DAB NKM-G 40-250/260/A/BAQE/3/4 – standardized monoblock centrifugal pump, cast iron impeller, 3 kW
Code: 1D2411B7XProduct detailed description
DAB NKM-G 40-250/260/A/BAQE/3/4 (code 1D2411B7X) is a single-stage standard pump in a compact monoblock design with a volute casing and a bronze intermediate section. The bronze impeller is dynamically balanced and axial forces are balanced by relief holes. The pump is suitable for water transport in industry, hot water circulation in central heating, air conditioning and cooling systems, agricultural irrigation and pumping stations.
Motor
The standard closed three-phase asynchronous motor MEC 100 L in form B5, air-cooled, is four-pole (1450 1/min). The rated power P2 is 3 kW (4 HP), supply voltage 400 V in a triangle connection and rated current 6.8 A. The shaft runs in robust ball bearings, protection class IP55, insulation class F. The motor must be protected against overload.
Hydraulics and connection
At zero flow, the pump achieves 23.3 m, at 12 m³/h 22.8 m, at 24 m³/h 20.8 m and at 30 m³/h 19 m. The suction flange has a nominal diameter DN 65, the discharge flange DN 40, flanges PN 16 according to DIN 2533. The pump shaft is made of stainless steel AISI 304 and the standard mechanical seal is a combination of carbon / silicon carbide / EPDM. Weight is 89 kg.
Conditions of use
Liquid without solid and abrasive substances, non-aggressive, non-viscous, non-crystallizing and chemically neutral, with a temperature of −10 to +140 °C. Maximum operating pressure 16 bar, ambient temperature up to +40 °C, installation in a horizontal position. Installation and electrical connection should be carried out by a qualified person.
