Product catalog summary
Overview: This document outlines the technical specifications and features of DAB PUMPS' enbloc electric centrifugal pumps, which are suitable for applications such as heating, air conditioning, and industrial uses. These pumps are equipped with MCE/C inverters to ensure adaptable performance and maintain constant differential pressure.
Specifications: The pumps have a spiral single-stage body made of cast iron. Key components include an impeller and pump shaft made from cast iron and AISI 304 stainless steel, respectively. They operate within a speed range of 1450 - 2900 rpm and can handle liquid temperatures from -10°C to +140°C. The maximum operating pressure is 16 bar, with a protection rating of IP 55 and insulation class F.
Materials: Standard versions use cast iron for the pump body, support, and impeller, while the pump shaft is constructed from stainless steel. Mechanical seals are made from carbon/carborundum with EPDM O-rings.
Performance: These pumps are designed for clean, non-viscous, and chemically neutral liquids. They can be installed either horizontally or vertically, as long as the motor is positioned above the pump. Special versions are available for handling liquids other than water and for different voltages or frequencies.
Models and Electrical Data: The document details various models of the NKM-GE series, including their motor sizes, mechanical seals, and electrical requirements. The pumps are available in both single-phase and three-phase versions, with power ratings ranging from 0.25 kW to 15 kW.
Performance Curves: Performance curves for different models are included, showing flow rates, head, power consumption, and NPSH (Net Positive Suction Head) values. These curves are based on standard conditions with a kinematic viscosity of 1 mm²/s and a density of 1000 kg/m³.
Conclusion: DAB PUMPS' centrifugal pumps are versatile and efficient, making them suitable for a wide range of applications. They offer customizable options to meet specific system requirements, ensuring reliable and adaptable performance.
