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 catalog drawing marks 147, 83 and 35 mm vertically but prints no overall height for this model, so the total height is to be confirmed with the factory.

03
Water and electricity separation: the electrical chamber is isolated from the collection tank
04
Anti-winding protective structure in the impeller path
05
All-stainless steel movement, shaft and impeller assembly
06
High head, large flow and low noise, below 45 dB across the range
07

05Installation

Installation conditions

WL300B dimension drawing from the 2026 catalog — Dimension drawing of the WL300B, cropped from 2026 English catalog, p. 11.

Installed where drainage to the sewer cannot rely on gravity; the unit collects toilet, shower, basin and washing machine discharge and pumps it to the main drain.
The inlet must sit above the start level printed for the model, because the float switches the pump on at that height.
The motor and electrical parts sit in a chamber separated from the collection tank, and the enclosure class printed for the model applies to the unit.

06Fit

Where it fits, and where it does not

Suited to

Basement toilets, showers and utility sinks
Kitchen and laundry discharge where solids may be present
Renovation projects without gravity drainage to the sewer

Check before selection

Discharge line length, vertical lift and solids content must be checked against the published flow and head curve before selection. A maximum water temperature is printed for the WL550A only; the other WL models do not list one.
