Vortex pump EMU FA series

wastewaterwith asynchronous motorsubmersible

Operationally reliable thanks to vortex hydraulics and single-channel hydraulic systems with large, free ball passage Process reliability thanks to optional monitoring for the sealing chamber Design Submersible sewage pump without cooling system for continuous duty for stationary and portable wet well installation. Application Pumping of Sewage containing faeces Pre-cleaned sewage without faeces and long-fibre components Wastewater Equipment/function Heavy-duty version made of grey cast iron Dry motors with ex-protection in accordance with ATEX Winding temperature monitoring Construction Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation. Hydraulics The outlet on the pressure side is designed as horizontal flange connection. The maximum possible dry matter content is 8%, depending on the hydraulics and impeller type. The following impeller shapes are currently used: Vortex impeller (W) Single-channel impeller (E) Each single-channel hydraulic system is equipped with an impeller wear ring and casing wear ring made of hardened material. These ensure long-term uniform efficiency of the unit and minimize maintenance costs. Motor Surface-cooled motors (T motor) do not have a cooling system of their own and emit their heat directly to the surrounding fluid via the housing parts. The motors can therefore be used in immersed state for continuous duty. Depending on their size, they can also be used in non-immersed state for short-time duty.
