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.
