Katadyn Hiker Pro Pump Plunger Set 2
the pump mechanism as a spare part
Plunger running rough, grip sleeve damaged, pumping suddenly taking effort? Then it is not the filter that is faulty but the mechanism – and here it comes complete.
Buy the Katadyn Hiker Pro pump plunger set – renew the pump mechanism
The Katadyn Hiker Pro pump plunger set (Set 2) contains five parts for renewing the pump mechanism: the pump plunger itself, its matching O-ring, the grip sleeve, the bushing and a tube of silicone grease. It lets you replace the entire moving internals of the pump handle instead of collecting individual small parts. Usefully, the set fits not only the Hiker Pro but also the Hiker with the grey pump handle – an advantage for anyone still running an older unit.
Mechanism, not prefilter
How to tell it really is the plunger
On the Hiker Pro two quite different causes lead to the same feeling – pumping becomes hard work. One is a clogged filter element: resistance then rises gradually over weeks, and less and less water arrives despite vigorous pumping. The other is the mechanism: the plunger then feels rough, jerky or uneven, scrapes audibly, or the grip sleeve has come loose and turns with it. A simple test helps: take the filter out of the water and pump dry. If the plunger runs rough or jams, this set is the right choice. If it runs cleanly, the cause is the filter element or the prefilter.
Why the bushing and grip sleeve are included
The plunger alone would often not solve the repair. The bushing guides it and keeps it on axis – if it is worn out, even a new plunger runs skewed and wears its O-ring out again within a short time. The grip sleeve, in turn, is the part you actually pull on while pumping: if it comes loose or tears, pumping becomes unpleasant and, when wet, unsafe. Katadyn therefore includes both parts in the set instead of offering them individually – they wear out in the same period as the plunger anyway.
Also for the Hiker with the grey pump handle
The Hiker Pro is the successor to the Hiker, and Katadyn kept the pump mechanism compatible. This set therefore also fits the older Hiker, provided it has the grey pump handle. That is useful for anyone wanting to keep an older unit running: as long as filter body and housing are intact, a new plunger brings the Hiker back up to standard without a whole new unit being due.
Silicone grease – and why dry fitting does not work
A plunger works against the cylinder with every stroke. If its O-ring is fitted dry, it twists during assembly, runs skewed from the start and chafes through within days. That is why a tube of silicone grease comes with the set: applied thinly it eases fitting, reduces friction and keeps the elastomer supple. Use silicone grease exclusively – mineral-oil lubricants and petroleum jelly make many seal materials swell.

Set 2, Set 1 or filter element – check first, then order
On the Hiker Pro a short dry test pays off before ordering: take the filter out of the water and pump. If the plunger runs rough, judders, or the grip sleeve is loose, you need this pump plunger set. If it runs cleanly and flow is still weak, the cause is the prefilter or the filter element – then the maintenance kit (Set 1) with filter guard and mesh, or a new filter element, is the right choice. Anyone travelling a lot keeps both sets on hand: Set 1 as a consumable, Set 2 as an emergency reserve.
