Cartridges & Mechanical Seals

62 SINGLE SEALING PLANS SINGLE FLUIDS, Lubrication Various parameters exist that determine the durability of a mechanical seal. Temperature, pressure, speed, fluid type (sticky, laden with particles, etc.) which all have a decisive effect on wear and damage of the mechanical seal materials. To reduce these effects and improve the seal durability, API plans can be used. Below are some of the ones applicable to our products. PLAN PLAN PLAN DESCRIPTION OBJETIVE OBJETIVE OBJETIVE APLICATIONS APLICATIONS APLICATIONS In general for clean fluids that do not polymerise at moderate temperatures. Particle-laden fluids may block the flushing/washing connection. In general for clean fluids that do not polymerise at moderate temperatures. Clean liquids which may contain par- ticles. The filters may become blocked and so it is best to use cyclones in the presence of solids. To ensure the lubrication of the seal and reduce the temperature in the seal chamber. To ensure the lubrication of the seal and control the temperature. To ensure the lubrication of the seal and prevent the mechanical seal from abrasion by particles. Fluid recirculation from the pump dis- charge. This is applied as a flushing/ washing operation on the seal cham- ber. Circulation of the fluid from the pump discharge to the seal chamber, passing through a flow rate controller. Circulation of the fluids from the dis- charge to the seal chamber, passing through a filter/cyclone and through a flow rate controller. PLAN 01 PLAN 11 PLAN 12 DESCRIPTION DESCRIPTION API PLANS
