 It takes more than just water to put out a raging fire.You’ve also got to have a way to deliver the water to the fire. This is why a quality pump is such a critical component of your fire apparatus. The fire truck pump you choose will depend on a host of factors, including the types of calls your department responds to, the water sources available and of course, cost. Let’s take a look at some of the different types of fire truck pumps and features you’ll want to consider when making a selection for your next fire apparatus. CENTRIFUGAL FIRE PUMP In use for over a century, centrifugal pumps are the most common type of fire truck pump. Water enters the pump through an inlet, then goes into the center of an impeller spinning on a shaft. The water spins outwardly through the impeller vanes into a volute casing, which increases pressure. A centrifugal pump can draft from unpressurized water sources with help of a primer. Centrifugal pumps come in different “stages,” which refer to the num

  Did you secure a new job that requires you to drive around in a dump truck? Congratulations! That’s awesome news. Just between us, we’d understand if you don’t have a whole lot of experience when it comes to operating this kind of vehicle. Sure, other commercial trucks may be similar, and they’ll certainly help you understand how the dump truck moves and operates. However, there’s not another type of vehicle on the road like a dump truck, meaning you’ll certainly need to catch up on some tips before you take the road. Otherwise, you could be risking the truck’s well-being and your own well-being. Fortunately, we’ve provided all of the advice that you could possibly need below. Whether you’re looking for guidance on operating the vehicle, preparing the truck, or dumping materials, we’ve got you covered. You won’t truly grasp what it takes until you’re actually sitting in the driver’s seat. However, our guide should at least give you a head start. Who knows; when you’ve finished readin

  You probably understand the importance of your car's engine. Without a working engine, you won't get very far. But most of us don't know much about how vehicle engines work. When identifying your car's engine type, it usually comes down to the cylinders. So, what exactly is a cylinder? We'll go over this, as well as some other engine parts you should know about. You probably already know that cylinders are an important part of your car engine . Whenever you look at a new car, the number of cylinders is usually located front and center. Most of us associate the number of cylinders with power, and there's nothing wrong with that. Car cylinders are a lot like the pot you use to cook your food. It's not the cylinder itself that is powerful, but what it holds. Car cylinders contain fuel. The more cylinders you have, the more fuel you can use at one time. It's the same with cooking pots and pans. You can cook 2 liters of soup in a 1-liter pot. The cylinders

  The installation of a fire pump system in a commercial or industrial property is a common occurrence. Using a fire pump system may allow a property to be developed where sufficient water pressure is not available 1. Principle of operation Diesel engines require a fuel injection pump that delivers clean fuel to the engine, usually under gravity pressure. The fuel supply tank should be positioned so that the supply line connection to the engine is no lower than the height of the engine fuel delivery pump. The engine manufacturer's fuel pump hydrostatic head pressure limit must not be exceeded when the fuel in the tank is at its maximum.   2. Fuel storage There are two types of fuel tanks available in today's market: single-walled tanks and double-walled tanks. Although single wall tanks are initially cheaper, and overflow containment system must be provided for the full tank capacity. By design, double-walled tanks include an overflow containment device. Their holding space mus
