Parker PGP511 series gear pump specifications

Parker PGP511 series gear pump：
Working pressure：
The maximum operating pressure can reach 250 bar (3625 psi), and up to 350 bar (5000 psi) in some configurations or operating conditions.
Speed range：
The maximum speed can reach 4000 rpm, some models have a maximum speed of 3500 rpm or 3100 rpm, and the minimum speed is usually 500 rpm.
Displacement selection：
Displacement ranges from 3 cm3/rev to 33 cm3/rev (0.18 in3/rev to 2 in3/rev), and a variety of specifications are available to meet different application needs.For example, common displacement includes 6 cm3/rev, 8 cm3/rev, 10 cm3/rev, 11 cm3/rev, 14 cm3/rev, 16 cm3/rev, 19 cm3/rev, 23 cm3/rev, 27 cm3/rev, and 33 cm3/Rev.
Gear design：
The PGP 511 series adopts a 12-tooth gear design, which optimizes the flow distribution structure, reduces pressure pulsation, and runs smoothly and quietly.
Material and structure：
The material of the pump body is usually aluminum alloy, which has high strength and large shaft diameter, reduces bearing load and adapts to high-pressure working conditions.
The internationally common “floating bushing” design is adopted to enhance durability and stability.
The pressure balanced bearing seat ensures maximum efficiency under all operating conditions.
Temperature range：
The maximum fluid temperature can reach 80°C (176°F) and the minimum fluid temperature is -15°C (5°F).
Viscosity range：
The maximum kinematic viscosity is 7500 SUS and the minimum kinematic viscosity is 50 SUS.
Installation and connection：
A variety of installation and connection sizes are available, and various valve parts can be integrated, such as safety valves, load-sensitive valves, priority valves, unloading valves, etc.
Support the configuration of multiple pumps with shared imports, providing flexibility in system design and application.
Port connection options include SAE, ISO, NPT, BSPP, ODT, etc.
Control method：
Support a variety of control methods, such as safety valve control, load-sensitive control, priority control, unloading control, etc.
Application area：
PGP511 series gear pumps are widely used in iron and steel, metallurgy, aluminum, petrochemical, aerospace, shipbuilding, coal, cement, electric power, automobiles, construction machinery, food, medicine, forestry, textiles, leather and paper industries.
