Introduction to Dowty Hydraulic Pumps
If you’ve ever worked with heavy machinery, you know the heart of the system lies in its hydraulics. Dowty hydraulic pumps are a name trusted worldwide for delivering reliable, consistent performance. Whether in an industrial plant or on a farm, these pumps are built to keep things moving — literally.
History and Legacy of Dowty Hydraulic Pumps
Origins of Dowty Group
Dowty Group, founded by Sir George Dowty in 1935, began with aircraft components. Over the years, they expanded into hydraulics, earning a global reputation for quality engineering.
Evolution of Hydraulic Technology
From basic gear-driven designs to advanced piston systems, Dowty has been at the forefront of hydraulic innovation, adapting to modern needs while keeping durability as a priority.
What are Dowty Hydraulic Pumps?
Basic Definition
A Dowty hydraulic pump is a device that converts mechanical energy into hydraulic energy, moving fluids under pressure for various applications.
How They Work
They operate by creating a vacuum at the pump inlet, allowing fluid to enter, then pushing it into the system using mechanical force — simple yet highly effective.
