potential problems of suction and unpriming.
Multi-stage close-coupled borehole pump with hydraulic
section below motor, which is cooled by the pumped
liquid. Impellers, diffusers, strainer and oil sump in
abrasion-proof thermoplastic. Outer liner, stator sleeve,
upper head with delivery connection and closing ring in
AISI 304 stainless steel. Rotor shaft extension in AISI 304.
Elastomers in NBR. Stainless steel screws.
Double mechanical seal with interposed oil chamber,
made of ceramic/carbon on motor side and silicon
carbide/silicon carbide on pump side.
Submersible with continuous duty asynchronous motor.
Rotor running on ball bearings, oversized to ensure low
noise and durability Built-in thermal and current overload
protection and a capacitor permanently on in the singlephase
version. To protect the three-phase motor use
remote overload cut-outs in compliance with statutory
regulations.
Constructed in compliance with CEI 2-3 and CEI 61-69
