Fire pump in India: main, diesel and jockey pumps, NBC capacities, pump room rules, testing, maintenance and cost

Fire pump IS code and key numbers at a glance

Types of fire pump: main electric, diesel standby, jockey and terrace pump

Fire pump installation in 8 steps, from sizing to handover

1. 1

   Read the Table 7 row

   Occupancy, height and floor area fix the pump set: a terrace pump, or a main, standby and jockey at the underground tank.

2. 2

   Choose the pump and motor together

   Match the pump to the motor speed; electric pumps up to 2,280 l/min usually run at 2,900 rpm as single-stage end-suction sets (IS 15301 cl. 6.2).

3. 3

   Site the pump house

   Outside the building and 6 m clear, or behind a 2 hour wall and 1 hour door on the ground floor or basement, with access from outside (cl. 4.1, 4.5).

4. 4

   Pour the foundation

   M15 reinforced concrete, 50 mm thick for pumps to 900 l/min, 75 mm to 2,280 and 100 mm to 4,500, with 150 mm spare in front and behind (cl. 6.4).

5. 5

   Lay suction and delivery

   An independent suction for each pump, one connection from each tank compartment, a pressure gauge before the non-return valve and a test line (cl. 6.6, 6.8, 6.11).

6. 6

   Wire the panels

   Floor-mounted panel with auto-manual switch, pressure switches on an air vessel, a separate diesel panel interlocked with it, and a supply taken before the main LT breaker (cl. 5.2 to 5.4, 6.15).

7. 7

   Test and record

   Record flow at 7 kgf/cm², flow at 4.5 kgf/cm² and the gauge at 120 percent of 7 kgf/cm² in the pump house register (cl. 7.2.1).

8. 8

   Fire officer's inspection

   The officer runs the pumps on site against the approved plan before the final fire NOC; in Maharashtra the licensed agency signs Form A for the building.

Fire pump room parts name: 12 items in a pump house

IS 15301 defines the parts of a fire pump installation in clause 3 and places them in clauses 5 and 6.

SStatic water tank

Underground or surface tank that stores water for fire fighting only (cl. 3.1). 1IS 15301:2003

TTerrace tank

Concrete, masonry, plastic or steel tank on the roof that feeds the terrace pump (cl. 3.2). 1IS 15301:2003

MMain fire pump

Electric or diesel pump at the static tank that charges the wet riser or sprinklers (cl. 3.7). 1IS 15301:2003

SStandby pump

Pump of the same capacity on a diesel engine or another power source (cl. 3.8). 1IS 15301:2003

JJockey pump

Small pump that starts on a drop in static pressure and stops when the preset pressure is back (cl. 3.5). 1IS 15301:2003

PPump panel

Panel with the starting, stopping and indicating devices, floor mounted and compartmentalised, with a copper busbar and 1.8 mm sheet (cl. 3.9, 5.2). 1IS 15301:2003

PPressure switch

Switch on the delivery line or air vessel that starts the main or jockey pump when pressure falls below its setting (cl. 3.10). 1IS 15301:2003

AAir vessel

Pressure vessel in the pump house carrying the two pressure switches (cl. 5.4). 1IS 15301:2003

PPriming tank

Small tank above the pumps that keeps the casing and suction full where the pump lifts water (cl. 3.3). 1IS 15301:2003

FFoot valve and strainer

Inward-opening valve at the suction strainer for a lifting pump; a plain strainer on flooded suction (cl. 3.4). 1IS 15301:2003

CCirculation relief valve

Opens below shut-off pressure to circulate about 3 to 5 percent of rated flow so a pump on closed delivery does not overheat (cl. 3.11, 6.11). 1IS 15301:2003

TTest line

Line and shut-off valve on each pump to test it without discharging into the system (cl. 6.11). 1IS 15301:2003

How a fire pump and jockey pump work: the pressure sequence

The system sits charged and still. Each pump starts on its own falling pressure, and only a person can stop the main pump.

Fire pump capacity as per NBC 2016 Table 7, by building

Table 7's notes name the pump set for each row: a terrace pump for low buildings, then electric and diesel pumps with a 180 l/min jockey. These rows were read off the printed pages.

Note 12's pump set is 2,850 l/min with a 180 l/min jockey. The 1,620 l/min size in Note 14 is not one of IS 15301's listed sizes; the Table 7 note governs where the state applies the code. Rows not shown are on the NBC 2016 page.

Fire pump performance numbers: flow, head and shut-off

Six figures from IS 15301 decide whether a pump is fit for fire duty and how it is tested at handover.

• 150 percent

  Of rated flow at which the pump must still give more than 65 percent of rated head (cl. 6.7) 1IS 15301:2003

• 120 percent

  Most a horizontal pump's shut-off head may be of its rated head; 140 for vertical turbine (cl. 6.7) 1IS 15301:2003

• 180 l/min

  Smallest jockey pump allowed, within 3 to 10 percent of installed capacity (cl. 6.5) 1IS 15301:2003

• 7 kgf/cm²

  Pressure at which commissioning flow is recorded, again at 4.5 kgf/cm² (cl. 7.2.1) 1IS 15301:2003

• 2,900 rpm

  Usual motor speed for electric fire pumps up to 2,280 l/min (cl. 6.2) 1IS 15301:2003

• 20 percent

  Margin a sprinkler pump must exceed the calculated flow and pressure by (IS 15105 cl. 12.1(e)) 3BIS, IS 15105:2021

Fire pump room design rules from IS 15301 and IS 3844

Clauses 4 to 6 of IS 15301 and clause 4.2 of IS 3844 fix where the pump room goes and how it is built. Inspectors check these first.

Diesel fire pump: engine, panel, battery and fuel rules

The diesel standby is what keeps water on a fire when the grid fails. IS 15301 and Maharashtra's guidelines set four rules for it.

• cl. 5.3

  Its own panel and battery

  A separate panel in the pump room or the room next door, with its own battery, battery charger and auto-manual changeover. 1IS 15301:2003

• cl. 5.3, 5.5

  Interlocked, self-starting

  Interlocked with the main panel so electric and diesel pumps do not run together, and started by its own low-pressure switch. 1IS 15301:2003

• cl. 7.3.2

  Fuel for 4 hours

  Enough fuel of the right grade for 4 hours of running without refilling, checked weekly, with the sludge trap and battery. IS 15301 gives no tank size in litres. 1IS 15301:2003

• MFS guidelines

  Day tank checked at commissioning

  Maharashtra's July 2026 Form B guidelines ask the engine to run 10 minutes with fuel in the day tank for 4 hours of running. 6MFS Form B guidelines

Fire pump testing and commissioning checklist

IS 15301 asks for the handover test to be written into a register kept in the pump house. These are the points to record.

Fire pump maintenance checklist: daily, weekly and yearly

IS 15301 clause 7.3 sets the daily and weekly routine and names a responsible person to keep it (cl. 7.1).

1. Daily

   Open a valve slightly and time how long the jockey pump takes to restore pressure. 1IS 15301:2003

2. Daily

   Run the main pump for at least 5 minutes, started by letting pressure fall, and check glands and packing. 1IS 15301:2003

3. Weekly

   Grease bearings, clean starter contacts and measure the motor circuit's insulation resistance. 1IS 15301:2003

4. Weekly

   Start the diesel by cutting the power and letting pressure fall, run it 10 minutes, check fuel for 4 hours, the sludge trap and the battery. 1IS 15301:2003

5. Weekly

   Check alignment, nuts, bolts and coupling guard after 15 minutes of continuous running. 1IS 15301:2003

6. Every 6 months

   Measure pump motor insulation as part of the sprinkler system's 6-monthly checks (IS 15105 cl. 15.6.4(c)). 3BIS, IS 15105:2021

Fire pump faults that hold up a fire NOC

Each fault below breaks a clause of IS 15301 or IS 3844 that a fire officer can see in the pump room.

Fire pump myths the codes contradict

Four claims owners repeat about fire pumps that the codes do not support.

• You may have read

  The jockey pump is a small fire pump that fights the fire.

  Myth

  What the sources say

  It only makes up leaks between its two pressure limits; the main pump does the fire duty (IS 15301 cl. 3.5, 5.4). 1IS 15301:2003

• You may have read

  A pump that gives its rated flow is good enough.

  Myth

  What the sources say

  It must also give more than 65 percent of rated head at 150 percent of rated flow, and keep its shut-off head within 120 percent (cl. 6.7). 1IS 15301:2003

• You may have read

  The diesel pump can be smaller than the electric one.

  Myth

  What the sources say

  The standby pump is of the same capacity as the fire pump (cl. 3.8). 1IS 15301:2003

• You may have read

  IS 3844 and IS 15301 agree on the priming tank.

  Myth

  What the sources say

  IS 15301 asks at least 3 times the suction pipe and casing volume (cl. 6.10); IS 3844 asks 8 times the suction pipe volume (cl. 4.2.4). Use the larger unless your approval says otherwise. 1IS 15301:2003

Fire pump set for 3 buildings: worked examples

Flamekite's reading of Table 7 and IS 15301 in states that name NBC 2016. Your fire service's reading prevails.

1. Case 1

   A 20 m block of flats

   Group A-4, ground plus 6, top floor 20 m.

   What applies The 15 m to 35 m row: a 900 l/min terrace pump on a 25,000 litre terrace tank feeding a down-comer. No pump house at ground level until the building passes 35 m. 4NBC 2016, Table 7

2. Case 2

   A 22 m office building

   Group E business, 22 m, no basement.

   What applies Note 10: one 2,280 l/min electric pump, one 2,280 l/min diesel standby and a 180 l/min jockey on a 1,00,000 litre underground tank. 180 l/min is about 4 percent of the 4,560 l/min installed, inside IS 15301's 3 to 10 percent band. 8NBC 2016, Table 7

3. Case 3

   A 1,500 m² moderate hazard factory

   Group G-2, one storey.

   What applies Note 11: two electric pumps and one diesel pump of 2,280 l/min with a 180 l/min jockey, on a 1,50,000 litre underground tank. 10BIS, NBC 2016 Part 4

Which rule sets your fire pump: NBC, IS 15105 or the state

IS 15301 says how to install and keep a pump; the building rule your state applies says which pumps you need.

1. IfYour state names NBC 2016 in its fire law

   Table 7's row and its pump note set the pump set; IS 15301 governs how it is installed and kept. NBC 2016 4NBC 2016, Table 7

2. IfYour sprinkler hazard is not covered by Table 7

   IS 15105:2021 sizes sprinkler pumps and storage, with 30, 60 or 120 minutes of pump running by hazard (Table 30). IS 15105 3BIS, IS 15105:2021

3. IfYour building is in Maharashtra

   Schedule-I of the 2006 Act sets the pump sets by row; a licensed agency installs and certifies them. Fire NOC Maharashtra 11MH Act 2023 Schedule-I

4. IfYour building is in Assam, or a UP workplace of 5+ floors or 20 m+

   NBCS 2026 Part F applies through the Assam fire Act or rule 12 of the UP OSH Rules 2026. NBC 2026 12UP Gazette

5. IfYour building is very tall

   NBC 2016 Annex E asks intermediate tanks and pumps at 160 to 180 m once a building passes 150 to 175 m. High Rise Building Height as per NBC 13NBC 2016, Annex E
