Plunger Hydraulic Pump

GTM Plunger Hydraulic Pump is a positive-displacement pump designed to deliver high-pressure hydraulic fluid at controlled flow rates.

 

 

GTM Plunger Hydraulic Pump is available across a 24–61 cm³/rev displacement range, with rated continuous pressure up to 350 bar / 5,000 PSI and maximum pressure up to 420 bar / 6,000 PSI. Specific displacement, speed, flow, power, shaft, mounting, and control configurations vary by pump model.

 

 

High-Pressure Plunger Pump Construction
The positive-displacement plunger design delivers a defined fluid volume per shaft revolution for high-pressure hydraulic service.

 

Rigid Pump Housing
The rigid housing supports the internal pumping assembly and maintains the required structural support around the pressure-bearing components.

 

Precision Plunger Assembly
Precision-machined plungers and mating components provide controlled chamber displacement during each pumping stroke.

 

Displacement and Speed Matching
The available displacement range allows pump output to be matched to the required flow by selecting the appropriate displacement and shaft speed.

 

Drive Interface Compatibility
SAE shaft and mounting configurations provide defined mechanical interfaces for coupling the pump with compatible prime movers.

 

Hydraulic Port Integration
Inlet, outlet, drain, and control connections can be arranged to match the hydraulic circuit and available installation space.

 

Controlled Pressure and Flow Performance
The pump's displacement and shaft speed establish its theoretical flow, providing a defined basis for hydraulic circuit sizing.

 

 

Construction Machinery
Used in excavators, loaders, lifting equipment, and other construction machinery where hydraulic cylinders and motors require high-pressure fluid delivery.

 

Agricultural Machinery
Used in tractors, harvesting equipment, implements, and other agricultural machinery with hydraulically operated lifting, steering, and auxiliary functions.

 

Industrial Machinery
Used in hydraulic presses, forming equipment, production machinery, and automation systems requiring controlled hydraulic flow and pressure.

 

Mobile Equipment
Used in mobile hydraulic equipment where pump displacement, operating speed, and installation dimensions must be matched to variable working conditions.

 

Hydraulic Power Units
Integrated into HPUs to supply pressurized hydraulic fluid to cylinders, motors, valves, and other downstream hydraulic components.

 

 

GTM hydraulic plunger pumps are engineered for integration into different hydraulic systems, with pump specifications matched to equipment requirements and application conditions.

 

 

The pump configuration is defined by the hydraulic circuit and mechanical interface of the equipment.

 

Displacement & Pressure: Configured around required flow, continuous pressure, and peak pressure.

 

Shaft & Drive: Shaft size, key/spline configuration, and rotation matched to the drive system.

 

Mounting Interface: Flange, pilot, and bolt pattern adapted to the equipment interface.

 

Hydraulic Ports: Connection type, size, location, and orientation specified for the hydraulic circuit.

 

Control Configuration: Pressure or pressure-and-flow compensation available where supported by the pump series.

 

OEM Integration: Pump configuration reviewed against equipment drawings, existing pump data, and installation requirements.

 

 

GTM Pump controls key machining, assembly, and testing processes that affect pump performance.

 

Component Machining: Critical pump components are machined according to specified dimensional requirements.

 

Dimensional Control: Shaft, mounting, port, and critical mating dimensions are inspected against production drawings before assembly.

 

Assembly Inspection: Component configuration, sealing elements, shaft assembly, and connections are verified during assembly.

 

Performance Testing: Pump pressure, flow, rotation, and leakage are checked during production testing before final release.

 

Final Inspection: Product configuration, identification, and external condition are verified before shipment.
