HVAC Pumps
There are several types of pumps used in HVAC heating & cooling
systems, but the most common used in today is the centrifugal pump.
Types of centrifugal pumps include volute or axial flow pumps. The volute takes water
from the impeller and discharges the water perpendicular to the shaft. A centrifugal pump
with a diffuser casing (axial flow pump) discharges the water parallel to the pump shaft.
Centrifugal pumps are available in many types including circulator, single- and multi-stage
end-suction, single- and multi-stage split-case, and vertical in-line pumps.
