TEAM UP!
FOR FAN AND PUMP SAVINGS
It can be as easy as
replacing an old drive belt.
Why should we care?
 For the environment
 For the bottom line
Why should we care?
 For the environment
 Replacing a worn-out
drive belt can drive big
environmental gains.
Why should we care?
 For the bottom line
 Installing variable
speed drives can
result
in energy savings of
40 to 60 percent.
Fans and Pumps
 Fans provide the motive force to
move air against the resistance of
an air-conveying system.
 Pumps provide the motive force
to move liquids against the
resistance of a piping system and
against changes in elevation.
 Both use electric motors and
drives.
What can we do?
1. Housekeeping
2. Low-cost
opportunities
3. Retrofits
What can we do?
1. Housekeeping






Inspect and maintain fans and pumps.
Check and adjust belt drives regularly.
Correct excess fan noise and vibration.
Clean and lubricate fan components.
Clean or replace air filters regularly.
Clean ductwork, and fix duct and
component leaks.
What can we do?
1. Housekeeping



(cont.)
Clean pump impellers, and repair
or replace if eroded or pitted.
Maintain clearance tolerances at
pump impellers and seals.
Shut down fans and pumps when
not needed.
What can we do?
2. Low-cost opportunities


Streamline air-duct connections to
reduce losses.
Optimize airflow, by balancing
dampers in their maximum open
positions for balanced air distribution.
What can we do?
2. Low-cost opportunities


(cont.)
Replace packing-gland pump
seals
with mechanical seals, which
require far less pump power.
Trim the pump impeller to match
system flow rate and head
requirements.
What can we do?
3. Retrofits


Add variable speed motors
and drives so the flow of air
or water can be adjusted to
changing requirements.
Replace outdated units with
more efficient and correctly
sized equipment.
What can we do?
3. Retrofits


(cont.)
Decentralize a major system
into sub-systems that serve
their own specific
requirements.
Control the ventilation system
with ultrasonic occupancy
sensors – this saved one
manufacturer 50 percent in fan
operating costs.
What can we do?
3. Retrofits


(cont.)
Install a computerized energy
management control system.
Install variable voltage, variable
frequency inverters to allow motor
speed to be continuously varied to
meet load demand – power savings
range from 30 to 60 percent.
How can we do it?
We have the people.
We have the tools.

Thank you
Together we can make it
happen.
It’s good for the environment.
It’s good for the bottom line.
