ZIEGLER Centrifugal fire pumps in modular system

The proven ZIEGLER pumps are not only available in various performance sizes but depending on quantity and position they also can be provided with different delivery outlets, with automatic switching and pressure control as well as with various foam proportioning systems.

The demand for an extinguishing technology keeping the secondary water damages as small as possible will be met increasingly by sophisticated, electronic systems. The three-stage ZIEGLER high-pressure pump proven since almost 50 years and continuously developed will be switched on via an electro-magnetic coupling of the running normal pressure pump if required. Its impellers are fixed on an own pump shaft, thus they will not run along with at sole operation of the normal pressure pump.

This allows on the one hand an extremely compact design and on the other hand the wear will be reduced considerably.

All ZIEGLER pumps are prepared suitably for relatively easy retrofit with a highpressure pump. If the connection line from the normal pressure pump to the highpressure pump will be opened, the electro-magnetic coupling will be actuated simultaneously. Then, the delivery outlet to the high-pressure reel or the corresponding high-pressure outlet will be opened.

A thermal discharge line to the tank or at equipment with a pump proportioner to the outside prevents an overheating at interruption of the water delivery. Optionally, an additional warning buzzer is available.

The following operation modes are possible:

  • pure normal pressure pump operation (high-pressure pump stopped)
  • pure high-pressure operation (normal pressure pump in circulation only runs for supply of the high pressure pump)
  • combined pump operation (normal pressure and high pressure pump are running at the same time)
