Installation manual

Carbon steel fuel tanks for storing diesel exclusively for firefighting pumps.

Manufactured in accordance with NBR-15461 and NFPA-20 standards.

Fuel tanks for diesel fire pumps from Germek Equipment are designed and manufactured to meet the main construction requirements cytomel side effects the rules NBR-15461 Storage of flammable and combustible liquids – Construction and installation of carbon steel overhead tanks and NFPA-20: Stardard for the Installation of Stationary Pumps for Fire Protection (Standards for stationary fire protection pump installations).

These locks are made of SAC 350 carbon steel in a horizontal cylindrical or vertical cylindrical format (on request) to be used exclusively for diesel motor pumps in fire prevention systems. All the tanks supplied undergo rigorous watertightness and hydrostatic resistance tests at 50KPa.

Fuel tanks for diesel fire pumps: Characteristics

Learn about the main construction features of fuel tanks for diesel motor pumps.

Fuel tanks for diesel fire pumps are intended for stationary installation, i.e. in a fixed and appropriate location, on a containment dyke (made of masonry or metal) and protected with a roof to prevent standing water from accumulating inside the containment dyke.

For safety reasons, it is recommended to install it outside the pump room, with easy access for refueling on a visible level and above the height of the diesel engine’s injection pump. The fuel tank vent must be piped to a height of 1.5 m above the roof.

In compliance with the construction requirements, fuel tanks for diesel motor pumps have some characteristics illustrated in the following figure that must be met, given each item listed its purpose and importance in the operation of the tank:


This inspection nozzle has the function of an emergency vent by means of a lid that lifts under the effect of internal pressure. This cover is fixed to the tank using long screws with threads only at their ends, to allow partial opening of its stroke. This nozzle also has the function of inspecting and gaining internal access for maintenance and cleaning.


Its function is to remove internal gases from the fuel tank (main vent). Its mushroom-shaped flame arrester must be installed at a minimum height of 1.5 m above the roof.


The tank drain consists of a 1/4″ plug and must be opened during maintenance and cleaning procedures. Its flow can be directed to the outside of the containment dyke to make it easier to remove the old diesel along with the sludge and other impurities during the cleaning procedure, which should always be carried out by specialized and trained personnel.


This nozzle consists of a ball valve that must remain LOCKED in the open position by means of a padlock to guarantee an uninterrupted supply of diesel to the engine. The valve should only be closed for tank maintenance.


The fuel return lines, as well as the supply line, must be free of any blockages, valves or barriers, to ensure the diesel runs through the motor pump. The return nozzle has a check valve to prevent backflow.


The level switch must be connected directly to the diesel motor pump’s control panel, as its function is to inform (and alarm) the panel of the volume of fuel in the tank via the float. It should be noted that the float will indicate a low fuel volume alarm when the tank is 2/3 full, meeting the regulatory requirements.


As the name implies, the filler neck should be used to fill the volume of the tank. It is similar to a car’s fuel nozzle, containing a solid pre-filter in the shape of a basket to contain large impurities.


The fuel tank also has a grounding eye that must be connected to the local plant’s grounding grid. This grounding mesh must be constructed and applied in accordance with the recommendations of NBR-5410, as well as being a mandatory safety recommendation.


The level gauge has several scales along its cylindrical shape to provide a peripheral view of the tank’s fill level. This level indicator only visually shows the volume filled. Not to be confused with the function of the level switch.

Fuel tanks for diesel fire pumps: models and capacities


The net diesel storage capacity varies according to the size of the models specified below. It should be noted that a fuel tank for a diesel fire pump must be used EXCLUSIVELY for this pump. If two diesel pumps are used in the same fire protection system, there must be two fuel tanks, one for each diesel pump.

Still on the subject of the tank’s capacity in liters, each tank must offer a minimum autonomy of 8 hours of uninterrupted operation for the diesel firefighting motor pump (according to the requirements of NBR-10897 – FIRE PROTECTION SYSTEM BY AUTOMATIC SHOWERS – Requirements), or following the criteria of NFPA-20, the proportion of 3.8 liters of diesel for every 1hp of power consumed by the diesel motor pump.
