Port sizes above are transcribed from the dimension drawing of this model. Any field the catalog leaves blank is omitted rather than estimated, and the order-specific technical file confirms the final connection set.

The parameter table prints 840 × 535 × 539 mm while the dimension drawing on the same page marks a 840 × 720 mm footprint and 539 mm height; the final footprint is to be confirmed with the factory.

03Packing

Packing and container loading

The 2026 catalog prints packing tables for the WL range only. The DMJ170 is shipped as a station unit, so crate dimensions, gross weight and loading plan are issued with the quotation for the selected pump and control configuration.

Station ships as one unit with the pump, level control and tank assembled.
Crate dimensions and gross weight depend on the selected pump input and control configuration.
Container loading is planned per order rather than per unit.

03
Multiple pre-formed inlet ports in different directions for installation flexibility
04
Dual-level control combining pneumatic air-pressure sensing and a float switch
05
IP68 pump station with motor insulation class F on the DMJ25, DMJ90, DMJ170 and DMJ460
06
Free passage from 35 mm to 60 mm depending on the series

05Installation

Installation conditions

DMJ170 dimension drawing from the 2026 catalog — Dimension drawing and performance curve of the DMJ170, cropped from 2026 English catalog, p. 27.

DMJ170 buried installation diagram from the 2026 catalog — Installation diagram of the DMJ170, cropped from 2026 English catalog, p. 27.

Buried installation: the tank sits below ground and the pump chamber is reached for service from above, outside the stored volume.
Inlet ports are pre-formed in several directions, so the pipe run can enter from the side that suits the excavation.
Level control uses air-pressure sensing plus a float switch, and the station is limited to the starts per hour printed for the series.

06Fit

Where it fits, and where it does not

Suited to

Whole-building drainage below the main sewer level
Basement toilets and shower rooms in commercial buildings
Retrofit projects where a buried tank is the only option

Check before selection

Excavation depth, tank bedding and inlet invert levels must be checked on site before ordering, and the station is limited to the start-stop frequency printed for the series.
