| 1159969 | 2010-12-08 23:03:00 | I have decided to get on to one of my pump projects and finish (or start rather) restoring an old McEwans style bulldoze pump. So far I have got most of the oil and grease off it and i'm starting to work on the paint job. right now i'm using some sandpaper and a steel brush to get rid of the paint and light surface rust. Of course sanding is not really a good option so what is a good way to get rid of paint and rust. Having a look around there are general metal paint/rust strippers that sound expensive. someone also mentioned soaking the metal in a hot caustic solution. That leads me to think, how hot? how caustic? can anyone give any advise/solutions or recommend products? Preferably cheap but i'll end up doing what it takes I guess. Cheers About: The pump was partially buried in sand, as well as being on its side, these things have a large gearbox that is full of oil so most of the gearbox end is coated with a sandy oil mix that has baked on a bit resulting in a tacky tarry coating, most of that has gone now though I plan to restore the pump so I can use it to pump water from the irrigation drains into the top dam (quite a height) and so I can free up the old diesel pump, which is a centrifugal pump and more suited for applications that require a constant water flow. Thanks for any help. |

| 1159972 | 2010-12-08 23:17:00 | Would complete stripping and sandblasting be an option? I was thinking about sandblasting when I first acquired the pump, I might have a look to get a quote, problem is it's bloody heavy. i'm just wondering whether its practical or not |

| 1159974 | 2010-12-08 23:38:00 | How big is it? Be best to pull it apart and sandblast it but I guess you dont want to pay for new seals if you can get them. I bought a $30 blaster fron super cheep auto use sand from the beach after sieving and drying it to do smallish jobs. But need a grunty compressor 3 phase to keep up with air demand |

| 1159976 | 2010-12-09 00:10:00 | Andrews Paint Brush and Roller Cleaner (or equivalent) will easily shift paint and congealed oil & grease. I use it for all sorts of cleaning tasks around the Man-Shed, including glueing plastics!. Apply it with a paint brush, leave for a while (keep it refreshed though, it evaporates fairly quickly) and scrape/wire-brush off the residues. It is not expensive and is water clean-up. It doesn't work as well on some very hard but thin paint coatings, but it still shifts them, just needs more elbow grease. Keep the breeze behind you while using it though, or you'll be found wandering down Main Street naked and singing disgusting stag-night drinking songs as it is rather volatile. Breathing it for too long or in an enclosed space is a mind-altering experience. Cheers Billy 8-{) |

It used to be a sand trap pump, long story short, the cups and piston were scratched to bits, I might get a new one machined! its not that big, just heavy. I also need to get a new cam and gears as I think it was run with sand in the gearbox, gears are almost worn through. I'm getting an air compressor to paint the house with (hiring) so i might just get a big one, depends what the most practical solution is What about steam cleaning? Steam might get the oil, I have a wallpaper steamer I could use bit I doubt the paint will come off with that Andrews Paint Brush and Roller Cleaner (or equivalent) will easily shift paint and congealed oil & grease. I use it for all sorts of cleaning tasks around the Man-Shed, including glueing plastics!. I might give that a go, either that or i'll give these people a bell http://www.steamsand.co.nz/ Cheers for input guys! |

| 1159978 | 2010-12-09 05:55:00 | An industrial steam cleaner is a cross between a steam cleaner and a pressure washer, so not quite like a wallpaper steamer at all. Often used by mechanics (in the UK especially) to clean crud from an engine prior to working in it | gary67 (56) | ||
