Annovi Reverberi AR RTX series repair and maintenance video the on models RTX30, RTX50, RTX60, RTX70, RTX85 and RTX100 piston triplex plunger pumps. In this video, the AR North America technical team will be showing you do repair and maintenance step by step.
This video will cover how to replace the Inlet and discharge valves along with the pistons, seals and guides on any RTX series pump.
Here are the kits and their parts numbers needed to service the pump
The kits may vary depending on which pump you have
To replace the 6 inlet and discharge valves on this pump, 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
Note that the inlet and the discharge valves are different on this pump , the discharge vales on the top have a black spring and the inlet valves on the bottem have a silver spring.
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 in their correct spot 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
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 3540 Inch pounds or 295 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 a 8 MM allen socket.
To take off the head, rotate the crankshaft with a wrench or your hand if you can
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 guide and low pressure seal assembly 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 you cant take out the low pressure seal out by hand, use a small flathead screwdriver to pry parts out without scratching the inside of the pump.
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 rear support ring should then fit on top of that
The front piston guide comes next with its curved 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 brown backup ring into it
The low pressure seal goes on top of the backup ring with the bumpy side 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 13mm socket.
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
apply a small amount of threadlocker 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 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
