Page 3: Introduction Of The 4Hs Submersible Pumps Range
1. Introduction of the 4HS submersible pumps range 4HS is a 4” high speed centrifugal submersible pump for clean water composed by: high speed three phase asynchronous motor with wet rotor and canned type resin filled stator. Built-in inverter on board driven by a dedicated control module (CM) positioned outside the well. -

To make the junction is necessary to follow carefully the instructions inside the kit. At the time of joining and electrical connection is essential to maintain the correspondence between the signal cables. After cable joining and placed the pump in the well you must perform, before connecting to the CM, a test of insulation: join together the two power cables and, applying a voltage of 500V, an insulation resistance from the ground higher than 100 Mohm must be verified. -

Page 11: Pressure Tank
8.1 Pressure tank Installation of a pressure tank in the hydraulic system is recommended to compensate leakage of water in the system (or during minimum water demand) and to avoid continuous start/stop cycling of the pump (check the appendix for more information). Selecting the proper volume and pre-charge pressure of the tank is very important;... -

To stabilize the pressure control operated by the CM module, it is suggested to put the pressure sensor near the well exit, after the check valve. Pressure sensor and power cables can be close but it is suggested to use a shield cable connecting the shield to the sensor ground pin. -
