CONSTRUCTION FEATURES OF THE PUMP
The use of advanced stainless steel processing technologies for the main hydraulic components helps to achieve very high performance levels.
The center distance of the in-line ports are designed to maximize interchangeability.
Pump body and upper flange are in cataphoretic cast iron; impellers, diffusers and pump liner are made in AISI 304 stainless steel (AISI 316 stainless steel available on request - X version).
Round flanges as standard (oval, loose, Victaulic, clamp available on request).
The mechanical seal is made of standard E1 = Graphite/Silicon Carbide/AISI 316/EPDM = BQGE.
FKM/Viton available on request. Starting from 5,5 kW models, the mechanical seal can be removed without removing the motor.
Rigid coupling.
