• Optimized pump body and impeller
The pump body and impeller are designed and refined with the use of CAD technology to ensure smooth passage of fibers and debris without clogging or entanglement. The impeller is precisely balanced, resulting in low vibration and stable operation.
• Reliable submersible motor
Specially designed submersible motor with IP 68 protection and F-class insulation. With the efficient cooling effect,the temperature rise of motor winding is low, resulting in improved motor durability. The motor dissipates heat through its casing. As long as the medium submerges at least half the height of the motor, it can operate reliably and safely. The greater the submergence, the better the motor cooling. The heavy-duty water-resistant cable is sized for full-load use at 40°C and is double-fixed at the handle to prevent damage.
• Reliable sealing and strict inspection
Shaft sealing:The use of dual shaft seals reduces leakage to one-tenth compared to double-face seal. Oil cools and lubricatesthe seals. The pump side uses hard silicon carbide pairs for low wear; the motor side uses graphite and silicon carbide for smooth sealing. Rubber parts are nitrile rubber; metal parts are stainless steel.
Cable sealing:Fully sealed cast-head cable prevents water entry. Cable ends must stay dry to ensure safety.
• Reliable bearing setup
High-quality branded deep-groove ball bearings are used, with ample load capacity for reliable operation
