Description
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.
