Caprari drn40t-400v 4.1kw electric pump

DR-TYPE ELECTRIC PUMPS

These are electric pumps of sturdy and durable construction suitable for severe use on construction sites and in all those cases of difficult working conditions due to the presence of sand, silt. Simple and periodic maintenance, facilitated by the rationality of construction, is a guarantee of prompt and safe intervention in case of need and consistent performance in ordinary use. Commonly used in construction and road construction sites, thanks to the special urethane rubber coating of the parts most subject to wear, they allow the pumping of water containing even abrasive substances. By performing a simple adjustment of the wear plate, the initial hydraulic characteristics can be restored. Should the wear be very pronounced, replacement of the affected parts is easy and quick to perform.

LIMITS OF USE

• - max. temperature of pumped liquid = 40°C;
• - max. immersion depth = 20 m; - DRN... minimum immersion depth = 457mm - PH of pumped liquid: 5 ÷ 8
• - supply voltages and relative permissible variation from rated voltage:
• - three-phase: 400 V ±10% (380-400-415) standard 230 V ±10% (220-230-240) on request
• - other voltages with ±5% on request - maximum unbalance allowed on the absorbed current: 5%
• - consult our technical offices in the presence of a density higher than 1 kg/dm3 and/or a viscosity higher than 1 mm2 /s (1 cSt)
• - the electric pump generates a sound pressure level below 70 dB(A).

INSTALLATION

The electric pump is installed in the sump and can be used:

• - connected to flexible piping - connected to rigid piping directly to the threaded delivery port
• - automatic control by means of special equipment is possible

CONSTRUCTION

• - open impeller with wear plate, nitrile rubber lining
• - double front mechanical seal - dry chamber motor with class F insulation, IP68 protection rating
• - stainless steel screws and nuts.
• - Thermal probes (for models ≥ 11kW where they are provided) The motor has thermal probes connected in series inserted in the stator winding. In case of overtemperature, they interrupt the power circuit.
