1. Pump body and seal holding disk designed with suitable thickness to guarantee greater resistance and life to the exercise pressures. A wide range of materials (cast iron EN-GJL-250, spheroidal cast iron EN-GJS-500, marinebronze G-CuSn 10, stainless steel AISI 316). Flanges in PN 10 and PN 16.
2. On demand, versions with wear rings, easy to replace, to protect the pump body and the impeller (optionals).
3. Hydraulic designed with CFD systems and optimized in order to obtain the best hydraulic efficiency levels, combined with a wide range of Capacity-Discharge Head curves. Wide range of materials (cast iron, carbon steel, marine bronze G-CuSn 10, stainless steel AISI 316).
4. Different configurations of mechanical seal or gland packing according to the user's requirements, based on the fluid characteristics and the use conditions.
5. Oversized ball bearings and protected from outer agents to offer a reduced working noise and a long service life without necessity of maintenance. Available versions with oil soaked bearings and with a constant-level oil feeder on demand.
6. Standard: stainless steel AISI 431 shaft designed to resist to the bending-torsion load generated and protected by anti-wear systems. On demand, shafts made with different materials (Duplex, AISI 630).
- Dimensions according to EN733 (DIN24255) standard
- Hydraulic part simple to disassemble, extractable without needing to remove the pump body from the pipes (Back pull out system).
- Suction profile conceived to increase the suction capacity and to reduce the NPSH and the possibility of cavitation.
