According to the specifications required by the test kit for hydraulic load test on pilings, can be composed of one or more cylinders available with the following characteristics:

• Hydraulic cylinder – High tonnage cylinders, oil return;
• Capacity 100/150/200/300 TON capacity;
• Stroke 100mm/150mm.

Cylinders with special features can be produced according to customer specifications.

The pressurization units designed specifically for this type of test may be two-stage pumps with tanks from 2.3 – 4.3 to 7.8 liters with shut-off valve that eliminates stress on the lever due to stage 1, 4-way valve double-acting cylinders with high approach and ran large oil capacity.

For systems with multiple cylinders, hand pumps are recommended with two-stage valve that allows automatic switching from 1 to stage 2 and the attainment of maximum pressure with an effort at the lever content. These models are equipped with:

• Safety valve;
• Carrying handles;
• Attack by 1/2 “BSP for the gauge.

Available with 10 or 20 liter tanks and control valves 3 way, 4-way and 4-way check valve driven.

Ideal in all applications where the need for a greater economy and freedom of use compared to electrical or pneumatic control units at the same time it also requires a range and an ability more important than hand pumps above.

Other components of the system:

• One-way flow control valve to fine tune;
• N.1 NVT02B high precision digital pressure gauge 0-700bar with indication of min/max pressure peak, storage of selectable values ​​and measurement units (psi, MPa, kPa, bar, mbar), accuracy 0,20% F.S. (*);
• Hose maximum working pressure 1000bar, burst-fitting 2800bar;
• Oscillating head;
• Couplers and protective caps for joints.

IMPORTANT:

Some essential information is necessary to choose the correct pump:

• Reservoir capacity;
• Cylinder plunger speed.

After having selected the most suitable cylinder and determined the oil volume required for the stroke, it is now necessary to choose the most suitable pump based upon the required oil volume.

Finally, the quantity of oil needed to fill the flexible hoses.

The standard kits are made up as follows:
