PUMP
The Grundfos SE1 pump range are high specification products for heavy duty pumping applications where reliability and ease of servicing are essential requirements. Particular uses are for pumping sewage and heavily polluted water in municipal, utility and industrial applications.
Featuring advanced technology design, the pumps utilise high efficiency semi-axial type channel impellers with excellent non-clogging performance and solid passing capability. Other notable features include a hermetically sealed cable entry to eliminate liquid penetration, cartridge type double mechanical seal for durability and ease of maintenance and a simple clamp coupling arrangement of the motor and pump units for easy disassembly.
The SE1 range is of unique modular design with standard motor units fitting several pump models. Also the hydraulic end is adaptable for submersible auto coupling, submerged free-standing or dry configurations by simply specifying the appropriate mounting components. Three basic models are stocked, though the range is extensive and different models are available to special order for specific requirements.
The pump end including impeller and pump housing are manufactured from cast iron, the stator housing from cast aluminium and the motor jacket, clamp and cable entry from stainless steel. 1 Om of Neoprene rubber drop cable is supplied as standards.
