Duplex boiler feed pump
« on: June 16, 2021, 07:45:04 PM »
I bought a coal fired steam plant last week that included this boiler feed pump. It appears to be scratch built with great skill and it works perfectly.

Is it an original or can anyone identify the design?

Cheers Dave, I have run the steam plant for a few hours and the pump is fascinating.
 The previous owner inherited the plant several years ago and hadnít used it. He didnít know the history of the plant or who the builder  ĎH Forrester 1987í was so Iím unlikely to to unearth any information thirty four years on.

Hello Andy

I'm running on memory here so may be wrong but I believe your pump was designed and described by a Mr Austin-Walton years ago in Model Engineer magazine as part of his "Twin sisters" series of articles.

Hope this might be of help.

Best wishes
John

Thanks very much for that John well done. 

Using Google I have found these plans sold by Sarik Hobbies, I feel certain they are for the pump I have.

https://www.sarikhobbies.com/product/loco-feed-water-pump-plan/

The narrative states,

ď Loco Feed Water Pump (Plan) £13.00
Designed by J L Austin-Walton this plan is for building a twin cylinder, double acting steam pump for 1:12 scale steam locomotive.Ē

Hello Andy

I'm pleased to be of help, although, I remembered the spelling of his name incorrectly it should be Austen-Walton.

From my indexes the relevant articles are contained in issues 2577 and 2578 of Model Engineer Volume 103 pages 569 and 607  second half of 1950.

Best wishes

Thanks for identifying the two Model Engineer Magazines John. I bought them via eBay and they were delivered this morning. The article is a complete description of how to build the pump and it includes the drawings, Iím pleased to have the information.

I like that design. Now I'm going to have to make one. I've been wanting to build a steam pump for no particular reason.
