Introduction
Introduction
This data booklet deals with Grundfos submersible
sewage pumps, types SL1 and SLV.
Fig. 1 SL1 and SLV pumps
The pumps are free-flow (SuperVortex) and single-
channel impeller pumps specifically designed for
pumping sewage and wastewater in a wide range of
municipal, private and industrial applications.
The pumps are made of resistant materials, such as
cast iron and stainless steel. These materials ensure a
proper operation.
The pumps are fitted with motors from 1.5 hp up to
15 hp (1.1 to 11 kW). The motors are either 2- or 4-pole
motors, depending on the motor size.
The free passage in the pumps is 2 to 4” (50 to
100 mm).
The pumps are available for:
• submerged installation on auto-coupling system
• submerged installation, free-standing.
Applications
Typical applications are transfer of liquids, such as:
• municipal wastewater
• wastewater with high content of fibres (SuperVortex
impeller)
• drainage and groundwater
• domestic wastewater
• industrial wastewater
• process and cooling water.
The pumps are ideal for the pumping of the above
liquids from for instance:
• municipal network pumping stations
• inlet pumping stations in wastewater treatment
plants
• primary clarification in wastewater treatment plants
• secondary clarification in wastewater treatment
plants
• stormwater pumping stations
• public buildings
• residential buildings
• factories/industry.
Overall construction features
• Cable entry as cable plug, made of corrosion-
resistant stainless steel with conductors embedded
in polyamide
• Power cable incorporating wires for thermal sensors
in the motor windings
• No extra cable required for sensors in pumps with
sensors
• Monitoring of operating conditions for pumps with
sensors
• Moisture detector for continuous monitoring of
motor enclosure and automatic cut-out in case of
leakage
• Heavy-duty bearings greased for life
• Built for variable frequency drive operation
• Smooth pump surface prevents dirt and impurities
from sticking to the pump
• Self-cleaning channel impeller with long vanes, thus
reducing risk of jamming or clogging, or Super-
Vortex impeller with high pumping efficiency and
less downtime
• Explosion-proof motors for potentially explosive
environments
• Motor in insulation class H (356 °F (180 °C),
enclosure class IP68 with thermal sensor in each
phase
• Temperature rise class A (1.5 to 8 hp) or class B (10
to 15 hp)
• Service-friendly design:
- clamp connection between motor and pump
- cartridge shaft seal
- cable connection to motor via plug.
• Motor built of highly efficient EFF1 components,
offering lower motor temperature and longer life.
