3.5′′ Folding Impeller Series

1、Performance Characteristics

• Performance characteristics

1.1 High-grade Stainless steel for casing of motor and pump, shaft coupling, fastener, etc, elegant appearance, strong decay resistance, outstanding durability；

1.2 High-efficient and energy-saving motor is suitable for drinking water, filled with food-grade white oil, non-toxit and pollution-free；

1.3 Motor has a built-in oil bag, largely regulating motor pressure. When motor internal pressure change, the oil bag will balance the pressure of the inside and outside, expanding the motor diving depth range, and lubricating the mechanical sealing static ring, to prolong its service life；

1.4 Adopting the flow field simulation design of CFD and the finite element analysis method, using the computer-aided design software such as CAD, Inventor, etc, to visualize the product structure；

1.5 The installation of the motor rotor conforms to “NEMA” standard；

1.6 Folding impeller adopts whole-stage floating structure, high-strength and abrasion-resistant modified composite PC for impeller and diffuser, large flow, high lift.
