The PGF3 series hydraulic gear pump utilizes the principle of positive displacement to generate hydraulic power.
It consists of two meshing gears—an external gear and an internal gear—enclosed in a housing. The rotation of the gears creates chambers that trap fluid and transport it from the pump's inlet to the outlet. This design ensures a steady flow of hydraulic fluid and enables the pump to handle high pressures.
The PGF3-3 model is a compact hydraulic gear pump with a displacement of 3 cm³/rev (cubic centimeters per revolution). It is suitable for applications requiring moderate flow rates and pressures. The pump is designed to operate at a maximum continuous pressure of 250 bar (3625 psi) and a peak pressure of 280 bar (4060 psi). It offers a maximum speed of 3500 rpm, making it suitable for a wide range of industrial and mobile hydraulic systems.
On the other hand, the PGF3-310 model is specifically designed for heavy-duty applications that demand higher flow rates and pressures. With a displacement of 310 cm³/rev, this pump delivers substantial hydraulic power. It can operate at a maximum continuous pressure of 280 bar (4060 psi) and a peak pressure of 300 bar (4350 psi). The PGF3-310 model offers a maximum speed of 2000 rpm, making it suitable for applications where high flow rates are required.
Both the PGF3-3 and PGF3-310 models feature a robust construction and are made from high-quality materials.
The pump body is typically constructed from cast iron, providing excellent durability and resistance to wear. The gears are precision-machined to ensure smooth operation and efficient fluid transfer. The pumps are designed for long service life and can withstand harsh operating conditions.
The PGF3 series pumps are equipped with a shaft seal that prevents hydraulic fluid leakage. This seal is typically made of high-quality materials such as Nitrile Butadiene Rubber (NBR) or Fluorocarbon (Viton). It ensures a reliable and leak-free operation of the pump.
These hydraulic gear pumps are designed for easy installation and maintenance. They have standard SAE mounting flanges and shafts, which allow for simple integration into hydraulic systems. Regular maintenance involves checking and replacing the hydraulic fluid, inspecting the seals for wear, and monitoring the pump's performance to ensure optimal operation.
