Versatile Pump Control SystemVPC™
The VPC™ system is a family of packaged
rod-pump controllers offering a range of
solutions in a single footprint. VPC™
units are available in four versions
• Stand alone
• Motor starter
• Soft start
• Variable speed

VersatileThe VPC™ Versatile Pump Control
system is a family of packaged rod-
pump controller solutions for sucker-
rod pumping (SRP) applications.
From simple stand-alone start/stop
control to the ultimate in variable-
speed well optimization, the VPC™
system lets you choose the appropriate
level of sophistication on a well-by-
well basis. The system is ideal for
large fields of wells of varying
maturity and requirements.
Four-in-OneEach VPC™ unit can be configured
for one of four controller types:
Stand Alone
Provides simple pump-off control
for use with a separate motor control
package.
Motor Starter
Adds an incoming circuit breaker
and a motor-starter contactor for a
single-box solution.
Soft Start
Uses a solid-state motor starter to
extend equipment life by eliminating
torque oscillations and current surges
on starting.
Variable Speed
Uses a variable-speed drive (VSD)
and patented SRP control software
to continuously optimizes production
while protecting the pumping system.
Easy UpgradeThe VPC™ system grows with your
requirements. Begin with a traditional
pump-off controller if you wish,
then upgrade to gain the advantages
of Unico’s industry-leading SRP
control. All four VPC™ versions share
a common footprint, making it easy
to convert from one controller type
to another by simply swapping panels.
A common digital-signal-processor-
based (DSP) control board and
control software minimizes spare part
requirements and operator training.
Works with Any SRPThe VPC™ system works with any
conventional, air-balanced, beam-
balanced, phased-crank, Mark II,
Reverse Mark, and Rotaflex artificial
lifts. It also works with Unico’s
innovative LRP™ linear rod pumps
and CRP™ crank rod pumps when a
compact, unobtrusive mechanical
solution is desired. The VPC™ system
operates new or existing pumping
unit motors up to 50 hp.
While not part of the modularVPC™ family, the RPC RodPump Controller offers thesame features as the Stand-Alone VPC™ controller in aneconomical package
Monitoring andReportingAll four VPC™ options
provide extensive monitoring
and reporting capabilities,
including real-time surface
and downhole dynamometer
plotting, gearbox torque
loading, daily gauging, and
more. Wireless, radio, and
cellular options allow moni-
toring at any distance. Unico’s
Web-based GMC® Enterprise
Monitoring and Control system
provides an efficient, cost-effective
tool for staying on top of daily
operations. Users can monitor
comprehensive real-time and
historical data for multiple fields
simultaneously from virtually
anywhere in the world. Units also
interface to Theta and Case
remote monitoring systems.

RobustUnits are designed to withstand the
harsh environments of the oil patch.
Weatherproof
VPC™ components are protected
inside a compact, weatherproof
NEMA 4 (IP66) enclosure and
are designed to operate in harsh
temperature extremes.
Electrical Disturbances
VPC™ units tolerate the worst of
electrical environments. They ride
through line fluctuations, high-voltage
transients, and other power distur-
bances that would normally cause
costly downtime.
Electrical Demand
Small pumping units can often be
operated using conventional motor
starters. Solid-state starters can be
used to reduce starting currents on
larger motors. Unico VSDs eliminate
inrush currents and provide near-
unity input power factor with
relatively low harmonic distortion.
SophisticatedSRP ControlUnico’s patented SRP control is
the most advanced in the industry.
The result of ten years of cumulative
development, the SRP software
offers an extensive set of features for
maximizing well production, mini-
mizing downtime, preventing
equipment damage, reducing wear,
and optimizing energy utilization.
