Methodology
A system analysis requires an on site visit to evaluate
the current operational status of the existing pumping system, including a review of the following items:
- original design specifications
& performance/operating parameters
- past history of known system
deficiencies
- maintenance
history
Most important is ensuring a complete understanding and
agreement of the client’s desired future goals and expectations for a replacement/rerated/upgraded system.
The following performance parameters will be
measured:
- pump suction and discharge
pressures
- downstream of any throttling or
control valves, if installed
- actual flow measured, utilizing
a clamp on, ultrasonic flow meter
- motor amps
- RPM for variable speed
applications
- data logging both flow &
amps over a given time period for varying flow applications
Verifying the actual flows, pressures and amp draw on
an existing system is the only way to confirm pump performance, system requirements and energy costs over an operational time period and/or to select the best upgrade/replacement options for the
future.
End Product
The gathered data will be
analyzed and presented in a detailed report with the following information:
- purpose or end goal for
project/study
- summary of system
description
- summary of existing range of
performance parameters (flow, pressures, amps)
- existing pump/system curve with
min/max, normal operating values
- recommended new pump/system
curve with min/max, normal operating values
- economic analysis comparing
existing system to recommended upgrade/ replacement option(s), including estimated installed cost and operating costs
