PCD Pump User Guide Safety Notices
2/20/19 GPD Global®iii
Safety Notices
Despite adhering to all applicable safety guidelines, some hazards remain which should be
taken note of for operation of the system:
General Safety
Informal safety measures
• Always keep the operation and maintenance instructions with the dispense pump.
• This is to be supplemented by the generally and locally applicable rules and regulations to
prevent accidents and for protection of the environment.
Operating environment, prevention of damage
In order to prevent damage and to ensure chambers required for precise dispensing are filled,
make sure that:
• the dispense pump is never operated without medium (the stator will be destroyed),
• the discharge side is not closed off during operation.
Appropriate use, warranty
The dispenser pump is intended to be used for the conveying and precise dispensing of media
in non-explosion-proof environments.
Check the chemical resistance of the parts in contact with the product before starting up the
unit for the first time. Refer to Specifications (pg 23).
Any of the following that are done without the explicit and written approval of the manufacturer:
• conversions or additions,
• the use of non-original spare parts,
• repairs carried out by companies or persons that have not been authorized by the manu-
facturer
can lead to the warranty being rendered null and void. The manufacturer shall have no lia-
bility whatsoever for damage resulting from failure to follow the Operations (pg 8) and
Maintenance (pg 12) instructions.
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 dis-
pense 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, pro-
vide 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 suit-
ably 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 RPM-
dependent (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 1µL and a maximum flow rate of 1.3 ml/minute.
•PCD4 - The PCD4 model is designed for applications with a minimum volume of 4µL and
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 15µL and a maximum flow rate of 18 ml/minute. PCD7
has a minimum volume of 60µL and a maximum flow rate of 60ml/minute.
•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.
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.
