Marzocchi GHP2A-D-12-FG is a high-performance external gear pump designed for reliable hydraulic oil delivery in industrial and mobile hydraulic systems. It belongs to the Marzocchi GHP2 series, which is engineered for medium to high pressure applications requiring stable flow output, compact structure, and long service life.
According to official GHP2 series technical data, the GHP2A-D-12 configuration corresponds to a displacement of approximately 8.3 cm³/rev, with a theoretical flow of about 11.8 L/min at 1500 rpm. The pump is designed for continuous operation with a maximum pressure capability up to 280 bar (continuous), 295 bar (intermittent), and peak pressure up to 310 bar depending on system conditions. :contentReference[oaicite:0]{index=0}
The pump structure uses a high-strength aluminum body combined with precision-machined gear pairs and pressure-compensated bushings. This design reduces internal leakage, improves volumetric efficiency, and ensures stable hydraulic performance even under variable load conditions. The flange and cover are designed to withstand high pressure cycles while maintaining dimensional stability.
The GHP2 series is widely used in hydraulic power units, agricultural machinery, construction equipment, material handling systems, and industrial automation systems. It provides stable hydraulic flow for systems requiring continuous energy transmission and consistent pressure supply.
This pump is designed for clockwise rotation and supports SAE-standard mounting configurations, making it suitable for OEM installations and replacement applications. The compact design allows integration into systems where installation space is limited but reliable hydraulic performance is required.
From a system reliability perspective, external gear pumps such as the GHP2A series are valued for their simple construction, low maintenance requirements, and stable operation over long duty cycles. Proper shaft alignment, correct inlet conditions, and clean hydraulic fluid are essential to maintain performance and extend service life.
Hydraulic oil cleanliness plays a critical role in preventing wear of internal gears and bushings. Correct viscosity selection and proper filtration help maintain volumetric efficiency and reduce operating noise over time.
