National, MD Small Centrifugal Pumps and How They Work

Centrifugal pumps use a rotating impeller to move fluid through a system. This impeller, which is a disk with vanes or blades attached to it, is driven by a motor and the rotation exerts a centrifugal force that causes the fluid to move away from the center of the disk. Due to the difference in pressure caused by this movement, the fluid is drawn into the pump and moved through the system. In addition to transferring fluids, these pumps can be utilized to transport gases.

Centrifugal pumps' high flow rates and capacity to handle large volumes of fluid are two of their main advantages. Additionally, they have a fairly simple design that is simple to maintain. Applications for Centrifugal pumps include water treatment, irrigation, oil & gas production, and chemical processing. Centrifugal pumps come in a variety of designs, including axial, mixed, and radial flow pumps. Each type has its own distinct set of qualities and is created for particular applications.

National MD Drum Pumps

Drum pumps are utilized for a variety of industrial, commercial, and residential purposes that all entail transferring liquids from sizable drums or containers to other places where the liquid is needed. This involves moving liquids like water, oil, gasoline, and a variety of other kinds of chemicals. Drum pumps are useful for filling containers and for use in manufacturing because they can dispense fluids in precise volumes.

Drum pumps are widely used in a variety of sectors, including industrial, agriculture, and mining. Drum pumps are used in chemical processing businesses for things like food processing and pharmaceuticals. Drums are a common container in the water treatment and construction sectors, hence these businesses also employ drum pumps.

• Filter/Regulator - Compact, integrated design saves space and reduces piping, includes dual scale psi/Bar gage. Filters incoming air to five microns. Regulator adjusts air pressure from 7.3 to 120 psi (.5 to 8.3 bar).
• Pulsation Dampeners - Removes virtually all hydraulic shock while producing a near steady flow of fluid. Protect piping, valves and fittings from destructive pulsations and surges. Available in a wide range of materials of construction
• SPILLSTOP - Fully pneumatic system safely captures leaked product due to diaphragm failure and automatically shuts down failed pumps to eliminate costly product loss and prevent hazardous spills.
• Liquid Level Control - The FTI Liquid Level Control is a pneumatic/mechanical device that will automatically turn the pump on and off as the liquid level changes
• Cycle Counter - The FTI Air Cycle Counter is an electronic device that counts pump cycles by detecting the presence of the valve carrier. The cycle counter can be universally used on any new or existing FTI Air pump with the proper air valve components.
