What Will Trigger a Jockey Pump?

A jockey pump [https://www.tkflopumps.com/multistage-fire-pump-stainless-steel-materials-jockey-pump-for-fire-product/] is a small pump used in fire protection systems to maintain pressure in the fire sprinkler system and ensure that the main fire pump operates effectively when needed. Several conditions can trigger a jockey pump to activate:

Pressure Drop: The most common trigger for a jockey pump is a drop in system pressure. This can occur due to minor leaks in the sprinkler system, valve operation, or other small water demands. When the pressure falls below a preset threshold, the jockey pump will start to restore the pressure.

System Demand: If there is a small demand for water in the system (e.g., a sprinkler head activating or a valve opening), the jockey pump may engage to compensate for the pressure loss.

Scheduled Testing: In some cases, jockey pumps may be activated during routine testing or maintenance of the fire protection system to ensure they are functioning properly.

Faulty Components: If there are issues with the main fire pump or other components of the fire protection system, the jockey pump may activate to help maintain pressure until the issue is resolved.

Temperature Changes: In some systems, temperature fluctuations can cause water to expand or contract, potentially leading to pressure changes that may trigger the jockey pump.

The jockey pump is designed to operate automatically and is typically set to turn off once the system pressure is restored to the desired level.

What Is The Purpose Of a Jockey Pump In Fire System

The purpose of a Multistage jockey pump [https://www.tkflopumps.com/multistage-fire-pump-stainless-steel-materials-jockey-pump-for-fire-product/] in a fire protection system is to maintain the pressure within the fire sprinkler system and ensure that the system is ready to respond effectively in the event of a fire. Here are the key functions of a jockey pump:

Pressure Maintenance: The jockey pump helps maintain the system pressure at a predetermined level. This is crucial for ensuring that the fire protection system is always ready to operate when needed.

Compensation for Minor Leaks: Over time, small leaks can develop in the fire sprinkler system due to wear and tear or other factors. The jockey pump compensates for these minor losses by automatically activating to restore pressure.

System Readiness:By keeping the pressure stable, the jockey pump ensures that the main fire pump does not have to operate unnecessarily for small pressure drops, which helps prolong the life of the main pump and ensures it is ready for larger demands.

Preventing False Alarms: By maintaining proper pressure, the jockey pump can help prevent false alarms that might occur due to pressure fluctuations in the system.

Automatic Operation: The jockey pump operates automatically based on pressure sensors, allowing it to respond quickly to changes in system pressure without manual intervention.

How Does a Jockey Pump Maintain Pressure?

A Centrifugal jockey pump [https://www.tkflopumps.com/multistage-fire-pump-stainless-steel-materials-jockey-pump-for-fire-product/] maintains pressure in a fire protection system by utilizing pressure sensors that continuously monitor the system's pressure levels. When the pressure drops below a predetermined threshold-often due to minor leaks, valve operations, or small water demands-the pressure sensors automatically signal the jockey pump to activate. Once engaged, the jockey pump draws water from the system's water supply and pumps it back into the fire protection system, thereby increasing the pressure. The pump continues to operate until the pressure is restored to the desired level, at which point the sensors detect the change and signal the jockey pump to shut off. This automatic cycling of the jockey pump ensures that the fire protection system remains pressurized and ready for immediate use, enhancing the reliability and effectiveness of fire safety measures.

Does a Jockey Pump Require Emergency Power?

While it is true that a jockey pump primarily operates on normal power, having a reliable power source is crucial for ensuring the pump's functionality during emergencies. Jockey pumps are designed to maintain pressure in the fire protection system, and if there is a power outage, the system may not function as intended. Therefore, while a jockey pump can operate on standard electrical power, it is often recommended to have an emergency power source, such as a generator or battery backup, to ensure that the jockey pump remains operational during critical situations. This redundancy helps guarantee that the fire protection system is always ready to respond effectively, regardless of power availability.
