The Lowara S.p.A. research laboratories have developed anoriginal method for detecting wear through the use of fluidscontaining abrasive particles. When tested after 100 hours ofoperation, pumps with traditional coatings reveal a high degreeof wear. DIWA, thanks to its novel coating, shows no sign ofabrasion. The pump’s characteristic curves and performanceremain unaltered for a period approximately 5 times longer thanpumps with traditional coatings.

DRIVELUB SEAL SYSTEM

The electric motor is protected from ingress by a doubleseal system with oil chamber.

A V-ring (A) made of nitrile rubber adheres like a suctioncup to the upper surface and constitutes a first efficientbarrier that prevents solid particles from coming intocontact with the mechanical seal.

The mechanical seal (B) made of silicon carbide (SICSEAL) is extremely resistant to abrasion thanks to itsexceptional hardness.

The second seal is a lip one (C). It is continuouslylubricated thanks to the rotation of the mechanical sealspring which drives up the oil (ESSO MARCOL 82)conveyed by the pipe (D).

SubmersibleElectricPump for Solids-ladenWastewater

DL Series

The DL series electric pumps come with single-channel orVortex impeller (DLV), and are designed to handle solids-laden wastewater, with up to 22 m head and 42 m3/hcapacity.0.6 kW to 1.5 kW rated power.Solids handled up to 50 mm in diameter.

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 submergedpump.25°C with partiallysubmerged pump.

• Passes solids up to:45 mm (DL 806, 906,Vortex).50 mm (DL 1096, 1256,DLV 1006, 1156).

• Squirrel cage motor in a dielectricnon-toxic oil bath, which ensuresthe lubrication of the ball bearingsand more efficient cooling.

• Class F insulation.• 2-pole (0.6 to 1.5 kW) motors.• Mechanical seal protected by

sand labyrinth.• Versions:

Single-phase 220 V 60 HzThree-phase 220 or 380 V60 Hz.Other voltages available on request.Overload protection to be providedby the user (in the control panel).

• 5-metre cable for 2-pole DL-DLV• Pre-assembled float available on

request for single-phase versions(DL…CG, DLV…CG).

1) Le perdite di carico nelle curve sono soltanto quelle dovute alla contrazione dei filetti liquidi per cambiamento di direzione: lo sviluppo delle curve deve quindiessere compreso nella lunghezza della tubazione.

2) Le perdite di carico nelle valvole e saracinesche sono state determinate in base a prove pratiche.

1) Flow resistance in bends is due to the contraction of the liquid threads resulting from the change of direction: the development of the bends must there-fore be included in the length of the pipeline.

2) Flow resistance in valves and gates was determined on the basis of practical tests.
