Pump Selection for Fire Apparatus


In the September 2018 issue of Fire Apparatus & Emergency Equipment, I introduced the idea of pump theory driving the pumper design. I believe that pump theory should guide the decisions in the prebuild and spec process as well as having an operator who understands it as part of the committee. I hope to enable you to look at your environment for fire protection resources and ensure you are building the apparatus that best fit those needs.

THE FIRE PUMP

First, the fire pump. There are numerous factors that go into the decision for which pump to put in the apparatus. Many manufacturers have an option for a compact style pump that uses a limited amount of space. These pump choices are an addition to an extensive list of pumps available from various pump manufacturers. Hopefully, this article will give your committee insight into which one fits your needs best, but that, again, means taking a look at pump theory.

The centrifugal pump can move large quantities of water at low pressure or low quantities at high pressure. A 2,250-gallon-per-minute (gpm) pump will move lots of water if paired with a 450- or 500-horsepower engine. This would be a great choice if you need one engine to supply an aerial platform with dual monitors. The weakest link in this system would be the ability to supply the engine with water. This requires a strong hydrant or a very efficient tender operation. Another issue with using one engine to work this hard is fuel consumption. This engine will be able to complete the task, but without a fuel truck available for long-duration greater alarms, using two engines to share the work will prolong the need for fuel.

Most aerials only have a single waterway, and one engine with a 1,500-gpm pump can supply that tower easily. But, there may be a dealer demo platform that is marked down to your price range that is too good of a deal to pass up. Or quite possibly, your department already has one, but supply is an issue. Ensuring that the engine you are purchasing will handle the workload of the aerial is important.

The other instance where it is relevant to have a larger pump and engine combination is for high-rise firefighting. Most new-construction high-rise buildings have fire pumps or boosters that will aid in supplying adequate pressure to higher floors. There are still many standpipes that are dry, which can tax a single supply engine. High-rise tactics incorporate the use of smooth bore nozzles for reach and low-pressure operation, but they can come at the cost of gpm. Multiple lines on multiple floors can overwhelm a single 1,500-gpm pump, especially when having to overcome gravitational loss. A larger pump in this situation will make easier work of pumping to higher floors. One can argue that a second 1,500-gpm pump in tandem pump mode will aid the first in meeting the pressure and volume requirements, which is correct. However, the second attack engine not only is needed to assist the first but also should be considered the backup engine if the other engine in the system has a mechanical or electrical system failure. Either engine should be capable of sustaining the operation, if possible, to provide the highest degree of redundant safety for firefighters working in an extremely hazardous situation. Thus, evaluate the worst-case scenario in a structure your department protects and ensure you can meet the required flows at the pressures desired.

Five Questions for Paul Carpenter with Harrington

Chris Mc Loone

Paul Carpenter

Vice President of Sales, Harrington, Inc.

1

CM: Would you provide a brief history of Harrington, Inc.?

Paul Carpenter

PC: Harold “Hal” Harrington founded Harrington, Inc., in 1988. The company is truly a family operation. Hal passed in 2016, and Dave and Tim Harrington as well as other Harrington family continue to work at the company located in Erie, Pennsylvania. We continue to provide Harrington brand products—Hydrant Storz conversion assemblies, Storz X threaded adapters, and suction hose as introduced by Hal. Harrington has been representing AWG Fittings since Hal started the company. We are the master distributor for AWG for all North America. We maintain a large stock of AWG products for immediate delivery. Harrington brand products are proudly made in the United States AWG products are made in Germany.

2

CM: How do Harrington products help fire departments overcome their water supply challenges?

PC: Harrington products enable fire departments to connect quickly without adapters to all types of water-handling devices. Harrington introduced Storz couplings to the American fire service, and it is now the standard across the United States, Canada, and Mexico for large-diameter hose. Not needing male and female adapters assures firefighters of quick quarter-turn connections. This is imperative in the short time frame that firefighters have to make hose, building, hydrant, and appliance connections.

3

CM: What are some of the highlights of the Harrington product line?

PC: Harrington hydrant Storz conversion assemblies HPHA and HISA are another standard in the fire industry. These convert a fire hydrant outlet to use a quick-connect Storz connection.

What’s Coming in Fire Apparatus and Equipment?

Richard Marinucci

In the coming year, some recent trends will continue and others will fade away. Which ones will sustain?

It is not always easy to predict, but looking at recent history and developments in other industries can help the fire service prognosticate.

Richard Marinucci

There are likely to be some “flashes in the pans”—items, topics, and issues that will last a short time and fade away. Others will continue developing and solidify their place in the service, while others will get an introduction and may or may not pass the test of time.

One of the issues that will continue to grow and further establish roots is firefighter health/wellness/safety. Much attention has been brought to the forefront and rightfully so. This has been the result of passionate individuals, good organizations, and research from reputable institutions. This combination will ensure that this is not just a passing trend but will continue to transform the fire service. The increase in awareness along with the scientific evidence make it much harder for previously regarded “truths” to continue. It also helps one retirement at a time! There will always be naysayers (remember those who didn’t accept the proof that the earth was not flat?) who will resist hard evidence, looking to maintain the status quo. But there is too much critical mass with this subject to derail it. We can expect to see more research that either refutes previously held axioms or confirms instinctive thoughts.

Those who provide the apparatus and equipment, along with the services, that allow the fire service to deliver have certainly taken notice of this trend. The long-time supporters of the fire service have always been considerate of firefighter issues. This will continue with the newer information, and they will adjust their products and services. The “friends” of the fire service will remain friends.

We can also expect to see other companies enter the market. This can be those that have been engaged in health and wellness issues in other occupations or new companies. Regardless, there will be more options, and with this comes the need for the fire service to do its research and due diligence when evaluating products and services.

One of the issues that arises with most changes is the influx of new ideas and products related to the new program. The question becomes one of whether there is benefit to the long-term development. As an example, I was reading recently about the many companies trying to provide products and services to address the tragic mass shootings of late, particularly those in schools. They all claim to have the “silver bullet” that will guarantee protection. Of course, many in law enforcement and the school systems are taking the time to evaluate each one to make sure they can deliver on their promises.

Within the fire service, we can expect to see similar introductions in our “hot topics.” Many will be in response to recent revelations about the inordinate impact the job has on cancer rates. It is safe to say that some will be beneficial while others will have no or limited impact. It will be up to those in the fire service to do the proper vetting so that they get what they were <
