1. Introduction
Introdction
This data booklet deals with Grundfos SEG sewage
grinder pumps.
Fig. 1 SEG pumps
The SEG pumps are designed with a grinder system
which grinds solids into small pieces so that they can
be led away through pipes of a relatively small
diameter.
The pumps are made of wear-resistant materials, such
as cast iron and stainless steel. These materials
ensure reliable operation.
The pumps are available with motors of 2.0 hp and up
to 5.5 hp. All motors are 2-pole motors.
The nominal diameter of the pump outlet port is 1.5"
(40 mm) or 2.0" (50 mm).
The pumps are available for these installation types:
• submerged installation on auto-coupling systems
• submerged installation, free-standing.
Applications
The SEG pumps are ideal for use where gravity
sewage systems are not available. Examples include
small towns, farm areas, and areas with difficult
topography, such as rocky terrains with large
differences in levels, or any other area where a
pressurized system offers advantages.
Construction features
All pumps have the following features:
• cable connection to motor via plug
• watertight cable entry of corrosion-resistant
stainless steel with polyamide
• stainless steel clamp connection between motor
and pump
• cartridge shaft seal
• heavy-duty bearings greased for life
• patented grinder system ensuring extremely high
efficiency and reliable operation
• SmartTrim system enabling quick and easy impeller
clearance adjustment in order to maintain peak
performance
• thermal switches built into the motor windings
providing protection against overheating
• FM-approved motors for potentially explosive
environments
• moisture switches built into the motor.
