Knapsack Pump Assembly Unit

This is the replacement pump and internal hose for our RS12 and RS18 knapsack sprayers.

Product code 7270 as described in the sprayer manual.

I have snapped the hose thread, can I replace just this part?

Unfortunately not as the threaded hose connection is part of the single moulded pump assembly meaning that it can't be replaced without the whole pump.

Can I use this part on all of your backpack sprayers?

No, this pump is only for our Mesto backpack sprayers therefore the RS12, RS18 and RS Alkaline sprayers. It will not fit our electric backpack sprayers nor the IK backpack.

Is this easy to change?

It certainly isn't technically difficult as it is just a case of unthreading a couple of connections however it could be described as a little fiddly as you are working in a confined space, so just take your time.
