A standard High Hazard Set could consist of the following:
- Diesel pumpset (including pump-end, diesel engine, 6 hour single-walled fuel tank, 24v ni-cad batteries and controller within a single skid)
- Electric pumpset (including pump-end, electric motor and slide rails)
- Electric pump controller (star-delta starter with 4 volt-free contacts)
- Jockey pump (Grundfos CR pump achieves a minimum of 1 bar over the closed valve pressure of the proposed duty pump)
- Jockey pump starter (direct on-line starter)
- Remote alarm panel (for monitoring of signals remote from the pumphouse)
- Automatic supply change-over panels (used on twin electric pump installations to alternate incoming supplies to each pump)
What standards is this equipment approved / compliant to?
- LPCB – Loss Prevention Certification Board
- BSEN12845 – Fixed firefighting systems, automatic firefighting systems, design, installation and maintenance
- LPS1239 1.1 – Requirements and testing procedures for the LPCB Approval and listing of diesel engines for sprinkler pump sets
- LPS1131 1.1 – Requirements and testing Methods for pumps for automatic sprinkler installation pump sets
When would I need a High Hazard Set?
Within the UK, each building is defined by criteria of the installation and a relevant insurance body is appointed. If assigned to LPCB, then a hazard category would also be assigned. There are three of these - light hazard, ordinary hazard and high hazard and all are ranked depending on the combustibility rate of the items within the building (for instance, a high combustibility would be considered a ‘High Hazard’).
Applications
Within the UK, each building is given a designation that is defined by a number of criteria and given a hazard category. Standard categories are:
OH1
Typically: large schools and offices, hospitals, hotels, restaurants, libraries, dairies, cement works, sheet metal producers and abattoirs.
OH2
Typically: museums, bakeries, breweries, photographic labs and car workshops.
OH3
Typically: shopping centres, supermarkets, industrial processes and buildings with a highly combustible load.
HH
Typical high hazard applications are storage and distribution facilities, areas where chemicals exist and high rise buildings over 45m.
Benefits
- All products are LPCB listed and approved to BSEN12845, ensuring that they follow the correct criteria offering the peace of mind that they will work effectively.
- Extensive range of end-suction pumps available to suit requirements for fully hydraulically calculated systems giving a wider range to suit individual selection requirements.
- All pumps are tailored via impellers/orifice plates to suit the individual site requirements, reducing the maximum flow demand and ensuring the dedicated water supply tank cost is reduced.
- Pumps are engineered, built and tested in Grundfos Sunderland, ensuring the product has passed all quality checks and achieved duty parameters preventing incorrectly sized equipment reaching site.
- A wide selection of options and accessories are available including pump housing to ensure ensuring greater opportunities to select the ideal equipment.
