Based on the worldwide proven hydraulic design of the SCE model, the SCE-M is a sealless centrifugal pump, 100% leakage free, avoiding high maintenance costs and usage of mechanical seals. It is the best option for heavy chemical handling applications, in completion to API 610 pumps for the majority of applications in the pretrochemical industry and refineries.

With over 130 hydraulic combinations available for the SCE-M pump, almost all customer requirements are met. To enhance performance and optimize efficiencies, the SCE-M counts with three different impellers for each pump size. It is built with the latest engineering techniques and tools such as 3D modelling and Finite Element Analyis to assure the best product quality.
