Pump packs, also known as pump groups or pump sets, are essential components in HVAC and industrial installations. They circulate fluids such as chilled water, hot water, or refrigerants through the system to ensure efficient heat exchange and temperature control.
Clivet, as a top HVAC solutions provider, integrates various types of pump packs into their systems to maximize performance, reliability, and energy efficiency.
Single Pump Pack
Description
- Contains a single pump unit, usually a centrifugal pump.
- Simple and cost-effective solution for small to medium systems.
- Often used in residential or light commercial HVAC setups.
Advantages
- Easy installation and maintenance.
- Lower initial cost.
- Suitable for systems with lower flow and pressure requirements.
Typical Clivet Applications
- Small hydronic heating or cooling circuits.
- Simple chilled water loops in Clivet modular chillers.
Dual Pump Pack (Primary-Secondary Pumping)
Description
- Includes two pumps arranged either in parallel or series.
- Commonly configured as a primary-secondary system to separate the primary loop (chiller side) from the secondary loop (distribution side).
- Ensures stable flow and hydraulic separation.
Advantages
- Enhanced system stability and control.
- Redundancy ensures reliability in critical systems.
- Optimizes energy consumption by running pumps according to demand.
Typical Clivet Applications
- Medium to large commercial HVAC systems.
- Clivet modular chillers and large VRF installations.
Variable Speed Pump Pack
Description
- Equipped with a pump that operates at variable speeds, controlled by a variable frequency drive (VFD).
- Adjusts flow rate dynamically based on load requirements.
- Provides energy savings by reducing power consumption during partial loads.
Advantages
- High energy efficiency.
- Improved system control and comfort.
- Reduced wear and longer pump life.
Typical Clivet Applications
- Advanced hydronic systems.
- High-efficiency chillers and VRF systems with varying load demands.
Booster Pump Pack
Description
- Specialized pump pack designed to increase pressure in the system.
- Used when supply pressure is insufficient or for systems with high static head.
Advantages
- Ensures proper flow and pressure to all system components.
- Can be installed as standalone or in combination with main pump packs.
Typical Clivet Applications
- Tall buildings or extended piping networks.
- Systems requiring pressure boosting to maintain performance.
Multi-Pump Pack (Pumped in Parallel)
Description
- Contains multiple pumps working in parallel to meet variable flow and pressure demands.
- Pumps can be staged on/off based on load conditions.
Advantages
- Scalability and redundancy.
- Energy savings through selective operation.
- High capacity for large installations.
Typical Clivet Applications
- Large commercial and industrial HVAC plants.
- Complex chilled water or heating systems.
