KTZ-LH / Submersible construction and site drainage
The KTZ-LH catalogue combines two submersible drainage ranges with cast-iron construction and high-chrome-alloy impellers. KTZ has a semi-open impeller and ductile-iron wear plate; LH has a separately specified construction for deep-well pre-dewatering and high-head drainage. Both ranges list civil engineering, mining and treatment-plant applications.
Range bounds are a catalogue overview. Check flow and head together on the selected model curve; maximum values are not a guaranteed combined duty point.
Series catalogue ↗Series overview
KTZ uses rigid cast-iron motor and pump bodies, a semi-open high-chrome-alloy impeller and a ductile-iron wear plate. Its discharge channel is cast into the motor housing for cooling, with a top outlet. LH has its own construction schedule: hard cast-iron motor and pump bodies, a high-chrome-alloy impeller and a ductile-iron diffuser; its hydraulic section sits below the motor and pumped water provides cooling.
The LH overview includes deep-well pre-dewatering and high-head dewatering. Both ranges specify water up to 40 °C, but the maximum water depth is 25 m for KTZ and 30 m for LH. Select the exact family and model by flow, total head, actual liquid, electrical arrangement and installation conditions.
KTZ uses cast-iron motor and pump bodies, a high-chrome-alloy semi-open impeller and a ductile-iron inlet/wear plate. LH uses hard cast-iron motor and pump bodies, a high-chrome-alloy impeller and a ductile-iron diffuser. Mechanical-seal materials depend on the family and model.
Water temperature up to 40 °C. Maximum water depth is 25 m for KTZ and 30 m for LH in their respective overviews. Confirm the applicable family, model and electrical data before selection.
The KTZ overview specifies a high-chrome-alloy semi-open impeller matched with a ductile-iron wear plate. Suitability still depends on the actual liquid and selected model.
The catalogue lists civil engineering, mines and quarries, sewage treatment plants and general pumping. Match the actual drainage duty to the selected pump rather than treating all listed duties as identical.

Choose the pump by the liquid, required flow and total head, electrical supply and installation conditions.
WC combines a submersible sewage pump with a cutter impeller and ring. The cutting assembly reduces fibrous material before it enters the discharge path. The catalogue covers two-pole and four-pole constructions for wastewater and sewage duties where a standard drainage impeller may be more prone to obstruction.

FC is a light sewage range with a closed single-channel impeller. Its catalogue covers clean to slightly dirty water and lists the solids passage for each model. Stainless steel construction and single-phase or three-phase versions make it a distinct series from the larger FC stainless steel wastewater catalogue.

FC Inox is the separate FC wastewater catalogue with a double-channel impeller and stainless steel wetted parts. Its stated applications span water exchange, drainage and filtration in agricultural and landscape settings. The model range and hydraulic data differ from the light FC catalogue and should be read independently.
