Features
1. HANDLE
Rugged stainless steel lifting and carrying handle.
2. CABLE GLAND
The universal GAS thread of the cable gland is able to take a sheathing pipe to protect the power cable from mechanical or chemical damage due to urbulence or the aggressive nature of the liquid.
3. PRESSURISED TESTING
Every model undergoes pressurised testing to guarantee perfect assembly and operation of the gaskets, cable gland and mechanical seals.
4. DRIVE SHAFT
Drive shaft in AISI 431 stainless steel. Connection to impeller via tapered coupling.
5. MECHANICAL SEALS + V-RING
Two mechanical seals in silicon carbide (SiC-SiC) enclosed in an inspectable oil chamber. This prevents all contact between the mechanical seals and any solids or filaments in the wastewater.
6. OIL CHAMBER
Large, inspectable oil chamber to guarantee longer mechanical seal lifetime. Includes a leakage detection sensor.
7. ANTI-CLOGGING SYSTEM
The special conformation of the hydraulic part ensures the expulsion of solids and prevents fouling of the impeller.
