APPLICATIONS
SAER submersible motors series CL 95 are suitable to be immersed in wells having diam. 4” and larger to be coupled to hydraulic submersible centrifrugal and peripheral pumps with 4” Nema coupling.
CHARACTERISTICS
4” oil filled submersible motor, completely rewindable. Non –toxic oil (USA FDA, US Pharmacopoeia/National Formulary, USDA (Department of Agriculture), European Pharmacopoeia approved) Flange and shaft protrusion in compliance with NEMA standards 4. Degree of protection: IP 68. Insulation class: B. Shaft entirely made of stainless steel AISI 431.Outer shell made of stainless steel AISI304. Cast iron flange. A compensation membrane on the bottom of the motor ensures the balance between the internal and external pressures, along with the variation of the oil volume due to the temperature. Triple seal system on rotor shaft: bi-directional mechanical seal
+ radial seal +sand-guard with laminar seal. Single phase motors: PSC type (Permanent Split Capacitor). Capacitor have to be provided by the customer.
Rotation: Single phase motors: counter clockwise facing shaft end, three phases motors: clockwise or counter clockwise without
distinction. Cable material suitable for use with drinking water. All motors 100% tested (test report supplied upon request). SAER submersible motors are suitable for use with frequency changer.
