Old milking machine- convert to water pump?

millertime78

I have an old milking machine with a single phase brooks crompton electric motor, I'm wondering if it's possible to convert to a water pump- could be v useful in the hard frost!

Anyone have any suggestions of how to do this?

Well if the milking machine is a vacuum pump, you cant use it to pump water. Wrong material, seals etc.
If you want to just use the electric motor and use that to drive a seperate water pump, then that should be possible.

If it's a diaphram pump you would be plagued with tiny crap getting into the check valves and loosing pumping pressure, also the life cycle of the diaphrams would be short enough if you were pumping much water at any decent pressure.. Drawing water any head height into the pump will cause the diaphram to tear apart.

If it's a centrifugal electric pump remember it can only pump water that is gravity fed into it so will not draw water in at all, while they will pump a good flow rate at low pressures they don't produce sufficient pressure to pump any decent distance, again I'd wonder about shaft seals - maybe ceramic seals would be good enough but impellor wear would be expensive..

If you have them lying round you'd be better hock them on donedeal and buy a suitable pump..
