillion of nonsense programmes and on at least one the last 15 minutes can take another 2 hours ... the state of modern software and user interfaces is dire .... but it does dry a much larger loads then my old one while using less power overall, so that's good. I will confess also that my buying devcision was swayed by one simple yet genuis thing they did on it .. I always found that water reservoir on the indesit a nightmare - awkwardly long, heavy, and guaranteed you a wet floor. The new Hovver models have the water tank inside the door window - it just lifts out/off vertically from the open door the water level is visible thriough the door.
