Tyrone Dowty Hydraulic Pumps
Orange
A Dowty pump is a type of hydraulic pump designed for high-pressure fluid transfer applications, typically found in aerospace, industrial, and automotive systems. Known for their durability and precision, Dowty pumps are widely used in systems that require reliable and efficient fluid handling.
The Tyrone-Dowty GPA3-250A hydraulic pump is a vintage gear pump that was likely manufactured before the mid-1990s. It was a product of the Dowty Group, which was acquired by the TI Group in 1992. After subsequent acquisitions, pumps in this product line are now a Parker brand.
Here's what you should know about this vintage pump:
Manufacturer: The pump was made by the Dowty Group, likely under the Tyrone brand. The Dowty Group specialized in hydraulic systems and components before being acquired.
Type: It is a gear pump, which uses the meshing of gears to pump fluid.
Application: Gear pumps like this are known for their durability and simple construction. They were used in a wide range of machinery that required hydraulic power, including agricultural, construction, and industrial equipment.
The model code: The "GPA3-250A" model code would have been used by Dowty to designate its specific size, displacement, shaft configuration, and porting. "Vintage" likely indicates the pump is from the original Dowty or early post-acquisition era.
Replacements and availability: Finding a new-old-stock (NOS) or used version of this exact pump model is difficult. However, modern equivalents from Parker or other hydraulic suppliers are available. You can also find remanufactured units or look to rebuild your existing pump with parts if available.
