4" OIL COOLING 

• Efficient and precise mechanical seals.

• The motor housing and bottom cover adopt stainless steel 304.

• Cold-rolled high-efficient and precise silicon steel sheet is adopted for laminations, with low loss and good magnetic conductivity.

• High-precision silent bearing enables the pump long service life and more stable operation.

• The stator adopts H class (200 degrees) high temperature resistant pure copper wire, low-temperature rise, safe and reliable, suitable for long-term continuous work, long service life, environmental protection, and energy saving.

• Plug-type cables can be used to make cable replacement more convenient.
