De Laval 1950's Questions?

Anonymous-0 · Nov 16, 2008

Did the vacume pump have what De Laval called the pulso disk like they used in the 1920's or did the latter milkers from the 1940's and 1950's use a pulsater like whats in milking equipment now?

I have an old Delaval vacuum pump from that era, can't think of the model number now but it is old enough it has steel veins not fiber like anything in the last 40 years. It is just a normal vacuum pump that we used to run pneamatic pulsators on either surge or delaval buckets. I think I know what you are asking about, I think they are actualy from the 60s, the back of the pump had a generator that created juice to run the first type electronic pulsators. I saw a guy one time that something in his system went bad so he jigger rigged it by hooking up a battery charger to the system to run the pulsators. Not a good idea. This same guy had a water line break to the cups one time and it was to much work to fix it, so he just hooked up a garden hose with a float to the recesses manger. Put the cows feed out in front of the manger where they couldn't reach it while laying down in the stanchion. They quit using the silos because they were just to much work, so all the cows ate for forage was those goofy AC roto bales.

We had a De Laval milker back in the fifties. It was a large stand up aluminum bucket with a pulsater mounted on the top cover. It had a hook on each side that held a milking unit so you could milk a cow on each side of the bucket or just use one if needed. It had just an ordinary vacuum pump that I believe was run with a flat belt.

the ones we have are about 12 years old or so now.They have 2 coils inside that are twisted ontop of a plastic template with soft rubber gaskets and plastic plungers underneath.They don't make the sqush sqush sounds like the old ones,are quick open and close,make more of a tap sound.

Our 50's vintage had a vein type pump that you had to keep a small bottle of oil in, upended, to lubricate. Also had an electric switch on the end of the pump, a little mercury bulb, that controlled the electric pulsators. Milkers were cannister style, and had one claw, which operated two cups at a time, alternately. Electric pulsator was in hose that connected to overhaed vacuum line, and fed double hose down to milker cannister. A secondary pulsator controlled the cups from there.
