I am a designer for electrical and mechanical systems. Where can I find technical articles on the subject of emergency generators?
Most generator manufacturers maintain websites with comprehensive application and installation guides for their products. You may also visit On-Site Power Advisor for helpful information and design support related to emergency generator ancillary equipment, such as fuel systems, exhaust systems, etc.

Per NFPA 110: “Fuel tanks shall be close enough to the prime mover for the fuel lift (suction head) of the prime mover fuel pump to meet the fuel system requirements, or a fuel transfer pump and day tank shall be provided.”
How can we locate a fuel leak in a piping system without major excavation or complete pipe replacement?
Locating a leak in secondary containment piping is difficult to do in below-ground piping systems, where leaks are collected in a low-point sump. For existing sites, contact your local DEP Division for a referral to an organization that can perform leak location services. For new designs, you may consider a continuous leak monitoring system to pinpoint the exact location of a leak, should it ever develop.

You need a Fuel Fill Station. This article should help you select the right one.
You should consider a Fuel Port with a built-in fuel transfer pump. The Simplex SmartPump is designed to transfer fuel from a fuel delivery truck to one or more remote storage tanks. This On-Site Power Advisor article may be helpful.
You can rely on Simplex to select the pump and motor combination to meet the required flow rate for your project. To do so, Simplex will need the flow rate (GPM or GPH), the specified total dynamic head (TDH) for the fuel piping, and the preferred system voltage. But if you would like to do some of your own calculations, this Pump Selector is very useful. When providing the input variables, try using the following:
Construction: Cast Iron
Sealing Options: Mechanical Seal
Differential Pressure: as needed
Specific Gravity: 0.85
Flow Rate: as needed
Max RPM: 1750
When you are presented with pump selections, look for “SG Series” pumps. Also good to know: the 1800 rpm pumps (with 1800rpm motors) are less expensive. The slower-speed 1200rpm pumps are quieter but require more expensive motors.
Once you have arrived at your selection, don’t forget to read this On-Site Power Advisor Article to cover some of the key aspects of good technical specifications for a fuel transfer pump set.
Multiple leaks in an above-ground fuel piping system (especially those that repeat after unions are re-tightened), are often caused by thermal expansion, and the resulting pressure buildup in the piping system.
We recommend 4 steps to prevent generator failures due to poor fuel quality. They can be found here.
We are installing an automatic fuel polishing system. How long should it run to filter the fuel adequately?
We recommend that a fuel filtration cycle be set up to circulate 25% of the fuel tank’s content every week. This schedule would allow some time for suspended contaminants and water to settle to the bottom of the tank, where they can get picked up by subsequent filtration events. Also important, a fuel maintenance system should be selected with a fuel circulation pump of sufficient flow capacity to complete a cycle within an 8-hour period. This would allow for a filtration event to be supervised from start to finish by an employee within a single work shift.
The design engineer for the overall piping system can provide this information since the pump’s outlet pressure is determined by the site piping, not the pump itself. A pump will develop whatever pressure is required to overcome the static and dynamic head of the piping system. Unless otherwise directed, our standard practice is to size the motor so that the pump can deliver a minimum of 50 PSI, without the motor being overloaded. If the design engineer requires a higher pressure, the motor size may need to increase.
The maximum vertical lift capacity of a positive-displacement pump is approximately 15′-18′. The pump should not exceed 15″Hg of vacuum.
Consider using a Disk-style silencer with flush-mounted flanges, and shorter expansion bellows instead of the typical flexible connectors. If still unable to clear the ceiling height, call us to discuss a custom design.
Yes, we can help. Contact Us with your details. We will need to know the following:
- what is the engine manufacturer, model and rating? Or…
- what is the maximum pressure drop allowed by the engine?
- what is the engine’s exhaust gas flow rate?
- what is the attenuation level for the intended silencer (in dBA) or the silencer attenuation grade (critical, hospital)?
- what size piping are you trying to use downstream of the silencer? If unknown, we will suggest the appropriate pipe size?
- what is the expected total/overall length of pipe for the exhaust piping?
- how may 90° elbows and 45° elbows do you anticipate having in the piping downstream of the silencer?
No, exhaust silencer attenuation grades (critical, residential, etc) are not regulated by any industry standard. This means that a given manufacturer’s “critical grade” silencer may perform differently from an equally-labeled product from a competing manufacturer. Whenever possible, it is best to specify sound attenuation requirements in terms than can be measured (i.e. silencer shall provide 25dBA overall noise reduction).
We are installing an exhaust system to meet RICE NESHAP. Who can I contact for third-party emissions testing services?
Try this directory.
We haven’t used it ourselves, but we hear good things about Deacon 3100.
RICE NESHAP is an acronym for the latest EPA regulations affecting stationary gas and diesel engines. Learn more here.
Flexible connectors consist of a 321 stainless steel hose terminated with couplings or flanges. They are generally between 18″-24″ long, and designed to absorb vibration between the engine exhaust manifold and the engine silencer. Steel expansion bellows feature a single-ply or multiple-ply corrugated 304 or 321 stainless steel construction, and are specifically designed to absorb axial movement. While flexible connectors allow 0.25″ axial deflection per 12″ length, an expansion bellows often provides 1.5″-3″ deflection in a 12″ length. We recommend the installation of flexible connectors at the engine outlet connection. Expansion bellows should be installed in piping downstream of the silencer, where the piping changes direction.
Ventilated thimbles are mandated by NFPA-37 where exhaust piping penetrates through combustible walls or combustible roofs. Even in seemingly “non-combustible” walls/roofs, it may be a good idea to provide an insulated thimble to protect against burning of roof sealers, coatings, stucco, etc. Wall and roof thimbles are available in carbon steel or stainless steel.
Yes, our Surge Suppression Protection (SSP) option provides a 40kA-rated SPD, pre-installed in the ATS enclosure. Other ratings can be specified to meet your requirements.
A 4 pole transfer switch is required if your generator will be considered a “separately-derived system”. This article should be helpful.

Yes, an engine with a charge-air cooled circuit can be configured with a remote cooling system. See this article for details.
Fuel flow rate expected to flow through the cooler (at full load): _____ gpm (gallons per minute)
Heat load rejected to fuel (at full load): _____ btu/min
Operating ambient temperature for the fuel cooler: ____ F
Maximum fuel cooler outlet temperature: ____ F
The spacing between adjoining remote radiators should equal 1.5-times the radiator’s fan diameter. For example, two radiators with 6′ diameter fans should be installed with 9′ spacing between them. The purpose of this spacing is to avoid hot air re-circulation, which would result in decreased cooling performance.
