Description of Components
Component
Description
Electric Motor
The motor turns the rotor. Motor speed can be fully adjusted to
change the flow rate.
Rotor
The rotor is a stainless-steel or carbide helical shaft. A fixed
volume of material is moved as it rotates inside the stator and
uses the principal of the “endless piston”.
Stator
The stator is an elastomeric seal with a double helix molded into it.
The stator lets material flow when the rotor turns but has a
perfect seal when the rotor is stopped.
Manifold
The manifold is fed by the rotor/stator and supplies it to the
dispense needle through the material outlet.
Personal Protective Equipment
Operators must use eye protection because material contents are under pressure. Always
wear gloves when handling materials and solvents. Refer to MSDS sheets on the material
being dispensed for other precautions.
Waste Disposal
Dispose of all used parts and materials in accordance with local laws and regulations.
Necessary Tools
PVA offers tools and cleaning accessories to maintain the PCP progressive cavity pumps.

Setup
Before you operate the pump, know the pump components. Do the steps instructed below
for safe and correct operation.
WARNING: Never operate the pump dry. If the pump is operated dry or without pump
conditioner, severe damage will occur. Always put pump conditioner on the rotor
before the pump is assembled. Refer to Section 9 for more information on how to
order pump conditioner.
1. Use the mounting holes to install the PCP onto the workcell.
2. Attach the fluid supply line to the related fluid inlet.
Make sure the fluid fittings are tight and do not leak.
3. Attach the motor cable and make sure the routing of the cable is correct.
Make sure the motor connection on the pump is tight and that the prongs are not
bent.

Operation
WARNING: Never operate the pump dry. If the pump is operated dry or without pump
conditioner, severe damage will occur. Always apply lubricant to the rotor before the
pump is assembled.
Operation Notes:
• You must do the initial bleed for the pump to function correctly.
• Make sure the material is supplied correctly to the pump.
The sections that follow are in the recommended order to operate the pump. To operate
the pump, do every sub-section in Section 3, in the order shown.
Bleed the Pump
1. Open the bleed clip.
2. Turn the bleed clip counterclockwise to loosen. Turn one full rotation then slowly
until material appears.
3. Turn one full rotation and then slowly until the material begins to bleed.
4. Let the material flow from the material outlets until there are no breaks in the
material flow.
NOTE: Any break in the flow of the material shows there is still air in the system.
Bleed the pump until the material flows smoothly without any breaks in the flow.
NOTE: The fluid supply operating pressure must be have a flow rate equal to or more
than the maximum flow rate capacity of the pump.
5. Clean all material from the manifold and material outlets.
6. Close the bleed clip by spinning it clockwise until there is resistance.
7. Close the door of the bleed clip.
