The high pressure pump is a critical component of a high-pressure homogenizer, designed to pressurize fluid to extremely high levels, typically 100–2,000 bar, before forcing it through a narrow homogenization valve. This pump creates the necessary pressure differential that enables particle size reduction, cell disruption, and emulsion formation in various industrial applications. It operates on a positive displacement principle, typically using piston or plunger mechanisms. Multiple pistons work in sequence to provide continuous flow, drawing in fluid and compressing it to high pressures. The pressurized fluid is then directed to the homogenization valve, where a sudden pressure drop causes cavitation, shear forces, and impact that homogenize the material. The pump is available with materials such as stainless steel (316L), ceramic, and high-strength alloys, which are selected based on the fluid properties and application requirements. Key parameters include operating pressure (1.0–1.6 MPa), flow rate (5–50 m³/h), power rating (15–75 kW), voltage (380–690 V AC per IEC 60038), frequency (50–60 Hz per IEC 60038), maximum fluid temperature (80–120°C), ambient temperature (-20–40°C), ingress protection (IP54–IP65 per IEC 60529), pump efficiency (75–90% per ISO 9906), noise level (75–85 dB(A) per ISO 3744), weight (300–1500 kg), and dimensions (1200×800×1000 to 2500×1500×1800 mm). These values are reference ranges and must be verified for the specific model and application. The pump is used in industries such as food, pharmaceutical, chemical, and biotechnology for processes requiring high-pressure homogenization. It is essential to confirm model-specific values and standards with the legal manufacturer or supplier before procurement or installation.
