TECHNICAL FACTS | PRESSURE TANK

Reliability Training

KALLER - THE SAFER CHOICEPressure TankPressure Tanks are used together with the EO24-Hose system (or its equivalent) in applications where a low pressure/force build-up in the Hose System is advantageous (e.g. for deep draw tooling applications).By incorporating a Pressure Tank into your Hose System, the overall gas volume in the Hose System increases, which causes the pressure/force build-up to be kept to a minimum.

Apart from the technical advantage of having a low pressure/force build-up in the Hose System, the service lifetime of the gas springs connected in the Hose System is also improved.

Please note!Before incorporating pressure tanks into your Hose System, consider whether it is possible to use a longer nominal stroke gas spring of the same model.

This method will have the effect of increasing the internal gas volume in your Hose System, thus reducing the pressure/force build-up.

Approximate calculation of isothermal pressure force build-up:

Pressure force build up ≈ VPTPT + (n*VGSGS )

VPTPT + (n*(VGSGS – S*A))

VPT = Volume of Pressure Tank (l) (see table above)VGS = Gas volume of gas spring (l) (see respective spring model)S = Stroke length of gas spring (dm) (see respective spring model)A = Piston rod area of gas spring (dm²) (see adjacent table)n = Number of gas springs

Example:Ten TU 5000 gas springs with stroke length 50 mm are connected to a Hose-System with one 8 litre Pressure Tank (2014342-800).

Pressure force build up ≈ 8 + (10.0.51 )

8 + (10.(0.51 - 0.5.0.332))≈ 1.145

Max. charging pressure 150 bar (at 20°C)

The bracket consists of a rubber-covered ring of galvanised sheet steel and is used to secure the Pressure Tank, preferably with one bracket at each end. If the tank is mounted vertically it should also rest on a solid support, see figures below.

PRESSURE TANK | TECHNICAL FACTS

Installation Example, Pressure Tank with EO24-Hose System

Please note the following before installing a Pressure Tank into your Hose System:

• Use only hoses designed to allow for gas flow, such as the EO24-Hose system orits equivalent

• Connect a Control Block to one of the Pressure Tank’s connection ports

• For optimal function each gas spring should be directly connected to one ofthe Pressure Tank’s connection ports

The Safer Choice

Dual Seal

Overstroke Protection System

SAFETY. When a gas spring is overstroked, this helps reduce the risk of tool damage or injury.

PED approved for 2 million strokes

RELIABILITY. Our 2 million stroke PED approval ensures safer component cycle life.

Overload Protection System

SAFETY. Jammed cam or tool part being forced by gas springs? This will help reducing such risks.

Overpressure Protection System

SAFETY. Vents the spring if the internal gas pressure exceeds the maximum allowable limit to prevent accidents.

Flex GuideTM System

RELIABILITY. Prolongs service life, life, allows more strokes per minute, and offers greater tolerance to lateral tool movements.

Dual SealTM Link Systems

RELIABILITY. Fewer production interruptions due to leakage caused by vibration. Simplified installation thanks to the non-rotation feature.

KALLER Training Program

TRAINING. Without doubt the KALLER Training Program is the best and most creative way to fully understand and appreciate the importance of the safety and reliability features.

Introduced in 1983, the KALLER gas spring technology quickly led to world-wide demand. The Safer Choice - Training, Safety and Reliability - has always been a KALLER top priority for providing the safer working environment. We recommend looking through all available KALLER features when selecting gas springs and gas or hose linked systems.
