Vacuum pump

[___\0/___]

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?

 

[sjt01]

We have had a GEA (not sure of the model) for over 10 years now, no problems at all. Most of the time it runs on tick-over, nice and quiet.

 

[Bramble]

We’ve got a GEA RPS 2800, working well but the service interval on the vanes doesn’t seem very long and they cost about £600 each time

We just fitted a varivac and did change anything else, was miles cheaper too.

Is this just a controller fitted to existing motor and pump ? Single or three phase?

Old pump is goosed so needs to be new.

Make sure there's a bypass to run the pump full speed in the event of the inverter failing or coming up a fault.

Two Delaval DVP pumps here one is ten years old, no trouble at all with pump, have had the vacuum sensor fail once.

Fitted to existing pumps, they switched out our single phase motors and put a inverter to run 3 phase motors, has been in since 2009 no problems.

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...

 

[Bramble]

No idea if it saves leccy, we changed ours when we put in a new parlour. Much quieter now, the pump runs at tick over most of the time so I assume it saves something

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.

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.

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.

Run as a pair, 30/60. That was pumps only, no motors.

We put in a Varivac probably 15 years ago, electric bill was down about £1K first year.

How much do they cost?

 

[Cows 'n grass]

How much do they cost?

About £3k now for an ABB unit to run a 3ph motor

Do you have one?
Is there any conclusive payback? Got a 6kW motor on my pump, for a 20/40, runs for about 5-6 hours a day including wash time. I guess as my electric price increases, as it almost certainly will , payback will increase.

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.
