Gear Pump

Gear pumps are mechanical pumps frequently preferred in industrial systems for transferring a fixed volume of liquid per revolution thanks to their positive displacement operation. This makes them particularly high-performing and reliable for conveying viscous (dense) liquids.

Steady Flow for
Oils and Viscous Liquids

Gear pumps are ideal solutions for systems requiring high-pressure transfer, low flow rate applications, and continuous flow control. Through their internal gear wheels, these pumps draw in liquid, pressurize it, and deliver it steadily into the system line.

FlowLand gear pumps provide efficiency across a wide range of applications — from industrial facilities to production lines — with their capacity to transfer liquids across a wide viscosity range without issues.
