Had local dairy engineer around the other day due to coolant leaking on milk tank compressor. After fixing that he started the machine for a quick look see. Its a 10unit Alfa Laval parlour. He then announced the double diaphram milk pump was dying. Its a DE15 Flowmax International New Zealand. Its not the bearing they are all perfect, there is a tick out of it when it comes under load.
Anyone ever rebuilt one, Ill guess the answer is not.
As double diaphram pumps are semi obsolete, we will be looking at Electric Milk Pump. For those who dont have variable speed - how do you throttle back the milk flow. No way could you have enough water to cope with the flowrate from the electric milk pump.
For variable speed milk pump I guess the level probe in the 10gallon milk Jar at the front of the pit is different for variable speed, and this is the expensive bit.
Is variable speed worth it after all that
