Guangdong Ruirong Pump Industry Co., Ltd. will exhibit its MASTRA® submersible pump series at the 140th Canton Fair, held October 15–19, 2026, at the Pazhou Exhibition Hall in Guangzhou, China. Visitors can find RUIRONG Pump's booths in Hall 6.1 (D43-44, E05-06) and Hall 14.2 (B07-08).

Water-filled submersible motors, also known as "wet stator" motors, are submersible pump motors that use clean water or a water/glycol mixture instead of oil to cool and lubricate internal components. Because they use water-based fluid rather than oil, these motors pose virtually no risk of groundwa

An oil-filled submersible motor works by fully immersing the stator windings and rotor in dielectric oil, which simultaneously insulates the electrical components, cools the motor, and lubricates the bearings. As the oil absorbs heat, it transfers that heat through convection to the stainless steel

An oil-filled submersible motor uses dielectric oil for internal lubrication and cooling, while a water-filled (water-cooled) submersible motor circulates water through the motor cavity to achieve the same effect. Both are widely used in deep well pumping, irrigation, and industrial water supply — b

Proper submersible pump maintenance involves routine daily inspections, scheduled component servicing, seasonal preparation, and operational best practices. Together, these measures extend pump lifespan, preserve hydraulic efficiency, and significantly reduce unplanned downtime. Whether you operate
