Ideal for the automatic domestic water supply and service water utilization in your house and garden

The electronic pressure switch TDP DS from Trotec is the reliable solution for the automatic control of deep well pumps, garden pumps, centrifugal pumps or water pumps without an individual mains plug – perfect, for instance, for watering the garden, implementing the domestic water supply, water delivery, draining quantities of water from a pool, or for carrying out cleaning work.

Provides for constant water pressure in the pipe system

The compact Trotec pressure switch is installed between your pump and the consumer connected (e.g. tap or garden hose) and the water delivery takes place automatically without manual switch-on and switch-off of the pump. In the pipe system connected the pressure switch ensures a constant water pressure for garden irrigation or domestic water supply. The pressure switch constantly monitors the pressure in the pipe. When the pressure drops, the device switches on automatically and re-establishes the pressure. When the pipe pressure is reached again, the pump control switches off automatically. In this way, the pump is preserved and its lifetime is extended. Both the water inlet and the water outlet are provided with an external thread with a diameter of 1". This makes the pressure switch compatible with common connections of pumps, hoses or tubes.

The solutions for pumps without a mains plug

The pressure switch is equipped with an open cable end and a mains plug. The power supply of the pump connected is implemented via the 1,100 W pressure switch TDP DS. For this purpose, the mains cable of your pump or of the external control box must be connected to the open cable end of the pressure switch. Note: Please note that the connection of the power supply should only be carried out by trained specialist staff. When the pressure switch has been connected to the pump via mains cable and integrated into the pipe system, you just have to connect the mains plug of the pressure switch to your domestic socket. Your water pump is now supplied with power via the pressure switch and automatically regulated by the TDP DS without requiring any maintenance.

The TDP DS turns your water pump into a domestic water supply system

The pressure switch TDP DS is not only the ideal solution for the use in the garden –you can also use this automatic pump control to upgrade your already existing water pump to a domestic water supply system which will then make it possible for you to use service water, for example for flushing the toilet, operating the washing machine or for working the shower. The electronic pressure switch provides for a constant water pressure in the pipe and protects the pump connected against damage from running dry, water hammers or overheating. The convenient and compact Trotec pressure switch is designed for a maximum working pressure of 10 bar. The current water pressure in bar can be read off from its integrated pressure gauge. The robust plastic housing is protected against splash water from all sides as per IP54 type of protection. The TDP DS matches almost all common pump systems without an individual pressure switch and without mains plug. Furthermore it is the ideal supplement for the Trotec's deep well pumps of the TDP series and the Trotec garden pumps of the TGP series.

Including backflow stop

The electronic pressure switch TDP DS comes equipped with a non-return valve that prevents the backflow of water and protects the pump from pressure shocks and pressure surge effects. The integrated backflow stop permits the water delivered to only flow into one direction in the pipe system connected.

By the pressure of the flowing water the closing element of the swing check valve is opened. When the pump is switched off and the water pressure drops, the remaining water in the hose presses the shut-off element into the opposite direction, closes the outlet and in this way prevents the water to keep flowing. 

Various applications in your home or garden

The pressure switch TDP DS from Trotec is for example ideal for the following applications:

• Garden irrigation via hose, micro-drip system or sprinkler
• Allows for refitting your pump to a domestic water supply system for providing service water to flush toilets and work washing machines or showers
• Delivery of water from wells, ponds, streams, cisterns or basins
• Draining swimming pools, garden ponds or rain barrels
• Washing the car or cleaning using a high-pressure cleaner 

Whatever your application may be – with the electronic pressure switch TDP DS from Trotec you benefit from convenient and reliable water pressure regulation without having to switch your pump on and off manually every time.
