Fire PumpsSitting silently in basements and the bottom floors of skyscrapers, fire pumps are used to send water with high volume and pressure. When system demand exceeds what the water source can supply they help bridge that gap.The fire pump is the heart of any water-based fire suppression system. Explore our assortment of UL and FM approved fire pumps for sale to find the right one to fit your needs.Centrifugal PumpsCentrifugal pumps use a motor to rotate an impeller attached with vanes which force water toward the center of the casing, leading it to be ejected from the pump through an outlet. They’re known for their ability to withstand high pressure and are best suited for fluids that don’t contain solid particles unless the pumps are adequately sized to accommodate them.They’re available in a variety of materials including cast iron, bronze, stainless steel and aluminum to meet the needs of specific applications. Some can also handle potable water if they are NSF-certified.The smooth flow generated by centrifugal pumps makes them an ideal choice for applications such as chemical transfer, wastewater, slurries, plating solutions and cooling systems. They’re easy to maintain and offer a cost-effective solution for industrial pumping requirements. They’re also efficient and can produce moderate to high head with a range of flow rates depending on the conditions.Vertical Turbine PumpsVertical turbine pumps (VTPs) are centrifugal pumps containing stacked pump bowls that move liquids vertically instead of horizontally. They’re commonly used for a wide range of applications, including fire protection systems.A motor drives a set of shaft bearings, which in turn support the column pipes and impellers in the pump. The shaft pipe columns are flanged or threaded to accommodate different types of piping systems. The bowls can have bell-mouth inlets for well systems, or a variety of other options such as diffuser-shaped inlets for open basin systems.In some instances, VTPs are installed inside individual suction barrels. This is often employed when pumping hydrocarbons, and it leverages gravity to increase the amount of available suction pressure (NPSHa) for improved operational efficiency.VTPs can also be designed to be self-priming, which means that they don’t require a person to remove air from the system or fill it with liquid to start operating. This saves time and money when it comes to servicing and maintaining this type of equipment.End Suction PumpsEnd suction pumps are a centrifugal pump that has one impeller with the casing on which it sits mounted outside. This type of pump is used in a variety of industrial applications, including chemical, petroleum and wastewater transfer processes. End suction pumps offer a lower up-front cost and are more economical in the long run. They also require minimal maintenance.The back pull out design and spacer coupling of end suction pumps facilitates maintenance without disturbing the alignment with the motor. They are a great choice for environments that cannot accommodate split case pumps.Unlike close-coupled designs, frame-mounted end-suction pumps are designed to be mounted next to the driver (electronic motor on a typical baseplate coupled together with a flexible coupling). This allows for the pump to be dismantled or removed and easily serviced. They are also more durable than split-case pumps as they have thicker casings to handle high working pressure, vibration and thrust forces from water turbulence in the casing.In-Line PumpsInline pumps are a variety of centrifugal pump that is used for many different applications. They can be either single-stage or multi-stage depending on the application needs. Multi-stage pumps are often better for booster applications and the pressurization of fluids while single-stage are ideal for direct and low-pressure applications.Another benefit of inline fire pumps is that they can be easily repaired and maintained. They can be removed from the piping without disturbing the piping system which makes them easier to repair and service. In addition, they can be built to handle many types of conditions including mild-temperature and low-pressure situations.These are a great choice for commercial building hydronic heating and domestic hot water circulation systems as well as industrial cooling solutions. They can also handle sanitary applications. These pumps are easy to maintain and can operate 24/7. They have a robust double bearing design that can withstand heavy duty usage and harsh operating conditions.
