The "heart" of any hydraulic system, the hydraulic pump converts mechanical energy (from an electric motor or internal combustion engine) into hydraulic energy (flow and pressure). This device supplies hydraulic fluid to actuators such as cylinders or hydraulic motors to operate machinery. QME offers a full range of hydraulic pumps to meet all industrial needs with high efficiency and superior durability.
Radial piston pumps are the optimal solution for hydraulic systems requiring extremely high working pressures (up to 700 bar or more) and durability in harsh industrial environments. At QME (Quang Minh Equipment Corporation), we supply genuine radial piston pumps from leading global brands (Bosch Rexroth, Hawe, Moog, etc.), meeting the stringent standards of steel, cement, plastics, and heavy industry plants.
Axial piston pumps are the heart of modern hydraulic systems, distinguished by their ability to operate at high pressure and a wide flow rate range. They are the preferred solution for applications requiring flexibility and optimal energy efficiency. At QME (Quang Minh Equipment Corporation), we offer a full range of swash plate and bent axis axial piston pumps from leading global brands such as Bosch, Rexroth, Parker, Eaton, etc., ensuring absolute reliability for your production line.
Fixed displacement piston pumps are high-performance hydraulic pumps that deliver a constant flow of fluid with each rotation. With their ability to generate very high pressure and maintain excellent volumetric efficiency, they are the heart of heavy-duty industrial hydraulic systems. QME supplies genuine fixed-displacement piston pumps from leading global hydraulic brands, meeting stringent technical standards for operation, maintenance, and replacement in factories.
The variable displacement swashplate axial piston pump is a premium hydraulic pump that allows for the flexible adjustment of flow and pressure during operation by altering the swashplate angle. This is a core solution for hydraulic power units requiring precision, energy efficiency, and continuous operational performance.
Closed-loop variable displacement piston pumps are the heart of hydrostatic transmission systems. The fundamental advantage of a closed-circuit design is that hydraulic fluid from the motor is routed directly back to the pump's inlet, bypassing the tank. This enables smooth, dynamic motion reversal without relying on complex directional control valves.
External gear pumps are among the most popular positive displacement hydraulic pumps in the industry today. By utilizing the meshing action of two gears (the drive and idler gears) within the casing, these devices deliver a constant flow rate with outstanding reliability.
The internal gear pump is a premium positive displacement hydraulic pump that operates on the principle of an inner driving gear rotating and driving an outer ring gear in the same direction. This unique design, combined with a crescent-shaped seal that separates the suction and discharge chambers, delivers excellent, smooth fluid transmission efficiency.
Indirect control variable displacement vane pumps (variable displacement vane pumps) are hydraulic pumps designed to automatically adjust their output flow based on the system's pressure level. Instead of directly altering the mechanical stroke, these pumps utilize an auxiliary hydraulic piston (pressure compensator) to adjust the eccentricity of the cam ring, helping to maintain stable pressure and protect the entire system.
Direct control variable displacement vane pumps are hydraulic pumps that allow operators to change the output flow by directly applying mechanical action (via an adjusting screw or handwheel mechanism). This action alters the eccentricity of the cam ring (stator) relative to the rotor. Unlike indirect control models (which use hydraulic pressure), this mechanism provides proactive, simple flow intervention with immediate mechanical feedback.
Fixed displacement vane pumps are hydraulic pumps that provide a constant output flow per revolution of the pump shaft. Featuring a design that includes a rotor, vanes, and a fixed cam ring, these pumps are favored for their ability to maintain steady flow, high reliability, and extremely quiet operation within hydraulic drive systems.
Double fixed displacement vane pumps are advanced hydraulic solutions that integrate two separate pump cartridges within a single housing, driven by a single common shaft. This design allows the system to provide two independent or combined flow outputs to serve different work cycles, offering extreme flexibility for industrial machinery.
