The operation of wells with fluid temperatures exceeding 302-392 °F (150-200 °С) using standard pumping equipment not adapted to high temperatures is impossible: each unit is incredibly overheated, which leads to the destruction of pump components and melting of motor and seal components.
In our solution, we use high-temperature elastomers and mechanical seals in the hydraulic protection unit. Lex high-efficiency PM motors have no electrical or magnetic losses and are less heated. In addition, they use a high-temperature-resistant synthetic oil and a special wire compound.
All these improvements have provided reliable, stable operation of submersible equipment with a comprehensive delivery range, with internal engine temperatures reaching 482 °F (250 °С) in wells with extreme fluid temperatures up to 392 °F (200 °С).
