Description

A Vertical Multistage Jockey Fire Fighting Water Pump, also known as a pressure-maintenance pump, is a small apparatus that works together with a fire pump as part of a fire-protection sprinkler system. It is designed to keep the pressure in the system elevated to a specific level when the system is not in use, so that the fire pump doesn’t have to run all the time and the system doesn’t go off randomly. It can also help prevent the system from damage when a fire happens and water rushes into the pipes. These devices consist of a three-part assembly. In many places, there are governmental guidelines and recommendations for installing these devices to make sure they work properly.

 

To understand how a jockey pump works, it’s important to understand how a fire sprinkler system works. Sprinkler systems consist of pipes with pressurized water in them and heads that are designed to open when they reach a certain temperature. When the heads open, the water pressure in the pipes drops, since water is flowing out of them. When this happens, a large device called a fire pump starts to send more water through the pipes so that the system can continue to put out the fire.

 

The purpose of the jockey pump is to keep the water pressure in the pipes within a specific range when there’s not a fire, so that the sprinklers won’t go off randomly. Since pipes leak, over time, the water pressure inside them automatically goes down. The jockey pump senses this, and then fills them back up to normal pressure. If a fire happens and the pressure drops dramatically, the jockey pump won’t be able to keep up, and the drop in pressure will trigger the large fire pump to start sending water.

 

Secondarily, this pump prevents sprinkler systems from being damaged when the fire pump begins sending water. If a system does not have a jockey pump keeping it pressurized, it may have a relatively low pressure. When the fire pump starts sending highly pressurized water through the pipes, the sudden change in pressure can damage or destroy the system.
