    Going through the shed the other day and came across this pump I forgot I had. I believe it is some form of irrigation pump and is marked as “wizard boil simplex”. I have tried searching this but google has not been very helpful in finding out more information. Dose anyone know anything about these?

    B.O.I.L stands for British Overhead Irrigation Ltd. So can assume it’s from one of their irrigation systems, dating from the early 1950’s onwards.

    Bits of info say that the Wizard Simplex was an oscillator irrigating crops 25′ to each side, does this sound right?

    B.O.I.L were for many years based at Upper Halliford, Shepperton, Middlesex. I’ll quote the text: “They specialised in artificial rain equipment, the principle being the projection of jets of water in such a way that it atomises and falls naturally to simulate rain”.

    Looking closely at the photo it does say Shepperton.

    Hi, Robert,

    How does the pump drive? I can see that it has two horizontally opposed cylinders with some sort of arm to make them move from side to side, but how does this arm move? A few more pictures may be helpful if you’ve got the time.

    Thanks again.

    We think that it worked off a pressurised system so the flow
    of water kept the pump working. Probably in a overhead system
    in large glasshouses or market gardens.

    Thanks for the information alan. With this I managed to find another post on the forum dealing with a different sprinkler but showing an advert for this one. Obviously I was wrong thinking it was a pump where it is apparently a sprinkler.

    Geoff the central arm move side to side and has a toothed rack on it. This connects with a toothed gear below that actually makes the output shaft (photo 2) rotate side to side. I guess this is where the sprinkler head fits. I will take a couple more photos when I am in the shed next weekend.

    I never thought to look at the VHGMC stuff, instead I looked through some magazines! That’ll teach me!

    Many thanks for linking the two threads together.

    As requested some more photos of the workings. I think the central toggle controls which cylinder the water goes to.
