Overview
E-Flo Pump Operational Overview
An electric motor (B) provides input to a 75:1 gear reducer (GR), which drives two fluid pumps (FP). See FIG. 1. The
stroke positions of the two pumps are offset to achieve consistent flow from the pump assembly. See F
The optional sensor circuit includes a top dead center (TDC) sensor to measure motor speed, a position sensor (PS)
to measure motor position, and a pressure transducer (PT) to measure fluid pressure at the pump outlet. The Graco
ACS control module software mimics the effect of a camshaft, constantly adjusting motor speed to keep steady fluid
flow and achieve minimal pressure variation. The output shaft of the gearbox and the connecting rods experience the
electrical control module simulating the function of a camshaft by speeding up when the pressure drops (pump lower
is at a changeover) and slowing down when pressure increases (both lowers are pumping).
The ACS module provides an analog drive signal to the VFD. Use one ACS module for each E-Flo pump. The ACS
module can be controlled by a local control box mounted in the hazardous area, or via communication protocol (such
as modbus).

following key VFD settings:
• analog input scaling
• 4 mA = 0 (zero) Hz
• 20 mA = 80 Hz
• Acceleration rate = 1.0 sec (for full range 0-80 Hz)
• Deceleration rate = 0.5 sec (for full range 0-80 Hz)
NOTE: If the ACS is used with an E-Flo 1500 pump and
a 3 HP motor, activating the VFD slip compensation feature may reduce motor heat and improve performance
under certain conditions.

Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty
installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of
non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of Graco equipment with
structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or
maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of
the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned
to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs
will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy
(including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or
consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.
