4” VARIABLE SPEED SUBMERSIBLE PUMPS

4HS IS A RANGE OF 4” ELECTRIC SUBMERSIBLE PUMPS FOR WELL APPLICATIONS, FEATURING: Three-phase, water-filled, permanent magnet synchronous motor with encapsulated resin stator, fully constructed of AISI 304 stainless steel. Built-in integrated inverter controlled by CM control module. Multistage pump made of AISI 304 stainless steel. AN INVERTER ALLOWS 4HS TO: Change pump speed to maintain set-pressure regardless of water demand. Consequently the pump is operated only when and as needed without wasting energy, thereby extending pump life. Starts and stops pump gently, thus reducing peak...

TO SET UP THE SYSTEM IN A CONSTANT PRESSURE APPLICATION SIMPLY INSTALL THE 4HS PUMP, CONNECT THE CM CONTROL MODULE AND WIRE THE PRESSURE SENSOR. A small pressure tank is normally used to compensate for water loss while the pump is not running. The control module receives the pressure signal from the pressure transducers and varies pump speed to maintain a constant set pressure regardless of water demand. In addition to the constant pressure control, CM can also manage the following control modes: fixed frequency constant flow constant temperature 4HS pump Control Module No return valve...

UNMATCHED USER EXPERIENCE Thanks to the Nastec NOW app it is possible to communicate with all Nastec SMART Bluetooth® devices in order to: Monitor multiple operating parameters simultaneously on the wide, highdefinition colour screen of your smartphone or tablet. Develop programs, save them in the archive, copy them to other devices and share them among multiple users. Get energy consumption statistics and check the alarm log. The CM control module manages the operation of the pump from the surface, regulating its speed to maintain the desired pressure constant regardless of the water...

PREDICTIVE ANALYSIS AND REMOTE CONTROL Through predictive analysis conducted by the device during operation, it is possible to intervene before the problem occurs, minimizing intervention and repair costs. If the device is connected to the internet using the optional WiFi or GSM remote control kits, warning or alarm notifications can be sent via email to the relevant users. To achieve this, a quick configuration is all that is needed through the remo.nastec.eu portal. MODBUS RTU AND BACNET CONNECTIVITY AS STANDARD The device can be connected via RS485 serial port to external control systems...
