Pipe and Sewage Protection

To prevent water hammering of pipes during start and stop of pumps, the super-slim motorstarter Christian P4.0 is the solution. The topic is essential for all pipe systems that include flexible tubes, which are connected

to the main pipe via snap in fittings/couplings. This arrangement is typically used in temporary water supplies, green houses, dosing systems for pools, and agricultural applications.

Christian P-4.0 with soft start and soft stop functions increases the water pressure in the pipe in a controlled way. The pump does not expose the pipes to the water pressure immediately during the startup process.

In the event of stopping the pump, check valves will not shut immediate due to the reverse pressure of the water and avoid a pressure peak. Soft stopping enables the check valve to shut moderately fast without

any hammering effects to occur and also increases the life-span of the valves.
