Running Dissimilar Pumps in
Parallel
When running pumps in parallel, it is generally agreed upon that
the pumps should be identical. However, there may be applications
or situations where it is necessary to run dissimilar pumps in
parallel. This brief article explains when running dissimilar pumps
may or maynot lead to runability issues.

VFD Pumps Can Cut Energy
Costs but Static Head Reduces Savings
This article discusses systems with various amounts of dynamic and
static head, how a system's static head effects the pump speed, and
the effect of static head on energy savings.

Proper Pump Sizing -
Selecting the proper pump is the most important step in the
development of a piping system. The pump must be sized to handle
the desired flow rate at the required pressure from the supply to
the destination. In addition, it is very important that there
is sufficient Net Positive Suction Head available (NPSHa) at the
pump suction for the pump being considered. Read more about
how you can properly size pumps based on piping system design. |

NPSH & Pump Selection:
Cavitation and NPSH Defined - Pump Net Positive
Suction Head (NPSH) is one of the most misunderstood aspects of
pump hydraulics and can be one of the most damaging. Many technical
articles and papers have been written on the subject, but little
has been written on how this damage is done. |
