Jockey Pump vs Main Fire Pump – Complete Difference, Functions and Uses Guide

# Jockey Pump vs Main Fire Pump – Complete Difference, Functions and Uses Guide

A fire protection system depends on reliable water pressure to operate effectively during emergencies.

Two important components used in fire pump systems are:

• Jockey Pump
• Main Fire Pump

Although both pumps are part of the same fire protection system, their functions are completely different.

A jockey pump maintains normal pipeline pressure, while the main fire pump provides the high-volume water supply required during an actual fire emergency.

Understanding the difference between these pumps helps building owners, facility managers and safety professionals maintain effective fire protection systems.

Fire pump systems are commonly installed in:

• Factories
• Warehouses
• Hospitals
• Hotels
• Apartments
• Commercial Buildings
• Industrial Facilities

Sri Pondy Fire and Safety provides fire pump installation, testing, maintenance and complete fire protection solutions for industrial and commercial buildings.

# What Is a Jockey Pump?

A jockey pump is a small pressure maintenance pump installed in a fire protection system.

Its main purpose is to maintain the normal pressure inside fire protection pipelines when there is no fire emergency.

A jockey pump does not provide firefighting water during a fire.

It only compensates for small pressure losses caused by:

• Minor Leakage
• Temperature Changes
• Normal Pressure Reduction

---

# Functions of a Jockey Pump

The main functions of a jockey pump include:

1. Maintaining System Pressure

The jockey pump keeps the fire protection pipeline pressurized and ready for emergency operation.

---

2. Preventing Unnecessary Main Pump Starting

Small pressure drops are handled by the jockey pump instead of starting the large main fire pump.

This helps:

• Reduce Wear
• Save Energy
• Increase Pump Life

---

3. Maintaining System Readiness

A pressurized system ensures that:

• Hydrant Systems
• Sprinkler Systems

remain ready for immediate operation.

---

# What Is a Main Fire Pump?

A main fire pump is the primary firefighting pump designed to provide high-pressure water flow during an actual fire emergency.

It supplies water to:

• Fire Hydrant Systems
• Fire Sprinkler Systems
• Fire Fighting Equipment

The main fire pump operates when a large amount of water is required.

---

# Functions of Main Fire Pump

1. Providing Firefighting Water Supply

The main fire pump delivers high-volume water flow to control fires.

---

2. Maintaining Required Pressure

It provides the pressure needed for:

• Fire Hoses
• Sprinklers
• Hydrant Valves

---

3. Supporting Emergency Response

The main pump ensures firefighters have continuous water supply during fire operations.

---

# How Jockey Pump and Main Fire Pump Work Together

Both pumps work as a team to maintain fire protection system reliability.

The working sequence is:

Normal Condition

• Pipeline pressure is maintained.
• Jockey pump handles minor pressure drops.
• Main fire pump remains standby.

---

Small Pressure Loss

Example:

• Minor leakage
• Temperature-related pressure changes

Process:

1. Pressure decreases slightly.
2. Jockey pump starts.
3. Pressure returns to normal.
4. Jockey pump stops.

---

Fire Emergency Condition

When a fire occurs:

1. Sprinkler opens or hydrant valve is operated.
2. Large amount of water flows.
3. Pipeline pressure drops significantly.
4. Jockey pump cannot maintain pressure.
5. Main fire pump starts automatically.
6. Continuous firefighting water supply begins.

---

# Jockey Pump vs Main Fire Pump Difference

| Feature | Jockey Pump | Main Fire Pump |
|---|---|---|
| Main Purpose | Maintain Pressure | Fight Fire |
| Size | Small | Large |
| Water Flow | Low Flow | High Flow |
| Operation | Frequent Small Adjustments | Emergency Operation |
| Firefighting Capability | No | Yes |
| Power Requirement | Low | High |
| Pressure Maintenance | Normal Condition | Fire Condition |
| Cost | Lower | Higher |
| Usage | Daily Pressure Control | Emergency Response |

# Jockey Pump Working Principle

A jockey pump works automatically based on pressure changes.

Process:

1. Fire protection pipeline remains pressurized.
2. Pressure drops slightly.
3. Pressure switch detects the drop.
4. Jockey pump starts.
5. Pressure returns to normal.
6. Pump stops automatically.

---

# Main Fire Pump Working Principle

The main fire pump activates when there is a major pressure drop.

Process:

1. Fire protection equipment demands water.
2. Pipeline pressure decreases.
3. Pressure switch activates.
4. Main fire pump starts.
5. High-pressure water is supplied.
6. Firefighting operation continues.
