| New NEPTUNE line upgrade  Nilfisk-ALTO announced the upgrade of the successful NEPTUNE medium and premium range lines of hot water professional pressure washers. The new NEPTUNE 4 FA, 5 FA and 7 FA line will come equipped with a hot water version of the new NA5 pump. This pump, already present in a cold water version on the POSEIDON 5, is a 3 ceramic piston wobble disc pump, driven by a 1450 rpm motor. In addition, the hot water models will be equipped with a flow activated system – a further development on the old 02 and C3 KEW systems. The flow activated system uses the movement of water in order to generate the start and stop impulses to the motor. Compared to the pressure activated system, the new solution offers several advantages:• Absence of stand-by pressure in the hose, gun and lance during by-pass. Hoses etc become more maniable, easy to move and safe. • Low sensitivity to leaks in equipment, components or piping. Leaks that would generate motor start-stops on pressure activated systems will not cause these problems on flow activated systems – thus preserving motor life. As on the pressure activated systems, pump head is not under pressure and simplicity and ease of service are good. The terminology "FA" in the product name will indicate that the unit is equipped with a flow activated system. write your comments about the article :: © 2010 Construction News :: home page |
