The new range of \u2018GQS\u2019 pumps are available alongside the \u2018GQV\u2019 range, as part of the submersible drainage series.<\/p>\n
The GQS pumps have the following construction features:<\/p>\n
\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Double mechanical shaft seal with oil chamber which separates the motor from the water and provides further protection against accidental dry running.<\/p>\n
\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Triple impregnation humidity-proof winding.<\/p>\n
\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Relief valve, which allows air release around the impeller and ensures\u00a0 proper priming of the pump even after long periods at standstill.<\/p>\n
\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Free flow (vortex) impeller is particularly suitable for liquids containing solids up to 50 mm grain size, with a special epoxy treatment for greater protection against corrosion.<\/p>\n
\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Pump casing with G 2\u201d vertical delivery port, for installation in small spaces, without the need for an elbow. The pump casing is also with the special epoxy treatment and external paint for increased protection against corrosion.<\/p>\n
The pumps are available with total heads to 15 m and maximum flow rate up to 600 l\/min, the motors are available in three-phase and in the single-phase versions with single phase featuring an easy inspection capacitor, thermal protector and incorporated float switch.<\/p>\n\n\t\t
