Hydraulic Power Pack

Automatic Hydraulic Power Pack, controlled by digital readout unit is designed to supply  the required oil to the load frames for loading.
Controller unit has a simple and compact configuration. The Hydraulic Power Pack is equipped with 4 wheels for easy carriage and flexible installation.
Very silent power pack can load the specimen between 1 kN/sec. to 20 kN/sec, with an accuracy of ±5%.  Safety valve (maximum pressure valve) is used to avoid machine overloading.
Maximum working pressure of the system is 400 bar.

Single Stage Pump

The single stage pump is formed by;
High pressure radial piston pump
On the single stage pump, high pressure radial piston pump is used for test execution.


The motor which drives the dual pumps in an AC motor and it is controlled by motor inverter. The variation in the oil flow is executed with the variation of the rotation speed of the motor.

Distribution Block

A distribution block is used to control the oil flow direction supplied by the single stage pump, the following parts are fitted to the distribution block; Solenoid valve, Safety valve (max. pressure valve), Load Cell and High pressure radial piston pump.

High Precision Pressure Transducer (Optional)

The Natek range of Automatic Machines can be upgraded with option High Precision Pressure Transducer special calibration Class 1 starting from 1% of the full range.
This unique performance enables the machines to be used for a considerable number of
Early age (2 or 3 days) compression strength tests
Flexural and splitting tests by using proper accessories
Mortar (Cement) compression tests by using proper accessories
Core Testing

Oil Tank

The tank includes enough oil to fill the mechanism which pushes the ram during the test.
The level and oil temperature can be seen on the indicator fitted to the tank. It has 25 L capacity. Hydraulic motor oil, number 46, must be used.

Digital Data Acquisition & Control System

The unit is designed to control the machine and processing of data from load-cells and
pressure transducers which are fitted to the machine.
All the operations of the unit is controlled from the front panel consisting of a LCD display and function keys.
The unit has easy to use menu options.
Digital graphic display unit loading rate of the time of Testing and load values can be monitored.
Digital graphic display is able to draw real-time “Load vs. Time”.


Sample, company, laboratory and test values can be entered in the programme. Load-time graphic, test reports and sample reports can be taken.
Software provides test data, results, and the load-time graphs can be seen at LCD screen.
The Automatic Flexural Testing Machine can be controlled (Start, Stop commands) by   a computer with the software free of charge. This software provides data acquisition  and management for compression, flexure and splitting tensile test throughout the test execution. The advanced functions for data base management provide an easy navigation of all saved data. The test results certificate includes all descriptive information. Therefore, test parameters can be set and details about the test carried out such as client details, test type, specimen type, user info and other information required can be entered and printed out as well as test report and graph.
Software can be performed in Turkish and English.
Test results, graphics and properties of 24 different specimens can be saved in one folder. Old test folders can be reviewed.
User can highlight all 12 different specimen curves in different colors on the graphics.
Frequently used information like name and location of the laboratory, type and dimensions of mostly used specimens are held in memory and can be written automatically by right clicking on information boxes and selecting frequently used text in menu.
User can access any data of previously completed tests and use in his/ her new report since most of the tests have same structure and properties.
