To replace the 6 inlet and discharge valves on the XWP series triplex plunger pumps remove the valve caps on the manifold with a 32mm socket

Next, using a pair of needle nose or valve pliers remove the valves by grabbing the plastic valve cage while twisting and pulling straight out

The inlet and discharge valves may look similar but they are not the same.
The bottom inlet valves have a silver spring with less resistance and the discharge valves on the top have a black spring with more resistance

Make sure to clean the thread sealer off of the plugs and the ports for your valves to prevent damage when reassembling it

Put in the new valves, making sure they are properly seated and in the correct spot

Apply a thin layer of thread sealer all the way around the threads when reinstalling the valve caps

Make sure to torque the caps to 2212 Inch pounds or 185 foot pounds before the adhesive dries

Never use the airgun when re-assembling your machine because this can lead to injury to you or damage to your pump

To access the pistons and their guides start by removing the 8 head bolts with an 8 MM allen socket.

To take off the head, rotate the crankshaft with a wrench to help push it off of the pistons

This allows enough space to support the bottom of the head and push off with your thumbs

Be careful not to apply too much pressure to one side of the head because this can crack the ceramic pistons

Once the manifold is off there will be parts either on the pistons or still in the head of the machine.

To remove parts off of the pistons start by using a wrench or your hand to rotate the crankshaft, this will push the parts towards the end of the piston making them easier to twist off.

The best way to take the parts out of the head is to use a rear piston guide extractor, which we sell on our website.

If the seals can’t be taken out by hand, use a small flathead screwdriver to pry them out without scratching the inside of the pump.

The first item to go into the manifold will be the head ring with the flat side facing down
Next comes the high-pressure seal, its concave side should fit over the support ring
New seals are tough to fit in, make sure to work them in at an angle and to only use your hands
The front piston guide comes next with its smaller side going into the head first
To put the rear piston guide in first replace the o ring on the outside, then place in the brown backup ring into it

The low-pressure seal goes on top of the backup ring with its concave sticking out of the guide

If the guide is put in squarely it should click into place

To replace the pistons, remove the piston bolt using a 10 mm socket.

If you are not replacing the pistons make sure to scrape off any residue that has accumulated on the outside

Make sure to Scrub off anything you missed with the knife

Once your parts have been thoroughly cleaned you can put the copper plate and the piston back on

Add the copper washer back on and Again, make sure to clean off any thread sealant from the bolts before putting them back in
Now we can apply a small amount of thread locker all the way around the bottom on the piston bolt before retightening them

Torque the piston bolt to 62 inch pounds

To properly put on the manifold turn the crankshaft so that the outer pistons are even
This helps with pushing the head back on squarely

New seals may be tight, so you can use a soft faced hammer to evenly tap the head into place while supporting it

These head bolts should be torqued to 442 inch pounds or 37 foot pounds

Torquing in a crisscross manner can help evenly tighten the head onto the pump.

These are the tools used in the video to repair the machine

Here are the kits and their parts numbers needed to service the pump

To replace the 3 discharge valves on the top of this pump, remove the valve caps on the manifold with a 24mm socket

Next, using a pair of needle nose or valve pliers remove the valves by grabbing the plastic valve cage while twisting and pulling straight out

Make sure to clean the thread sealer off of the plugs and the ports for your valves to prevent damage when reassembling it

Put in the new valves and make sure they are properly seated

Its ok to use something that you have a firm grip on and that will not damage the inside of your pump to make sure they are in all the way

Make sure the backup ring is correctly fitted in the groove of your valve cap to prevent damaging it when putting the caps back on

Apply a thin layer of thread sealer all the way around the threads when reinstalling the valve caps

Make sure to torque the caps to 531 Inch pounds or 44 foot pounds before the adhesive dries

Never use the airgun when re-assembling your machine because this can lead to injury to you or damage to your pump

To access the inlet valves, pistons, seals and their guides start by removing the 12 head bolts with a 6 MM allen socket.

Watch out for this small o ring that could fall out during servicing, without it. Your pump will end up leaking.

To remove the valves start by taking off the o rings near the valve. Be cautious not to pierce your o rings or they will have to be replaced.

Now you can take a pair of valve pliers to twist and pull the valve straight out
If you are not replacing your valves check the springs to make sure they are functioning properly

Then you can put the valves back into place, followed by the oring

To access the other components in the head remove the 8 other headbolts with an 8mm allen socket

To take off the head, rotate the crankshaft with a wrench to help push it off of the pistons

This allows enough space to evenly pry off the head with 2 screwdrivers on opposite side of the pump

After that, support the bottom of the head and push off with your thumbs

Be careful not to apply too much pressure to one side of the head because this can crack the ceramic pistons

Once the manifold is off there will be parts either on the pistons or still in the head of the machine.

To remove parts off of the pistons start by using a wrench or your hand to rotate the crankshaft, this will push the parts towards the end of the piston making them easier to twist off.

To take the rear piston guides and flow-pressure seal out of the head the best method is to use a pair of channel lock pliers to twist and pull them out

Next, take out the front piston guide

If the high pressure seals can’t be taken out by hand, use a small flathead screwdriver to pry them out without scratching the inside of the pump.

The first item to go into the manifold will be the head ring with the flat side facing down
Next comes the high pressure seal, its concave side should fit over the support ring
New seals are tough to fit in, make sure to work them in at an angle and to only use your hands
The brown backup ring should then fit on top of that

The front piston guide comes next with its smaller side going into the head

To put the rear piston guide in first replace the o ring on the outside, then place in the brown backup ring into it
The low pressure seal goes on top of the backup ring with its concave sticking out of the guide

The small support ring will fit into the seal with its curved side down, make sure to put a small amount of grease onto the ring so that it stays into the seal when you put the guide back into the head

If the guide is put in squarely it should click into place

If you are not putting on new pistons, you can use a knife to remove debris on the piston

Scrubing and wiping them off is also important to do.

To replace the pistons, remove the piston bolt using a 13mm socket.
Take off the brass plate in any fashion that does not end up bending it out of shape

Again, make sure to clean off any thread sealant from the bolts before putting them back in

If you are not replacing the pistons make sure to scrape off any residue that has accumulated on the outside
Once they have been thoroughly cleaned you can put the copper plate and the piston back on

There is a small o ring hidden in the piston bolt, make sure to inspect this to ensure it hasnt been damaged

apply a small amount of threadlocker all the way around the bottom on the piston bolt before retightening them

Torque the piston bolts to 177 inch pounds

To properly put on the manifold turn the crankshaft so that the outer pistons are even
This helps with pushing the head back on squarely

New seals may be tight, so you can use a soft faced hammer to evenly tap it into place while supporting it

These head bolts should be torqued to 442 inch pounds or 37 foot pounds

Torquing in a criss cross manner can help evenly tighten the head onto the pump

Dont accidentily install the inlet manifold on upside down. The words in should be the right way up when put on right

Do not remove these, they are machining ports.

This video will cover how to replace the Inlet and discharge valves along with the pistons, guides and seals on any Annovi Reverberi AR RGX series pump.

These are the tools used in the video to repair the machine

Here are the kits and their parts numbers needed to service the pump

To replace the 3 discharge valves on the top of this pump, remove the valve caps on the manifold with a 24mm socket

There are 6 valves in total, the other 3 require the head bolts to be taken off

Next, using a pair of needle nose or valve pliers remove the valves by grabbing the plastic valve cage while twisting and pulling straight out

Make sure to clean the thread sealer off of the plugs and the ports for your valves to prevent damage when reassembling it

Put in the new valves and use something that will not damage the inside of your pump to properly seat them

Apply a thin layer of thread sealer all the way around the threads when reinstalling the valve caps

Make sure to torque the caps to 531 Inch pounds or 44 foot pounds before the adhesive dries

Never use the airgun when re-assembling your machine because this can lead to injury to you or damage to your pump

To access the remaining valves, pistons, guides and their seals start by removing the 8 head bolts with a 8 MM allen socket.

The inlet manifold should come off with the head bolts

There are several ways to remove the inlet valves with the first being a 12MM bolt, whos threads match up with the valves

Next is a pair of valve pliers

Third is the reverse pliers, where you twist and pull to take the valve out.

Use a pick to take out the old o rings near the bottoms of the valves

Watch out for this small o ring that may fall out, without it. Your pump will end up leaking.

Put in the new o rings, followed by the new inlet valve

To get to the pistons, seals and their guides, we need to remove the head of the pump
The best way to remove the it is to support the bottom while tapping the top with a soft face mallet.

Do this until there is enough room to evenly pry off the head with 2 screwdrivers on opposite side of the pump

Be careful not to apply too much pressure to one side of the head because this can crack the ceramic pistons

Once the manifold is off there will be parts either on the pistons or still in the head of the machine.

To take out parts still in the head you can use a rear piston guide extractor, which we sell on our website.

After that, Take out the front piston guide by hand
A small flathead screwdriver can be used to pry out the high pressure seal if it can’t be taken out with your fingers.

To remove parts off of the pistons start by using a wrench or your hand to rotate the crankshaft, this will push the parts towards the end of the piston making them easier to twist off.

The first item to go into the manifold will be the head rings with the flat side facing down
Next comes the high pressure seal, its concave side should fit over the support ring
New seals are tough to fit in, make sure to work them in at an angle and to only use your hands
The brown backup ring should then fit on top of that
The front piston guide comes next with the angled side going into the head
To put the rear piston guide in start by replacing the o ring on the outside, then place in the low pressure seal with the flat side first into the guide
Put a small amount of grease onto the support ring so that it stays in the seal when putting in the head

When properly seated it should click into place

To replace the pistons, remove the piston bolt using a 10mm socket.

Again, make sure to clean off any thread sealant from the bolts before putting them back in

Now you can replace the brass plate, followed by the new piston

Add the copper washer to the piston bolt along with applying a thin layer of thread sealer all the way around the threads before retightening them

Torque the piston bolt to 62 inch pounds

Now we can place the manifold back onto the pistons and reapply the head bolts

To properly put on the manifold turn the crankshaft so that the outer pistons are even
This helps with pushing the head back on squarely

New seals may be tight, so you can use a soft faced hammer to evenly tap it into place while supporting it

These head bolts should be torqued to 442 inch pounds or 37 foot pounds
