BRISTOL packaged fire pump sets are complete systems engineered on a single skid: main fire pumps, jockey pump, controllers, all accessories and piping, from a single pump to multi-pump systems. The skid is designed from load calculations with lifting points set by the centre of gravity. It is installed in the pump room; on site only power and pipe connections are made. See the fire pump room valves guide.
In short
- All equipment and piping on one skid with lifting points.
- Layout designed for easy access to every instrument and valve.
- Flow up to 5500 GPM; pressure 40 to 200 m.
- UL/FM listed range: up to 3000 GPM.
- Engineered and built to NFPA 20, and factory tested.
- On site, only power and pipe connections are made.
What the set contains
Typical scope of supply: UL/FM main pump (split case or end suction) with electric and diesel drive, jockey pump, electric, diesel and jockey controllers, suction and discharge gauges, air release and casing relief valves, piping with valves for suction, discharge, test line and PRV, check, butterfly and OS&Y gate valves, SS 304 pressure sensing line, and flow meter.
Compared with site assembly: alignment, piping and wiring are done and tested at the factory, reducing site work and errors and giving single-source responsibility.

The critical point: room space and access route
The set arrives in one piece, so check its dimensions against the pump room door, access route and maintenance clearances before approving drawings.
The scope of supply is confirmed per project.
General design notes on selecting a fire pump
- Rating point: the pump is selected so its rated flow and pressure cover the system demand from the hydraulic calculation.
- Curve shape in NFPA 20: shut-off (no flow) pressure does not exceed 140% of rated pressure, and at 150% of rated flow the pressure is not less than 65% of rated.
- Horizontal pumps need positive suction (water source above the pump). Where the source is below the pump, a vertical turbine pump is used.
- A jockey pump makes up small leaks and holds system pressure, so the main pump starts only on real demand.
- Driver type (electric or diesel) and the number of standby pumps depend on the reliability of the power supply and the authority’s requirements.
- Shut-off pressure plus suction pressure must not exceed the pressure rating of system components; otherwise reselect or manage the pressure per the standard.
General engineering notes
These points are general principles from NFPA 20, NFPA 25 and common design practice, not from the BRISTOL catalogue. Final pump selection is made by the project’s approved designer from the hydraulic calculation and the requirements of the authority having jurisdiction.
Installation steps
- Send the project specification: flow, pressure, number of pumps, driver types and site space.
- Review and approve the package drawings before fabrication.
- Prepare the foundation and connection points (suction, discharge, power, drains).
- Lift by the designated lifting points and connect piping and power.
- Run the field acceptance test.
Common mistakes
- Ordering without stating the site space and access route.
- Assuming every scope item is included: the scope of supply is confirmed per project.
- Overlooking diesel engine ventilation and exhaust.
Inspection and maintenance
Per NFPA 25, the fire pump is run periodically at no flow to confirm readiness, and an annual flow test measures the curve points (no flow, rated flow and 150% of rated) against the factory curve.
Inspection, testing and maintenance are the owner’s responsibility per NFPA 25, preferably by a qualified company. Notify the owner, the monitoring station and everyone affected before any test.
Files and ordering
The BRISTOL fire pumps catalogue (with the selection charts and dimensions) is in the files section of this page. For a quotation, state the required flow (GPM), required pressure (psi or bar), driver type (electric or diesel), and whether UL or FM is required, plus the number of pumps and site space.
How to order
Use the “Build your order” section on this page: add every model and quantity, then send the whole order by email or WhatsApp. It reaches us as a tidy PDF request sheet and we contact you with the quotation.
FAQ
How does it differ from the containerized set?
This is an open skid installed in an existing pump room. The containerized set brings its own enclosure.
Does it include the jockey pump and controllers?
Yes within the typical scope, confirmed in the quotation.
