R Series
Cast iron / brass radial submersible pumps R
Well pumps and electric pumps
TECHNICAL FEATURES:
These new radial submersible electric pumps for 6 "8" wells consist of a modular series of elements encased within a steel shell and allow the disposal of relatively low flow rates with high operating heads. The diffusers are made of polycarbonate for the 6 "pumps and of cast iron for the 8" ones. The radial flow impellers, dynamically balanced and locked on the splined shaft, are made of brass. The AISI431 stainless steel pump shaft is guided by rubber bearings at each intermediate body, and by a bronze bearing housed in the suction body. The latter, made of steel for the 6 "pumps and cast iron for the 8" ones, allows the connection to the motor and protects the shaft coupling. The delivery body in steel for 6 "and in cast iron for 8", is threaded 3 "Gas and houses the flap of the closing valve.
