CPP understands pumps used in HVAC and provide customized solutions of pumps, pump sets and factory-assembly system.
Close coupled single suction pumps | motor and pump cannot be misaligned with each other physical space requirements less than those required by the flexibly coupled single suction pump |
Flexibly coupled single suction pumps | uses a standard motor and less expensive than the close-coupled pump in large motor size |
Vertical mount end suction pump | save equipment room floor space able to rotate the discharge to accommodate the discharge piping |
In-line end suction pump | can be inserted directly in a pipeline and save considerable floor space |
Self-priming pump | Typical applications are chiller sumps and open energy storage tanks such as are used in cold water or ice storage systems |
Double-suction pumps | by far the preference of most designers when the flow in a water system exceeds 1000 gal/min, and considering its easy maintenance |
Turbine pumps | usually found in HVAC applications |
Mixed-flow pumps | found in the HVAC industry on large cooling tower pump installations |
Axial-flow pumps | used in cooling tower service with capacities in excess of 500 gal/min |
Small multistage turbine pumps | applied in the HVAC field on low-flow, high-head applications such as feeding high-pressure boilers |
Positive-displacement pumps | small in size |
About Factory-Assembled Pumping Systems
Advantages
Low Cost. Offers the lowest-cost procedure for designing, building, and installing a pumping system for most new installations.
Time saving. Offer savings in time during design, construction, and installation.
Unit responsibility. Only one company to deal with in solving problems and getting the pumping system to operate as specified.
Less pump maintenance and repair. Properly designed pumping system instead of mounting the pump in the field has been proved by years of operation in the field.
Typical system arrangements
for chilled water in sizes from the simple primary pumping system
large variable-speed secondary pumping system
Pumping system with expansion tank and heat exchanger
Pumping system with vertically mounted double-suction pumps
Primary-secondary pumping systems
