Pressure is one of the most commonly measured quantities in engineering, which is why exact and reliable pressure measurement is especially important. However, the characteristics of the even best sensor or transducer can be altered by a wide variety of factors. This drift cannot be prevented, and it leads to incorrect readings. Calibration allows these deviations to be measured and documented in a certificate. All pressure measuring devices that significantly affect processes or activities should be calibrated before being used. SIKA‘s mobile test and calibration devices are effective aids for performing the necessary test and calibration tasks quickly.
Pneumatic hand test pumps
Air is used as pressure media. Especially in application areas in which wetting of the test sample is not allowed or the use of aggressive or ionising substances must be avoided, air is the ideal test medium. SIKA‘s pneumatic test pump fulfils requirements that in many cases can only be covered by several pumps from other suppliers. SIKA test pumps and pressure generators are suitable for testing, adjusting and calibrating pressure sensors, pressure gauges, pressure switches, safety valves and all types of pressure devices. They are optimised in their function and use and assist in the performance of specific tests and inspections.
Hydraulic hand test pumps
Water and oil are used as pressure media. The easily operated hydraulic test pumps and pressure generators are specifically designed for the medium to high pressure range. They have a built-in reservoir for the hydraulic fluid. Pressures up to 350 bar, 700 bar or 1000 bar can be generated, depending on the model. SIKA test pumps and pressure generators are suitable for testing, adjusting and calibrating pressure sensors, pressure gauges, pressure switches, safety valves and all types of pressure devices. They are optimised in their function and use and assist in the performance of specific tests and inspections.
Hydraulic table top test pumps
The latest generation of comparison test pumps combines precision – also with high pressures – and high manufacturing quality. Depending on the model, air, distilled water and / or hydraulic fluid can be used as the test medium.
Hydraulic table top test pumps with spindle wheel
The sophisticated design of these comparison test pumps allows effortless installation of test sample including those with big nominal diameters. The integrated adapters at the pressure connections additionally allow free adjustment of the reference pressure gauge and the test sample. Filling the pressure vessel and test pressure generation are easily carried out by means of a revolving spindle. The standard pressurising medium tank installed on the test pump allows smooth filling of large volumes. Pressure fluctuations due to air and gas particles, compensation of thermodynamic effects as well as the exact setting of the desired test pressure are carried out by means of the fine adjustment (optional). Distilled water is excellently suited as calibration medium, as it can be removed without problems and without residue. For test pressures above 1000 bar (approx. 14,500 psi), hydraulic fluid is recommended since its higher viscosity allows easier test pressure generation. All parts coming in touch with the medium are made of stainless steel thus ensuring wear-free operation.
Hydraulic table top test pumps with lever
Although the lightweight high-pressure hydraulic table top pumps are compactly built, they provide a big nylon tank with a usable tank volume of 327 cm3. In combination with a delivery volume of 0.9 cm3 per piston stroke, they provide the opportunity of testing multiple test samples in parallel. They are installed directly on the delivered pressure hose or via a separate distributor block therefore saving time and making your test tasks very efficient. The integrated check valve within the pressure vessel very quickly leads to stable pressure states. The integrated safety valve protects from overloading.
