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.
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.

Gear Pump — Technical Advantages & Features
Constant flow rate: Delivers the same volume of liquid per revolution
High viscosity compatibility: Suitable for oils, resins, chemicals, and dense liquids
High efficiency at low speed: Delivers the required pressure and flow even at low motor speeds
Reliable performance: Provides continuous and stable operation in industrial processes
A gear pump is a positive displacement pump that transfers a fixed volume of liquid per revolution using interlocking gear wheels. It is widely used in industrial processes requiring high-pressure, continuous, and controlled liquid transfer.
Gear pumps are suitable for a wide range of liquids including oils, resins, adhesives, paints, chemicals, and other viscous fluids. They can handle viscosities from 10 cP up to 250,000 cP.
Centrifugal pumps use rotational energy to move low-viscosity liquids at high flow rates, while gear pumps use positive displacement to handle high-viscosity liquids at precise, controlled flow rates. Gear pumps maintain consistent output regardless of pressure changes.
Gear pumps are effectively used in manufacturing plants, chemical and petrochemical lines, lubrication systems, panel and hydraulic circuits, and all industrial applications requiring viscous liquid transfer.
