Product Specifications

Technical details and manufacturing context for Precision Beverage Flow Metering Pump Head

Definition
This precision-engineered positive displacement pump head is designed for non-alcoholic beverage manufacturing lines. It ensures accurate volumetric dosing of syrups, concentrates, flavorings, and additives during blending and mixing processes. The pump head maintains consistent flow rates regardless of viscosity changes and pressure variations in the production system. It is engineered for clean-in-place (CIP) compatibility and meets food-grade hygiene requirements for beverage production environments.

The pump head operates on a rotating lobe or gear mechanism, creating fixed-volume chambers that trap and transfer liquid with minimal pulsation and high repeatability. The positive displacement design ensures consistent volumetric output per revolution, independent of system pressure variations. This makes it suitable for precise dosing applications where accuracy is critical.

Key parameters include an adjustable flow rate range of 0.5–50 L/h, dosing accuracy of ±0.5%, maximum operating pressure of 1.6 bar, and temperature range of -10 to 80 °C. Port connections are DN15–DN25 (DIN 11851), and internal surface roughness is Ra ≤ 0.8 (ISO 4287). Stroke length is adjustable from 5–20 mm, with stroke frequency from 10–120 min⁻¹. Power supply is 24 V DC ±10% (optional 230 V AC with converter), with power consumption ≤ 60 W at maximum stroke and pressure. The unit has an IP65 ingress protection rating (IEC 60529). Wetted materials are 316L stainless steel and PTFE (ASTM A240). Weight ranges from 5–8 kg depending on port size and options.

All listed values are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application. Standards mentioned are procurement references, not proof of certification or compliance.
Working Principle
The pump head uses a rotating lobe or gear mechanism to create fixed-volume chambers. As the rotors turn, liquid is trapped in these chambers and transferred from inlet to outlet. The positive displacement action ensures that each revolution delivers a consistent volume, regardless of system pressure. This design minimizes pulsation and provides high repeatability, making it ideal for precise dosing of beverage ingredients. The flow rate can be adjusted by varying the stroke length or frequency, allowing fine control over dosing volumes.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Cavitation damage
Cause: Insufficient net positive suction head (NPSH) leading to vapor bubble formation and implosion on pump surfaces
Wear and clearance degradation
Cause: Abrasive particles in beverage fluid causing erosion of precision components and loss of metering accuracy
Maintenance Indicators
  • Audible knocking or rattling sounds during operation indicating cavitation or mechanical wear
  • Visible fluid leakage around pump head seals or inconsistent flow output during calibration checks
Engineering Tips
  • Implement strict filtration upstream to remove particulates and maintain fluid cleanliness below 10 microns
  • Ensure proper NPSH margins through adequate suction line design and temperature control to prevent cavitation

Frequently Asked Questions

What is the flow rate range of this pump head?

The adjustable flow rate range is 0.5–50 L/h. However, the actual achievable flow rate depends on the specific model, stroke length, and stroke frequency settings. Always verify with the manufacturer for your application.

What materials are used for wetted parts?

The wetted materials are 316L stainless steel and PTFE, as listed in the reference data. These materials are commonly used in food-grade applications, but you should confirm compatibility with your specific ingredients and cleaning agents.

Is this pump head suitable for clean-in-place (CIP) procedures?

The pump head is engineered for CIP compatibility, meaning it can be cleaned without disassembly. However, the specific CIP parameters (temperature, chemical concentration, flow rate) must be validated with the manufacturer to ensure effective cleaning and material compatibility.

What is the maximum operating pressure?

The maximum operating pressure is 1.6 bar. This is a reference value; the actual pressure rating may vary with the model and installation. Always check the technical datasheet and consult the supplier.
