E-Flo® DC

Dual Control Electric Circulating Pumps

Constant pressure when you want it. Constant flow when you need it.

Single Pump. Dual Control.

E-Flo DC

Get the benefits of a pneumatic motor with the energy

efficiency of an electric drive unit!

Our new Dual Control (DC) E-Flo pumps allow the

pump to operate two different ways – constant

pressure or constant flow rate.

Tap into the energy savings and advanced features of
an electric pump. It’s easier than you think to make the switch.

Save Energy

5x More Efficient

Electric motor means big savings when compared to similar­sized pneumatic motors – helping lower your energy bill and
saving you money.

Outperform

Gain More Control

Advanced Control Module allows you to easily integrate the
pump into a PLC network for even greater control and visibility.

Improve Quality

Dual Control (DC) technology gives you less pulsation
and smooth, rapid changeovers – for better, more
consistent finishes.

Changeover Comparison

Improve Productivity

Spend Less Time Training

Electric pump functionality, with the simplicity of a pneumatic
pump, makes it easy for anyone to operate.

Stay Up and Running Longer

Increased reliability means you’ll spend less time maintaining
and more time up and running.

Better Working Environment

Quiet electric motor means happier operators and better results.
Exceeds OSHA sound regulations and over 20 dbA’s quieter
compared to similar-sized pneumatic motors.

Boost Your Profits

Prevent Material Loss

Integrated runaway protection protects your pump from
premature wear and prevents costly material loss.

Eliminate Costly Rework

Electric motor eliminates icing – giving you smoother pump
operation and better finished product.

Lower Cost of Ownership

Use less energy and spend less on maintenance costs with
the field-proven reliability of Graco’s 4-ball pump.

Boost Your Bottom Line

with Energy Savings and Advanced Pump Control

Advanced Motor with Control Module

Efficient and smart, the E-Flo DC with Advanced Control
Module gives you additional control of pump performance and
allows you to manage several pumps from a single module.

Multiple Pump
Networking

Control several pumps
from a single control
module

Simple to Install

Basic installation requires
only a single-phase *110/220 V,
50/60 Hz power

No VFD’s Required.

* 110 V power available with 1HP motor only.

4

Control Module

• Integrate the pump easily into a PLC Network for better visibility

and control outside of the hazardous area

• Configure different operating profiles of pump

• Mount directly on pump motor or remotely on nearby wall

• Up to two pressure transducers can be added for greater control

• Connect pneumatic BPR controller to automate an “off-production” profile

for even greater energy savings

• Password protect pump settings to protect against unauthorized access

4-Ball Lower

Graco is making it easier to install,

upgrade and maintain your 4-ball pump.

Not only can our lowers be used with
pneumatic, hydraulic or electric platforms,
many models have common components
– making it easier to upgrade existing
equipment and stock replacement parts.

Basic Motor

Operator-friendly control knobs have clear symbols making it easy
to adjust pump settings. Gives you local control at the pump and
runaway protection.

Enclosed Wet Cup

Maintain consistent lubrication for
packings, reducing maintenance time.

Spring Loaded Packings

Increases the life of throat packings

Consistent torque – no operator needed
to make adjustments

Improved Coating Options

Standard Chromex™ Rods for added durability

Available MaxLife

How to Select Your E-Flo DC

STEP

Pump Selections

1

Refer to the Pump Selection Table on the next page to answer the following questions:

Lower Size – Based on desired pressure and flow rates, what size lower is required? 750 cc, 1000 cc, 1500 cc or 2000 cc

Motor Size & Controls – What motor size and control type would you like on the motor? 1 or 2 hp, Basic or Advanced

Lower Fittings – What lower material and type of fitting is required on the lower?

Hard Chrome/NPT, Hard Chrome/Tri-Clamp or MaxLife/Tri-Clamp

Mount – How would you like to mount the pump? Stand Mount, Wall Mount Bracket or None

If Basic motor control is desired, your pump selection is complete.
Refer to the Pump Selection Table on the next page for your part number.

If Advanced motor control is desired, determine the desired mounting
location of the Control Module. The Control Module can be mounted directly on
the pump or on a nearby wall. Select the appropriate CAN cable length.

NOTE: Up to 8 pumps can be controlled from a single Control Module. In this
application, the pump electronics will be daisy-chained together via CAN cable.
Select the appropriate CAN cable length.
