Final answer:
Pressure Maintenance Pumps are commonly called Jockey Pumps, which are used to maintain constant system pressure in applications like fire sprinkler systems. Option 1.
Step-by-step explanation:
Pressure Maintenance Pumps are also known as Jockey Pumps. These pumps are often used in water pressure booster systems, including fire sprinkler systems, to maintain a constant set pressure in the system. When the system pressure drops due to a leak or when a fire sprinkler is activated, the jockey pump starts to operate, maintaining pressure without having to activate the main fire pump, which is often much larger and designed for emergency use only.
Pressure Maintenance Pumps, also known as Jockey Pumps, are a type of centrifugal pump used to maintain pressure in a water-based fire protection system. They are typically connected to a fire pump system and are designed to run at lower pressures and flow rates compared to the main fire pump. Jockey pumps are responsible for maintaining the system pressure within a specific range by adding or removing water as needed.
