Materials Pump housing: EN-GJL-250 Impeller: EN-GJL or EN-GJS Static gaskets: NBR Fluid-side seal: Mechanical seal made of SiC/SiC Motor-side seal (depending on type):-Rotary shaft seal made of NBR- Mechanical seal made of SiC/SiC or carbon/ceramic Motor housing: EN-GJL-250 Shaft: Stainless steel 1.4021 Construction Submersible sewage pump as submersible monobloc unit for stationary and portable wet 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. All motors have a sealing chamber that protects the motor from fluid ingress. It can be accessed from the outside and can optionally be monitored with a rod electrode. All filling fluids used are potentially biodegradable and environmentally safe. The cable inlet is longitudinally watertight, the cable length is 10 m and the cable has free ends.

Seal Fluid-side and motor-side sealing is possible in the following versions depending on the motor type: Version H: Mechanical seal for the fluid side, rotary shaft seal for the motor side Version G: Two independently-acting mechanical seals Ex-approval The motors have ex-approvals according to the ATEX directive. Scope of delivery Submersible sewage pump ready for connection with 10 m connection cable without plug Installation and operating instructions Accessories Suspension unit or pump support foot Various pressure outlets and Storz couplings Chains Fixation sets with anchor bolts Switchgear, relays and plugs

Commissioning Operation with non-immersed motor Surface-cooled motors (T motors) can be non-immersed only if an operating mode is specified for non-immersed operation! Observe the specifications on the rating plate. Dry-running protection The hydraulics housing must always be immersed to prevent air from being drawn in. In the case of fluctuating fluid levels, the system should shut down automatically as soon as the minimum water submersion is reached. Horizontal installation Horizontal installation is not possible!
