HP330A546MEAB1743 Hydraulic Gear Pump Heavy Duty Cast Iron Gear Pump PGP330 Replacement Pump

Hydraulic Gear Pump Introduction

Model HP330A546MEAB1743 is a heavy-duty ductile iron external gear pump from the HP330 series, equivalent to the PGP330 standard hydraulic gear pump. It is a core power supply component for the hydraulic systems of mobile machinery. The pump features a three-section cast iron housing structure, suitable for 241 bar high-pressure heavy-duty conditions. Original dimensions, flanges, ports, and shaft types are fully compatible, allowing direct replacement of the original pump body. It is widely used in hydraulic lifting and steering assistance systems for dump trailers, loaders, sanitation vehicles, agricultural machinery, and road construction equipment.

Our gear pumps are 100% compatible with major brands such as Parker. Made of ductile iron, they offer superior hardness and are less prone to damage. The heat-treated shaft doubles their efficiency. Quality rivals original equipment manufacturer (OEM) pumps, but at only one-third the price.

Hebei Runhe Hydraulic Machinery Co., Ltd. – With over 12 years of experience in hydraulic technology. In addition to hydraulic gear pumps, our products also include hydraulic cylinders, hydraulic gear motors, and accessories. Meticulous manufacturing helps you expand your market.

Package

Normally, it is packaged in cardboard boxes and then shipped on pallets or wooden crates. 

Hydraulic Gear Pump Advantages

• Simple structure and high reliability: Utilizing a classic external gear design, it has fewer moving parts, fewer potential failure points, and strong durability, making it less prone to damage under high-load, continuous operating environments (such as mining and large-scale earthmoving).
• Small size, light weight, and easy installation: The pump body is compact (suitable for the narrow engine compartments of excavators), easy to disassemble and replace, and has low maintenance costs.
• Stable flow and low pulsation: Uniform gear meshing provides a stable, low-pressure oil source, ensuring a fast and precise response from the pilot control circuit, with no noticeable pulsations, a smooth operating feel, and support for coordinated compound actions.
• Strong self-priming capability and resistance to dry running: Excellent self-priming performance prevents cavitation during startup, and short periods of dry running will not cause immediate damage, making it suitable for complex working conditions.
• Good pressure and temperature resistance: It can withstand the common pressure and temperature ranges of pilot systems. Materials are mostly cast iron/aluminum alloy + precision gears, providing strong wear and contamination resistance.
