CDLF / Vertical pressure boosting and process water
CDLF is a vertical, non-self-priming multistage centrifugal series for water supply and pressure duties. Its staged hydraulic design supports different flow and head combinations, with component materials specified separately for each subrange.
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
The CDLF series uses a standard motor coupled to a vertical multistage pump shaft. Inlet and outlet are at the base on one level. The catalogue covers filtration and water transfer, building pressure boosting, industrial cleaning, cooling and water-treatment systems.
Component materials vary by subrange: CDLF 2/4 list a cast-iron pump head and AISI 304 base plate; CDLF 8/12/16/20 list a cast-iron head and base plate; CDLF 32/42 list an AISI 304 head and cast-iron base plate. The catalogue limits the pumped liquid to thin, clean, non-flammable and non-explosive media without solid particles or fibres. Select the exact flow-head curve, temperature version, materials, pressure limit and electrical supply for the installation.
Material schedules differ by subrange. CDLF 2/4 specify a cast-iron pump head and AISI 304 base plate; CDLF 8/12/16/20 specify a cast-iron head and base plate; CDLF 32/42 specify an AISI 304 pump head and cast-iron base plate. The tables list AISI 304 impellers and diffusers, with shaft material options depending on the subrange. Confirm the exact model schedule.
Thin, clean, non-flammable and non-explosive liquids without solid particles or fibers. Normal type: −15 to 70 °C; hot-water type: −15 to 120 °C. Ambient temperature up to 40 °C and altitude up to 1000 m.
The operating conditions specify thin, clean liquid without solid particles or fibers. Choose a different suitable construction for solids-bearing duty.
Use the selected temperature version. The normal type is listed to 70 °C and the hot-water type to 120 °C; confirm the configuration before ordering.

IRG is a single-suction centrifugal pump range for clean-water service. Its catalogue spans multiple discharge sizes and motor speeds and describes vertical and horizontal installation designs. Cast-iron casing construction and model-specific impeller options make it a separate choice from the CDLF multistage family.
