Built to a high standard, fit and finish is good, with nice detail touches like threaded jacking holes in the cylinder covers.\u003cp\u003e\u003c\/p\u003e\u003cp\u003e    Currently mounted on a wooden base for display, it's crying out to be taken off and bolted to the smokebox of something large and narrow gauge - think Tinkerbell, Thomas II (even, dare we say, one of our own Big Staffords or Feldbahns).\u003c\/p\u003e\u003cp\u003e    It starts easily and can be throttled back to run at a slow rate. Glands at the top of the water cylinders leak slightly.\u003c\/p\u003e\u003cp\u003e    Running well on air, it would settle to a more even beat running on steam and pumping against the back pressure of a boiler instead of simply circulating water around a plastic pot. \u003ca href=\"https:\/\/www.youtube.com\/watch?v=--GP_GKyULQ\" target=\"_blank\"\u003eThere's a video of it running at a slow tickover here\u003c\/a\u003e - at that speed it pumps around 400ml per minute.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54020019257685,"sku":"9144","price":875.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/9144-1.webp?v=1779909632","url":"https:\/\/stationroadsteam.com\/products\/duplex-steam-pump-stock-code-9144","provider":"Station Road Steam","version":"1.0","type":"link"}
