Frequently Asked Questions


What are the power requirements for my pump?

This question comes up often, it differs from pump to pump.  Please see this chart to determine what power you need:

Patch Pump/Spray Buddy 115V 15 full load amps
RS24E 208-240V 20 full load amps
30E 208-240V 30 full load amps

How much life can I get out of my pumps wear items?

Each pump has specific parts that wear out over time while being used.  Here are some general guidelines to them, due keep in mind this all varies based of material and pressures.  A rotor/stator you can expect a minimum of 1000 bags of material with a maximum of 5000 bags. Drive pins should be replaced with every rotor change.  On our piston pumps you have parts such as the piston cups which have a minimum of 5000 bags with a maximum of 30,000 bags, as well as the balls and seats which should get you 10,000 - 30,000 bags before change out.


How do I replace a stator tube?

The stator tube change out is a very simple process, but it does have a few tricks to it.  Please reference this video we made on how to change one out.


My rotor/stator pump will not push out sponge balls.

If your pump has lost pumping pressure than you will have some worn components.  This will either be the stator tube, rotor, or both needing to be replaced.  

You can check the pump pressure with a gauge and it needs to read at least 100 psi in order to push the sponge ball.


My drive pins keep breaking on my 30E or Spray Buddy.

If you are constantly breaking drive pins on your rotor/stator pumps that is a good sign of a worn connecting rod or drive shaft.  We have replacement parts available on our web store https://shop.hyflexcorp.com/


Why won't my new rotor/stator pump turn?

In storage the pumps can be on the shelf for some time.  This can cause the rubber of the stator tube to stick to the rotor.  If this happens the pump will not turn.  This can easily be fixed by filling the hopper with water and putting the machine in forward and reverse multiple times to un-stick the rotor.


My 321 piston pump is only giving me half production?

There will be an obstruction in the lower intake manifold of the pump.  This is due to clumpy material, foreign objects, or dry material.  You would need to remove the lower manifold and clear the obstructions. See this video on how to remove the manifold.
