CHETRA mechanical seal 151CAF in operation
CHETRA mechanical seal 151CAF in operation with Plan 23/61 according to API 682 Shown here is a modified BB pump in South America in a boiler feed application. ✔️ Temperature: 150 °C ✔️ Max. pressure at the mechanical seal: 55 bar ✔️ Speed: 3560 rpm ✔️ Viscosity: 0.26 cP Why a boiler feed application? Preventing scale formation Minerals such as calcium and magnesium in the feed water can deposit as a hard layer on the boiler walls. This reduces heat transfer, increases energy consumption and can lead to overheating and damage to the tubes. Avoiding corrosion: Oxygen and other corrosive substances in the water can attack and damage the boiler and the connected equipment. Treatment removes these harmful elements to prevent corrosion. Ensuring steam quality: High steam quality is important for protecting downstream equipment. Impure steam can cause damage. Improving efficiency: Removing impurities allows heat transfer to be optimised, which leads to higher efficiency and lower energy costs. Increasing reliability and safety: Clean water prevents equipment failures and ensures safe and stable operation of the boiler, which requires a constant water level. Reducing maintenance costs: Effective water treatment minimises the need for cleaning and repair, which lowers operating costs. Environmental protection: More efficient boilers reduce energy consumption, which has a positive effect on the environment and can support compliance with environmental regulations.
Our Test Rig for Mechanical Seals
Testing before things get serious. Quality doesn't start with the finished product, it starts on the test rig. At CHETRA, we rely on thorough testing under real conditions before a mechanical seal leaves our premises. Our test rig at a glance: ✔️ Speed-controlled DC motor ✔️ Continuously variable gearbox ✔️ Torque measurement & surface thermocouples to monitor the seal face temperature Our supply system completes the setup: ✔️ Test runs with all common API plans according to API 682 4th Ed. ✔️ Operation with an external circulation pump possible ✔️ Coriolis flow measurement in the circulation lines ✔️ Continuous recording of pressure, temperature & flow
