PGP20 Gear Pump
• Configuration and Features: Parker Hannifin's PGP020 gear pump features a compact design, measuring only 6 inches (from the mounting flange end cover) and weighing just 25 pounds. It offers various drive shaft and mounting options to meet different needs. Standard features include a rigid single-piece drive shaft and gears, as well as pressure-balanced thrust plating to ensure efficient operation. The robust high-strength cast iron body provides durability.
• Applications: The PGP020 gear pump is an ideal power配套 (Note: "配套" is translated as "power solution" here for better context in English, but if it refers to being a component, it could be "component") for the heavy truck industry and is also suitable for construction machinery and lifting equipment.
• Performance Parameters: It boasts high pressure, reliability, and a long service life.
