ETD type single stage pipeline circulation pump, equipped with standard motor and mechanical seal, has a structure that is less susceptible to impurities in the pumped liquid compared to similar types of products.

The product is designed in a detachable form that can be pulled out from the top, allowing for pump maintenance without affecting the piping system. The ETD32-ETD150 caliber products have an extended shaft structure, while the ETD200-ETD300 caliber products feature a detachable structure with a containerized mechanical seal, eliminating the need to disassemble the motor during seal replacement.
