Title: Very cheap diaphragm pump
Post by: Tony on August 12, 2012, 12:21:58 PM: http://www.ebay.co.uk/itm/1pcs-Diaphragm-Pump-Water-Pump-Voltage-12V-Flow-400L-H-Pressure-1-2AMP-/170894153852

£6.65 delivered - wonder if it's rated for continuous duty (drywash pump?)

Post by: Tony on August 13, 2012, 12:15:39 AM: My current drywash pump (diaphragm type) cost about three times that. Still going strong after a couple of years though.

Got to say I'm dreading winter 2012, even this summer making bio has been an utter chore. :(

My circumstances have changed a bit lately and I'm filtering without mains power at the moment so it'd be useful if I could find a cheap 12v pump that would do the job.

I was only using a little 240v 300w commercial dishwasher pump which probably didn't push much more than a litre or two a minute anyway so I may even improve performance.

Post by: nigelb on October 05, 2012, 07:35:21 PM: Mine turned up a few weeks ago.....not sure what I'm going to do with it. I did think of mounting it in a housing and fixing it inside my boot and wiring it direct to the fuse box with a switch for re-fueling on the move.
