GRUNDFOS NBG Horizontal In-line Single-Stage End-Suction Pump (Direct-Connect)
High-Efficiency and Energy-Saving Design
Utilizing an optimized impeller hydraulic model, the efficiency reaches up to 89.4% (2-stage model), meeting ISO 9906 Annex A standards and significantly reducing operating energy consumption.
Diverse configuration options
Suitable for various media needs, including cast iron and stainless steel.
Supports multiple flange standards (DIN/ANSI/JIS) and pressure ratings (PN10–PN40) to meet global installation specifications.
Options for standard or heavy-duty bearing brackets to accommodate varying load conditions.
Flexible Sealing Solutions
Standard configuration includes a cartridge mechanical seal, with optional dual-seal arrangement or packing seal (cast iron models only), ensuring reliable leak protection.
Shaft seal diameters range from 42 mm to 55 mm to suit diverse operating conditions.
Modular Structure Design
The pump body and motor are directly connected, reducing maintenance points and supporting quick disassembly (the minimum pull-back distance X of the bearing bracket is marked on the drawing).
Available with foot-mounted pump casings or baseplate mounting; compatible with horizontal or vertical piping layouts.
Extended performance range
Covering flow rates of 8-1400 m³/h, with a maximum head of 200m (2-pole model), and supporting 50Hz multi-pole speed control (2/4/6 poles).
New models are fully compatible with existing installation dimensions, simplifying system upgrades and retrofits.
Intelligent Compatibility
Supports variable frequency motor drive (built-in inverter option), adapts to IE2 energy efficiency motors, and has reserved sensor interfaces.
Stringent Standards Certification
Designed to meet EN 733 and ISO 2858 standards, with a pressure rating up to PN40 (stainless steel).
Typical application scenarios: industrial circulation systems, HVAC, water supply pressurization, heat exchange stations and other fields that require efficient and stable fluid delivery.
