Gear Pump – Flange Type

The MK FLOW Gear Pump (Flange Type) is a positive displacement rotary pump designed for precise and consistent transfer of viscous liquids such as oils, fuels, syrups, resins, and chemicals. Its flange-mounted, compact design ensures easy integration into pipelines and skid-mounted systems. The pump is best known for its smooth, pulseless flow, high efficiency, and self-priming capability.

⚙️ Working Principle

The gear pump operates using a pair of meshing gears—typically external gears—that create a vacuum at the pump inlet, drawing fluid into the gear teeth and carrying it around the casing to the outlet. Because it is a positive displacement pump, it delivers a constant flow regardless of pressure, making it ideal for dosing and metering applications.
