Asked our dairy engineer this yesterday. He says it would take 5 years payback, wouldn't do it with a belt driven pump only direct drive but if you where buying new pumps and motors or a new parlour it would definitely be worth considering.Any idea how to cost whether or not it's worth doing?
Got very old fixed speed pumps here. Interested in changing but trying to quantify the potential leccy saving...
Sounds cheap! Do they run as a pair or a single and an emergency standby? How many units will they do? 14 point swingover here.We are on fingle phase. We've just replaced 2 vp77's with the same. £2500 for the pair v £15k? For variable speed with 3 phase convertors. I decided I would rather keep some cash in the business than spend shitloads again on the promise of future savings.
Do you have one?About £3k now for an ABB unit to run a 3ph motor
I’ve gea and a de-Laval on my parlour,as posted the gea is dearer for vanes,I’d go with the de-laval pump.We are putting in a new variable rate vacuum pump and we have a decision to make between the Delaval DVP 2000 and the GEA RPS 2100 power pack, both on three phase.
Both OK or worth avoiding 1 of them?
