PCD Pump User Guide Safety Notices
Safety Notices
Despite adhering to all applicable safety guidelines, some hazards remain which should be
taken note of for operation of the system:
CAUTION: Very high pressures can be produced, depending on the viscosity and speed of
rotation, and this could result in unintended spurting of medium. Check the flow quantity in
relation to the dispensing needle used.
CAUTION: For initial start up and after being refilled, air bubbles in the medium could cause
an uncontrollable spurting from the outlet nozzle. Only start production operation once the dispense pump has been completely bled.
CAUTION: Wear suitable protective clothing if chemical, corrosive, or dangerous
products are to be used. Note and comply with the safety stipulations and the
information from the manufacturer. Ensure sufficient bleeding or extraction of air.
Take special safety precautions if working with dangerous media; for example, provide eye flushing facilities if working with corrosive chemicals.
CAUTION: Preparation before starting up - visual check. Make a daily visual check of the
dispense pump before starting work and before each shift change. If there is any doubt that the
unit is not perfectly ready for operation, it must be shut down at once and inspected by a suitably qualified person before it used again.

Introduction
The Progressive Cavity Displacement (PCD) Pumps are dispensing devices for precision work
with products requiring very high repeat accuracy with a wide range (low-to-high) viscosity.
These dispense pumps are true volumetric dispensing systems that can be dismantled in a
short period of time when maintenance is required.
Functional Description
PCD Pumps use a rotating displacement consisting of a rotor and a stator.
A number of voids are produced as a result of the various geometries of the conveying
elements. Conveying that is either proportional to the angle of rotation or else is RPMdependent (produced by the rotation of the rotor in the stator).
Since the direction of flow is reversible, the medium can be sucked back to allow a clean break
of the thread. Self-sealing depends on the viscosity.
Applications
PCD Pumps are classified by the minimum volume and the maximum flow rate. Compatible
fluids for all models generally have a viscosity of less than 60,000 cps and include fluid types
such as water, grease, gel, silicones, glues, LED encapsulants, underfills, fats, oils, colors,
sealing compounds, adhesives, etc.
Features
• PCD3 - The PCD3 model is designed for low volume applications with a minimum volume
of 1
• PCD4 - The PCD4 model is designed for applications with a minimum volume of 4
a maximum rate of 6 ml/minute.
• PCD6 & PCD7- PCD6 and PCD7 models offer a higher flow rate than PCD3 and PCD4.
PCD6 has a minimum volume of 15
has a minimum volume of 60
• H and L - Both H and L models benefit from lower priming volumes and air-free reservoir
change. H models use a high precision motor and may be used with the GPD stand-alone
controllers.
• PCD3H and PCD4H - These models offer higher resolution in dispense volumes. PCD3H
and PCD4H models include a low volume feed way for lower priming volumes and also
offer a higher resolution of dispense volume. Available only on MAX Series and DS Series
systems.
µL and a maximum flow rate of 1.3 ml/minute.
µL and
µL and a maximum flow rate of 18 ml/minute. PCD7
µL and a maximum flow rate of 60ml/minute.
Options
A material level detect option is available for all PCD pump models when used on these GPD
Global platforms: MAX Series or DS Series.

Maintenance
Cleaning Time
Cleaning a pump requires 15 minutes or more. The amount of time required relates
directly to type of material and solvent used.
Cleaning Kit
PCD Pump Series Cleaning Kit (PN 22110467)
Kit contents are illustrated in this document: KITS: Spare Parts/Setup/Cleaning (PN
22290036).
Cleaning Frequency Guidelines
Initially, a once a month inspection and cleaning is recommended, then based on your
experience using with the pump and fluid, extend or shorten the cleaning interval as
needed.
Cleaning frequency is determined according to the type of fluid being dispensed. For
pumps in continuous use, clean in intervals no greater than 3 x fluid pot life. For
pumps dispensing fluids stable at room temperature and that have no significant pot
life issues, the pump may be run continually without issue.
Cleaning Procedures
• Flush Pump
• Clean PCD3, PCD3L, PCD3H
• Clean PCD4, PCD4L, PCD4H, PCD4HB, PCD6, PCD6HB, PCD7H
(pg 12)
(pg 13)
(pg 17)
Flush Pump
The flush procedure is used primarily when underfill material needs to be purged from the
pump. The dispense tip and needle can be removed or left in place:
• The dispense tip may be left in place or removed during the flush procedure.
• If a disposable needle is present, remove and discard it.
• A needle intended for reuse can remain in place on the pump as the flush procedure will
clean the needle.
To flush fluid from the pump:
1. Remove the fluid reservoir from the pump.
2. If present, remove disposable needle.
3. Install an empty syringe on the pump.
4. Fill the syringe with a suitable solvent.
5. Set the pump to purge into a purge cup or suitable container.
6. Continue to purge until all dispense fluid has been purged and only solvent is exiting the
pump.
