High pressure and high efficiency, with lower energy consumption
Outstanding pressure resistance performance: This series of pumps has strong high-pressure adaptability. Some models can achieve a continuous working pressure of up to 420 bar, and some special specification models can even reach a maximum pressure of 480 bar, easily meeting the operational requirements of high-pressure hydraulic systems in construction, mining and other fields.
High energy conversion efficiency: By adopting an axial plunger slipper structure and an optimized swash plate control technology, it features high mechanical and volumetric efficiency, with an energy conversion efficiency exceeding 92%. This can reduce energy loss and fuel consumption in the hydraulic system, while also lowering oil heating and reducing the load on the cooling system.
Diverse control methods and precise adjustment
It supports multiple control methods such as manual, electro-hydraulic control, pressure compensation control, and load sensing control, and can be flexibly integrated into different hydraulic control systems. Moreover, the flow rate can be adjusted steplessly through the swash plate. The response time of some models is less than 50 milliseconds, which can precisely match the speed and torque requirements of the equipment under different working conditions, such as the low-speed and heavy-load switching during agricultural machinery harvesting and the high-speed and light-load switching during transfer.
The structural design is excellent and has wide adaptability
Compact, lightweight and easy to assemble: It adopts a modular compact design, with a small volume and light weight. Compared with similar products, its weight can be reduced by 50%, and it can be adapted to equipment with limited installation space such as loaders and small excavators. It is compatible with standard installation interfaces such as SAE and ISO flange and shaft configurations, and can be seamlessly integrated into the hydraulic systems of most equipment. It also supports single pump and series pump designs. The rear end cover can be optionally equipped with auxiliary installation flanges to meet the assembly requirements of series pumps.
The integrated make-up oil pump is more practical: The integrated make-up oil pump not only ensures positive pressure in the system and avoids cavitation problems, but also provides the power needed for cooling and filtration in the system, simplifies the external pipeline layout, and enhances the overall stability of the hydraulic system.
It is highly durable and easy to maintain
Outstanding anti-manufacturing capacity: It adopts high-strength alloy steel shell, hardened steel plunger and high-strength bearings and other wear-resistant components, with strong anti-pollution and anti-impact load capabilities. It can adapt to harsh working conditions with much dust and strong vibration in mines, forestry and other industries, with an average mean time between failures exceeding 10,000 hours.
Simple maintenance and repair: It adopts a modular design, allowing internal components to be quickly disassembled for inspection and repair without the need for complex disassembly of the overall structure. This can significantly shorten the time for fault detection and maintenance, reduce equipment downtime losses, and the low-noise and low-vibration design can also reduce equipment wear and tear during operation.
There are a wide range of displacement options and strong scene adaptability
This series features multiple models ranging from S90-042, S90-055 to S90-130, with a wide range of displacement coverage. It can meet the hydraulic system requirements of different power levels, from small agricultural machinery to large construction equipment. Whether it is the small hydraulic action of the harvester or the high-power walking drive of the paver and roller, corresponding suitable models can be found.Five pieces of materials

The models you mentioned, such as TMT250 and TMT315, all belong to the TMT series of axial variable hydraulic cycloidal motors. This series of cycloidal motors is specially designed for medium and heavy-duty hydraulic systems and is often used as an upgraded alternative to the OMT series. It is compatible with various open and closed hydraulic circuits. The following is a detailed introduction from various dimensions:
Model Analysis: This series of models is marked with “TMT”. The subsequent number core represents the key parameter of the motor’s geometric displacement. The larger the number, the greater the displacement, and the corresponding output torque is usually higher. The specific corresponding relationship is as follows:
Model geometric displacement (cm³) Model geometric displacement (cm³
TMT250 251.8 TMT470 477.3
TMT315 326.3 TMT500 494.8
TMT400 410.9 TMT630 629.1
Working principle: The TMT series belongs to the rotor-stator cycloidal motor and adopts the cycloidal roller type (geroler type) structure design. The core working logic is to convert hydraulic energy into mechanical energy. The specific process is as follows: After high-pressure hydraulic oil enters the motor, it drives the internal rotor to perform revolution and rotation within the fixed trajectory of the stator. The mechanical motion of the rotor is transmitted through the output shaft, thereby driving the operation of external equipment. Meanwhile, by changing the input flow rate of the hydraulic oil, the output speed of the motor can be precisely regulated. When hydraulic oil is input in reverse, the motor can rotate in both directions, adapting to the steering requirements under different working conditions. Moreover, with its valve-controlled structure, it can ensure stable control of the inflow and outflow of hydraulic oil, achieving smooth operation at low speeds.

Specific parameters of attributes
The maximum inlet pressure of the pressure specification can reach 420 bar, and the maximum pressure difference during intermittent operation can reach 350 bar. For some models (such as TMT500), the intermittent operation pressure difference is 325 bar, and for TMT630, it is 250 bar
The continuous working speed is 200-500 revolutions per minute, and the intermittent working speed is 240-600 revolutions per minute. For example, TMT250 operates at 500 revolutions per minute continuously and 600 revolutions per minute intermittently, while TMT630 operates at 200 revolutions per minute continuously and 240 revolutions per minute intermittently
The continuous working torque of the torque output is 940-1830 N · m, and the peak torque is 1440-2740 N · m. For example, the peak torque of TMT630 is 2740 N · m, and that of TMT250 is 1440 N · m
The continuous output power is 27 to 37 kilowatts, and the intermittent output power can reach up to 63 kilowatts at most. The continuous power of most models is concentrated between 35 and 37 kilowatts
