Fluid Tech Systems is a leading manufacturer, supplier, and exporter of high-performance External Gear Pumps in India, backed by over 35 years of engineering expertise. We deliver ISO-certified pumping solutions engineered for precision, durability, and maximum operational efficiency. Our external gear pumps are widely trusted across multiple industries for their consistent output, robust construction, and long-term reliability.
As a trusted External Gear Pump Manufacturer, we design and produce high-quality pumps capable of performing efficiently in demanding industrial environments. Manufactured using premium-grade materials and advanced CNC machining technology, our external gear pumps are known for their high accuracy, excellent volumetric efficiency, and extended service life.
An External Gear Pump operates on the positive displacement principle and consists of two externally meshed gears rotating in opposite directions within a precisely machined housing. As the gears rotate and unmesh at the inlet, a vacuum is created that draws fluid into the pump chamber. The fluid is then carried around the outer periphery of the gears and discharged at the outlet side when the gears re-engage, ensuring a smooth, continuous flow with stable pressure.
Our external gear pumps are widely used in industrial applications requiring precise flow control, high-pressure handling, and reliable performance. The tight internal clearances between the gears and pump casing minimize internal leakage, improve volumetric efficiency, and maintain consistent pressure even under heavy-duty operating conditions.
Thanks to their precision engineering and positive displacement mechanism, Fluid Tech Systems’ external gear pumps deliver pulse-free, efficient fluid transfer for low to high-viscosity liquids. This makes them an ideal choice for industries that demand accuracy, durability, and uninterrupted operation.

Industries Served
An external gear pump is a type of positive displacement pump that uses two meshing gears to move fluid. One gear is driven (usually by a motor), and it turns the other gear, creating a vacuum that draws fluid into the pump and pushes it out on the discharge side.
An external gear pump works by using two meshing gears to draw fluid in and push it out. As the gears rotate, they create a space on the inlet side that pulls in liquid. This liquid is then carried around the casing in the spaces between the gear teeth and discharged on the outlet side when the gears mesh again.
External gear pumps offer high efficiency, compact size, and the ability to handle a wide range of fluid viscosities. They also provide a smooth, pulse-free flow, making them suitable for precision metering applications. Additionally, they are known for their durability and reliability in demanding industrial environments.
Regular maintenance for an external gear pump primarily involves ensuring proper lubrication, monitoring fluid quality, inspecting for leaks, and replacing worn parts.
