This new series of submersible pumps is fitted with a patented anti-seize system (ensuring pump operation, even after being left idle for long periods), and an oversized motor in a biodegradable, non-toxic, oil bath.

PUMP INSTALLATION AND APPLICATIONS

SK pumps should be used in clean water not containing abrasive substances.

THEIR DEPENDABILITY AND ECONOMICAL NATURE MAKE THEM PARTICULARLY SUITABLE FOR DOMESTIC USE. THEY ARE PARTICULARLY SUITED TO WATER SUPPLY APPLICATIONS (IN CONJUNCTION WITH A PRESSURE VESSEL OR “EASYPRESS” CONTROLLER) AND FOR IRRIGATING GARDENS etc.

SK pumps can be installed in wells with a diameter of no less for 4 inches (4SK) The pump is lowered into the well by means of the delivery pipe until it is completely immersed (min. 50cm), and at least one meter from the bottom of the well) Care should be taken to ensure that the pump remains submerged, as pump operation may cause the level of the liquid in the well to fall. It is advisable to secure the pump using a stainless steel or nylon cable connected to the special holes on the discharge head.
