Component Specifications

Definition
The pump block or housing is a precision-engineered structural component that serves as the main body of a high-pressure pump unit. It provides mounting surfaces, alignment features, and sealed chambers for pistons, valves, and bearings while withstanding extreme internal pressures and mechanical stresses. This component ensures proper fluid flow paths, maintains component alignment, and prevents leakage in demanding industrial applications.
Working Principle
The pump housing creates sealed pressure chambers where reciprocating or rotating pump elements generate hydraulic pressure. It directs fluid flow through precisely machined passages while providing structural integrity to contain high internal pressures (typically 100-700 bar). The housing maintains geometric stability under thermal expansion and mechanical loading to ensure consistent pump performance.
Materials
High-strength cast iron (GGG-40/50), ductile iron (EN-GJS-400-18/500-7), or forged steel (42CrMo4) with hardness 180-250 HB. Pressure-containing surfaces often have hardened coatings or liners for wear resistance.
Technical Parameters
  • Weight Range 5-50 kg depending on pump size
  • Surface Finish Ra 0.8-1.6 μm for sealing surfaces
  • Pressure Rating 100-700 bar
  • Temperature Range -20°C to 150°C
  • Flatness Tolerance 0.02 mm per 100 mm
  • Port Thread Standards SAE, BSPP, NPT
Standards
ISO 4401, DIN 24342, ISO 1219
