Submersible Electric Pump for Solids-laden Wastewater DL Series

Submersible
Electric Pump
for
Solids-laden
Wastewater
DL Series
The DL series electric pumps come with single-channel
or Vortex impeller (DLV), and are designed to handle
solids-laden wastewater, with up to 20 m head and 100
m 3 /h capacity.
0.6 kW (0.8 HP) to 4 kW (5.5 HP) rated power.
Solids handled up to 65 mm in diameter.
● Versions:
Single-phase 220-230 V 50 Hz,
with built-in thermal protector and
capacitor box with on/off switch.
Three-phase 220-240 or 380-415
V 50 Hz.
Overload protection to be provided
by the user (in the control panel).
● 5-metre cable for 2-pole DL-DLV
and 8-metre cable for 4-pole DL-
DLV.
● 60 Hz versions are available on
request.
● Pre-assembled float available on
request for single-phase versions
(DL…CG, DLV…CG).
TABLE OF MATERIALS
APPLICATIONS
● Pumping of sewage with
suspended solids and filaments.
● Emptying of sumps, septic tanks
and wastewater discharge tanks.
● Draining of flooded excavations
and marshy ground.
SPECIFICATIONS
● Maximum immersion depth: 5 m.
● Maximum temperature of
pumped liquid:
50°C with fully submerged
pump.
25°C with partially submerged
pump.
● Passes solids up to:
45 mm (DL 80, 90, 105,
Minivortex, Vortex).
50 mm (DL 109, 125, 160,
DLV 100, 115).
60 mm (DL 180, 200).
65 mm (DLV 120, 140, 160).
● Squirrel cage motor in a dielectric
non-toxic oil bath, which ensures
the lubrication of the ball bearings
and more efficient cooling.
● Class F insulation.
● 2-pole (0.6 to 1.5 kW) and 4-pole
(1.8 to 4 kW) motors.
● Mechanical seal protected by
sand labyrinth.

LIFTING AND LOWERING DEVICE
Used for pump inspection and maintenance without
going down the well.
It consists of a support foot with built-in delivery elbow,
a sliding adaptor and a bracket for fastening the
guide tubes (tubes not included).
Two models are available:
• DS 3 for DL 160-180-200 and DLV 120, 140, 150
pumps.
• DS 2 for DL 109-125, DLV 100-115 and DL 80-90-
105 MINIVORTEX, VORTEX pumps with flange.
