Ardes Manual Drench Gun

Lime Tree Farm

https://magentadirect.ie/product/drencher-non-auto-ardes-150ml/

I was given a loan of one of these and was very impressed with it. I then bought one and find it a pure pain to operate. I use vegetable oil to lubricate the seal on the plunger. It works ok to begin with the largest dose and wind down for lower doses, but comes apart, with the circlip popping off, if you reverse wind back up again to increase the dose. Did I get a dud, anyone else have the same experience.

Have one years and never came apart.
Definitely gets stiff to use.

Lime Tree Farm

Thanks Brian, I find it stiff also and have to forcibly pull back the plunger. I have been looking up Silicone lubricant for drench guns.

I think you need to use silicone oil instead of vegtable oil. I have a similar one here for years and I used vaseline and later veg oil on it. I had to take it apart and clean it always before using. Someone said to me to use the silicone oil.

You can buy silicone spray in Halfords.

Have one too. Same problem. I leave water in it when not in use and it seems to help stop it drying up

Lime Tree Farm

thanks for replies and where to get silicone oil.

I rinse it out in clean water immediately after use, especially with white drenches. Afterward use washing up liquid and leave it dismantled until next time.

I have an auto one, 60 ml, except for the capacity, never gave a bit of bother, just allow air into drench container when it starts to collapse.

I tried a bit of oil I had here for a hair trimmers (human type :cool:) and it worked a treat in my old doser. I imagine it is silicone oil of some sort.

I'd say you'd be fine with that food grade one. Strictly speaking it should be food grade, as it might in theory get into the food chain, but cattle lick all sorts of crap anyway. I'd be more worried about it reacting with the seal or o-ring in the syringe. Less likely to do that too, if food grade.

Lime Tree Farm

Thanks Patsy, I ordered it online just now. €15.94 from Ashbourne, Co. Meath.

It wont go to waste, worth trying it out.

I tried it on an old hand held drencher I have over 20 years and it seems to work alright.

I also got the Lidl Powerfix silicone oil, comparison below: (which doesn't mean a whole to lot to me).

Powerfix Profi Silicone oil contains:
Hydrocarbons, c7, n-alkanes, isoalkanes, cyclics
Hydrocarbons, c6, isoalkanes, < 5% n-hexane


Ambersil Food Grade, NSF H1, silicone lubricant contains:
hydrocarbons c3-4-rich petroleum distillate petroleum gas, (1,3-butadiene < 0.1%)
Naphtha (petroleum), hydrotreated light.

Both Powerfix and Ambersil brands have the exact same hazard warnings.
