KSB ETABLOC-GN 040-160/074 G01 Close-Coupled Centrifugal Pump
1. Product Overview
ETABLOC-GN 040-160/074 G01 is a KSB Etabloc-series standardized single-stage, single-suction close-coupled (monoblock) volute pump, with hydraulic ratings and main dimensions to EN 733 (formerly DIN 24255). Unlike the long-coupled Etanorm, the Etabloc casing mounts directly onto the motor flange — pump and motor share one shaft with no coupling — giving a compact footprint.
In the model: GN = material/design version; 040 = nominal discharge DN40 (suction DN65 per EN 733); 160 = nominal impeller diameter 160 mm; /074 = impeller trimmed to duty / configuration code; G01 = design version. On a 2-pole motor (~2900 r/min) this size typically delivers Q ≈ 15–25 m³/h at H ≈ 20–30 m, with high efficiency and smooth running.
It handles clean water, cooling/chilled water and similar fluids; for thermal oil use the Etabloc SYT version.

7. FAQ
Q1: What is ETABLOC-GN 040-160/074 G01?
A: A KSB Etabloc close-coupled single-stage, single-suction standard pump, EN 733, DN40 discharge, 160 mm impeller.
Q2: Etabloc vs Etanorm?
A: Etabloc is compact, casing bolted to the motor flange (no coupling); Etanorm is long-coupled with a bearing bracket, allowing pump service without moving the motor.
Q3: What do the numbers mean?
A: 040 = discharge DN40; 160 = nominal impeller diameter 160 mm; /074 = trim/config code; G01 = design version.
Q4: Flow and head?
A: At 2-pole (~2900 r/min), typically Q=15–25 m³/h, H=20–30 m; see selection curve for the exact point.
Q5: Max pressure/temperature?
A: Standard version up to 16 bar, fluid −30 to +140 °C.
Q6: What fluids?
A: Clean water, cooling/chilled water and similar fluids; use SYT for thermal oil. For motors/seals, please email us.
