We fly-spargers want a consistent, low flow rate from mash tun to kettle. A ball valve (or Blichmann "linear flow" valve) works fairly well to regulate flow, but sometimes frustrates: setting the desired rate is kinda tricky, and can be bollixed by a bit of malt debris.
For under $100 (some under $50) on Amazon/eBay/AliExpress, there's quite a few peristaltic pumps that could allow well-controlled sparge rates. Most are too slow, but some can move 500 ml/min, about an hour to move a 7-gallon/30-liter pre-boil volume into the kettle. A few of these low-priced units can go much faster. Some come with speed control, but others might need external electronics.
Does anyone have experience with a peristaltic pump that you'd be willing to share?
