T-SYSTEM SERIES GEAR PUMPS AND MOTORS
Menu
The T-System gear pump is one of the most widely used components in modern hydraulic systems.
It is known for its high versatility, remarkable strength, and long service life.
The careful selection and high quality of materials, along with the attention to the production process, allow Marzocchi gear pumps to achieve high and consistent quality standards.
For this reason, these products can operate under demanding working conditions and enable the transmission of high hydraulic power.
All this, combined with excellent hydromechanical and volumetric efficiency, low noise emissions, compact dimensions, and a low weight-to-power ratio, makes them ideal for a wide range of applications.
Marzocchi T-System Gear Pump series represents a high-performance extension of the classic size 2 Marzocchi pumps, enhanced with structural elements designed to withstand high radial and axial loads.
At the core of the system is a cast iron front flange combined with a double row ball bearing (option “J”), which provides rigid and constant support even under extreme dynamic conditions.
The ALP2-T, ALM2-T, GHP2-T, and GHM2-T models can be configured with various flanges (European, A, BK1), shafts (conical, splined), and ports (E, FA, D), with internal or external threaded drain ports according to SAE J1926/1 – ISO 11926-1, using O-rings for sealing.
They are compatible with pumping groups already known in industrial and mobile applications, maintaining the same internal geometries as standard versions, but with external components and mechanical supports designed for prolonged service life even under continuous load.
These pumps are ideal for:
High-pressure presses and cylinders
Drives under cyclic stress
Systems with critical radial and axial loads
Installations with high torque and reliability demands
