Product details
The product description specifies single- or double-channel impeller arrangements and mechanical seals separated by an oil chamber. A leakage sensor and winding thermal elements support motor protection. Actual permissible solids and fibre loading depend on the chosen hydraulic size and should be verified for the waste stream.
Fixed installations can use a twin-guide-rail automatic coupling system; mobile installations use a free-standing arrangement. Float control and a protective control cabinet are options to define in the package. The source lists a medium temperature ceiling of 60°C, but the final motor duty and cooling conditions still need checking against wet-well operating levels.
SELECTION NOTES
Specify the operating duty
Provide wastewater composition, largest solids, fibre content, flow, head, pit dimensions and start/stop levels. Confirm impeller passage, coupling arrangement, control cabinet and motor protection.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
