Rothenberger RP50 problems

[stratplus]

Anyone had any experience with one of these?
I now have one where after only a couple of pumps it locks up and won't pump anymore.
Any ideas as to why?

admittedly i dont own the rp50 but i too have issues with the rp30 version. Mine seemingly seized? although a bit of brute force and the a good old kick did the trick. Must admit im not overly impressed with the quality for the money?

The RP50 is a good piece of kit. I have a couple of RP30's, not a patch on the RP50 though. Spare parts are easily available at a decent price but this locking up business has me stuck.

have you stripped it ? might be a split o ring catching

I haven't removed the plunger but I have taken everything else to bits. Split o ring around the plunger perhaps? Could this cause it to lock up? Got other rp50's where the o ring around the plunger leaks to buggery but still pumps perfectly.

maybe and if the tolerances are that tight it doesnt need much

Worth a try I guess. Thanks Shaun.

Its bewildering that a metalic box with a little leaver hand pump and a pressure gauge costs 250 quid. Surely it they can manufacture it for about a tenner

Mine locked up a few yrs back and seem to remember a non return type valve with a ball bearing in it being faulty
But can't be sure if I repaired it or replaced it

I found a bit of grease and brute force sorted mine.
