A jockey pump is a small pump connected to a fire sprinkler system and is intended to maintain pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause a pressure drop which will be sensed by the fire pump automatic controller, causing the fire pump to start. The jockey pump is essentially a portion of the fire pump's control system.

What type of pump used for water mist system?
it uses centrifugal pump type to maintain pressure of 120 kg/cm2
What is gear type pump?
A gear type pump has two gears in it that pull fluid through between the teeth creating pressure as it is forced out the other side.
Will a faulty check vavle cause the pump to lose its prime?
Yes it could. It would depend on it's application, where it is in relation to the pump and the type of pump and system you have.
What is centrifugal coupled pump?
You may mean a "close-coupled pump" in which case, that is a pump which is mounted directly on the same shaft as the driving motor: i.e. there is no baseplate or coupling to join the two shafts, drive and driven, and the pump hangs off the notor frame. A centrifugal pump is a type of pump where the liquid is forced to travel by an impeller which is inside a close-fitting chamber, or "volute" - it is probably the most common industrial and domestic pump type.
What are the type of pumps used for ballast and bilge?
Manual ballast water/bilge pumps are often diaphragm pumps with flapper valves. Large pumps are often positive displacement, centrifugal or moving cavity pumps depending on the amount of crud expected in the ballast.
Jockey pump capacity how related with main fire pump capacity?
5 hp
What is the function of the pump?
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.
Can you be a jockey if you have type 1 diabetes?
Of course. With type 1 diabetes, you can still do anything.

What is the wage for a disc jockey?
Most disc jockeys make between $5,000 and $40,000. The exact amount depends on the type of disc jockey, the disc jockeys popularity, the location of the disc jockey, type of payment, and whether the disc jockey is a hobbyist. For instance, a mobile disc jockey may be paid $800 for one performance, but they may only perform twice a month. Meanwhile, a club disc jockey may be paid $10/hour but with a full time position, the club disc jockey would be making just as much as a mobile disc jockey without including tips. Also take into account that a mobile disc jockey has expenses that a club disc jockey doesn't and you'll see that the club disc jockey in my example actually make more that the mobile disc jockey.

What is the function of the fire and jockey pump?
A jockey pump, or 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.How it WorksTo 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 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.AssemblyAll jockey pumps consist of a pump, a motor, and a controller. The two main types of pumps available are centrifugal and regenerative turbine pumps. Both have their pros and cons: the centrifugal type is often less energy-efficient, but it needs less maintenance than a regenerative turbine one. Likewise, a regenerative turbine pump can create a lot of pressure with very little power, but it can make the system too pressurized, and needs a lot of maintenance. Which type is best for a system also depends on the size of the system, with centrifugal pumps often being preferred for smaller systems, since they sometimes create less pressure.The type of motor used also depends largely on the size of the system. The two main choices for jockey pump motors are single-phase and three-phase. Both work largely the same way, though single phase motors are typically used for smaller, lower pressure systems since they're not as powerful. Controllers can also be either single-phase or three-phase, and differ primarily in the complexity of their assembly.RequirementsMany places have governmental standards for installing and maintaining jockey pumps. In the US, the National Fire Protection Association's (NFPA) guidelines are the standard. These include things such as the recommended power for a jockey pump in relation to a system's size, how long it can take to repressurize the system, and the pressure that it needs to maintain.
