Automatic pump control with plug & play:
Just connect it and you're done!

Whether you need a solution for garden irrigation, domestic water supply, water pumping, draining quantities of water from a swimming pool or for doing cleaning work – the electronic pressure switch TDP DSP from Trotec is the convenient and reliable plug &-play solution for the automatic control of garden pumps, deep well pumps, centrifugal pumps or water pumps. 

For constant water pressure in the pipe system

Simply install the compact pressure switch between the 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 the domestic water supply. The line pressure is constantly monitored by the pressure switch. When the pressure drops, the devices switches on automatically and re-establishes the pressure again. 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. The two inlet and outlet nozzles at the pressure switch are equipped with 1“ external threads and therefore perfectly match conventional pump, hose or pipe connections.

Plug & play – power supply of the pump via the power socket in the pressure switch

The power supply of the pump is also implemented via the 1,100 W pressure switch TDP DSP. Just connect the mains plug of your pump to the 230 V power socket integrated into the pressure switch. If you connect the mains plug of the pressure switch to your domestic socket now, the water pump is automatically supplied with power and regulated in a maintenance-free fashion every time the consumer is opened and closed. The electrical connection of the pump to the pressure switch does not require the help of specialist staff.

With the TDP DSP you turn your water pump into a domestic water supply system

The TDP DSP 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 pressure switch TDP DSP provides for a constant water pressure in the pipe and protects the pump connected against damage by running dry, back-pressure effects and overheating. The convenient pressure switch is designed for a maximum working pressure of 10 bar. The current water pressure in bar can be read off at the integrated pressure gauge. The robust plastic housing is protected against splash water and dust from all sides as per IP65 type of protection. The TDP DSP almost matches all conventional pump systems without an individual pressure switch and is furthermore the ideal supplement for the Trotec garden pumps of the TGP series and the Trotec's deep well pumps of the TDP series.

Including a backflow stop

The electronic pressure switch TDP DSP is equipped with a non-return valve. This prevents the backflow of water and offers protection against pressure shocks and water hammers. The backflow stop mechanism permits the water delivered to only flow into one direction in the pipe system.

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

Diverse application possibilities

The electronic pressure switch TDP DSP is especially suitable for the following applications:

• garden irrigation with a hose, sprinkler, micro-drip system
• Allows for refitting your pump to a domestic water supply system for providing service water to flush toilets and work washing machines or showers
• Water delivery from a well, a pond, a stream, a reservoir or a cistern
• Draining swimming pools, garden ponds or rain barrels
• Cleaning work using a high-pressure cleaner or washing the car

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