TREVOLI - CMB-SP 3-47 - Stainless Steel Multistage Water Pump with Watertech Evo Variable Speed Controller

CMB-SP 3-47E with Watertech Presscontrol Evo-Variable Speed Controller

This pump is ideal for domestic water supply, providing adequate pressure for a small to medium single or double level home supporting up to 6 taps running at one time. Fitted with an electronic automatic constant pressure control system (provides constant pressure at constant flow) Starts automatically when the tap is turned on and Stops automatically when the last tap is turned off, Operating constantly from low flow to full flow.

Recommendation:  A pressure tank extends pump life, stores energy, reduces noise, reduces pump starts and protects against heat expansion, see drop-down menu.
A free three-way tee is provided with any pump and pressure tank combination.

Watertech Presscontrol Evo-Variable Speed Controller

The Watertech Presscontrol Evo is a variable frequency drive controller. It is designed to vary the number of motor revolutions of the pump depending on the water withdrawal by the system in order to maintain constant pressure and flow. Presscontrol Evo allows the user to adjust the system pressure and the pump restart pressure. It also stops the pump in case of water shortage and protects it from dry running. Presscontrol Evo comes equipped with automatic restart in case of failure and an anti-jamming function. The features of this controller mean it’s extremely energy efficient. The Presscontrol Evo can be installed on above ground and submersible pumps.

Technical Features: 

* Frequency: 50 / 60 Hz
* Adjustable system pressure 2- 12 Bar
* Adjustable cut-in pressure 1- 11 Bar
* Maximum operating temperature -60 °C
* Maximum Bar Pressure-16 Bar
* Minimum Flow Rate- 1 lpm
* IP65

Automatic Restart & Anti-Jamming Function: 

In case of stopping due to a water shortage, the device will automatically make 10 double attempts to rearm over the 24 hours following the failure, each lasting approximately 5 seconds to allow, if possible, the pump and the system to reload. The user can try to rearm the device at any time by pressing the Restart button. If for any reason the pump remains idle for 24 consecutive hours, the device will carry.

Installation & Start Up

Install the device in vertical position directly on the pump or between the pump and the first tap. Make all electrical connections, give power and wait a few seconds. When the set-up is completed the factory-set current and pressure values will appear on the display (CURRENT 1,5 A - SYSTEM PRESSURE 3,0 bar - CUT-IN PRESSURE 1,5 bar), the Current display starts blinking and the real pressure value of the system appears on the Pressure display. Set the current absorbed by the motor indicated on its nameplate. In order to adapt the system to the desired operation, it may be necessary to set different pressure values from those set by the factory: system pressure 3 bar - cut-in pressure 1,5 bar. Once the values are set, press the button ON (green LED on) to start. When the pump is running, the real value of the current absorbed by the motor appears on the Current display. In the event of a temporary blackout, the device automatically resets itself when electricity returns.
