Fire­fighting Equipment

Description

PDmatic is a Foam Proportioning System (DZA) that is completely mounted on JOHSTADT Vehicle Mounted Pumps. As the foaming pump is driven by the pump shaft of the Vehicle Mounted Pump, no additional electrical operating power is necessary.

All regulating parameters are measured contactless und hence wear-free. It is operated conventionally by buttons, by display or by CAN-bus interface. As the foam is fed on the pressure outlet no foaming agent comes in contact with the Vehicle Mounted Pump or the water tank. The pump can be flushed automatically.

Especially to be emphasised is the mixing either in normal (10/15 bar) or high pressure (40 bar). The foaming agent can be primed up to 1.5 m from an external source.
