Safety
Certain warning symbols are affixed to the machine and correspond to notations in this
manual. Before operating the system, identify these warning labels and read the notices
described below. Not all labels may be used on any specific system.
Always wear approved safety glasses when you operate or work near the
workcell.
Before you operate the system, read and understand the manuals provided
with the unit.
Never put hands or tools in areas with this symbol when the machine is in
operation. A dangerous condition may exist.
Read and understand the manuals provided with the unit before any repairs
or maintenance is done. Only a qualified individual should do service.
Use caution when there are pressurized vessels. Find and repair any leaks
immediately. Always wear appropriate safety equipment when you work
with pressurized vessels or vessels that contain chemicals
Shear hazard from moving parts. Avoid contact.
Do not remove protective guarding.
In situations where inattention could cause either personal injury or damage
to equipment, a warning notice is used.

The PCP Series of progressive cavity pumps feature a machined rotor that couples with a
rubberized seal to assure drip-free operation with a wide range of viscous chemistries.
Each servo-controlled rotor displaces a fixed volume of material per revolution. This true
positive displacement process assures consistent volume regardless of slight material
variations.
The PCP Series features five different rotor sizes allowing the end user to select their ideal
flow rate. An optional carbide rotor allows processing of filled or abrasive chemistries while
extending the life of the rotor.
Theory of Operation
The PCP Progressive Cavity Pump is a high precision, rotating, positive displacement
pump. It dispenses high precision beads or dots of almost any chemistry or viscosity.
The pump contains a stainless steel or carbide rotor and an elastomeric seal (stator). The
PCP uses the principal of the “endless piston,” and is a progressive cavity pump that
provides pulse-free, drip free dispensing. Reverse operation of the pump will cause “suck
back” or “snuff back” which gives excellent shut off.
