Reliability and fast operational readiness are required for dewatering applications on construction sites. The HOMA construction box combines exactly these two components. The robust plastic box can supplement the basic equipment of the construction site vehicle ready for connection. The construction box is equipped with a new HBP 503 construction pump, which can be used universally and provides constant power even when exposed to abrasive liquids. Thanks to the 10 m connection cable with power plug and the 10 m fabric hose with C-coupling, the construction box is ready for immediate use. The switchgear included in the scope of delivery can be used to easily switch between manual and automatic switching. In this way, the float circuit can be bypassed, for example, to pump the excavation pit even deeper.

Stationary or transportable. Design with float circuit as automatic dirty water pump with water level-dependent operating control.
