Product Specifications

Technical details and manufacturing context for Precision Dosing Pump

Definition

The Precision Dosing Pump is a component used in beverage manufacturing to transfer syrup or concentrate from a holding tank to the point of final mixing or dispensing. It ensures the correct ratio of syrup to diluent, such as water or carbonated water, is maintained for consistent product quality. The pump operates on a positive displacement principle, using mechanisms like piston, diaphragm, or peristaltic action to move a fixed volume of fluid per cycle. The volume per stroke and stroke frequency are controlled by an integrated or external control system to achieve the desired flow rate and dosing accuracy. Key parameters include a flow rate range of 0.5–50 L/h, adjustable via stroke length and frequency, and an accuracy of ±0.5% with repeatability within ±0.25%. Operating pressure is specified as 1.0–1.6 MPa, with a maximum discharge pressure of 2.5 MPa to avoid diaphragm damage. The temperature range for media is -10 to 80°C, with ambient up to 40°C. Viscosity range is 1–1000 mPa·s, requiring derating for higher viscosities. Power supply is 220–240 V AC, 50/60 Hz, single phase, with power consumption of 0.25–0.75 kW depending on motor size. Ingress protection is IP54–IP65 per IEC 60529, suitable for washdown environments. Wetted materials include 316L stainless steel per ASTM A240, with optional PTFE diaphragm. Weight ranges from 15–30 kg, and approximate dimensions are 400×250×300 mm. These values are reference ranges and must be verified for the specific model and application. The pump is designed for integration into an Integrated Beverage Syrup Preparation and Dosing System, where it plays a critical role in maintaining product consistency. It is not a standalone product but a component that requires proper selection, installation, and calibration. Always confirm model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The pump uses a positive displacement mechanism, such as a piston, diaphragm, or peristaltic action, to move a fixed, precisely controlled volume of fluid per cycle. The volume per stroke and the stroke frequency are controlled by an integrated or external control system to achieve the desired total flow rate and dosing accuracy. This ensures accurate and repeatable delivery of syrup or concentrate.

Common Materials

Stainless Steel (wetted parts), Food-grade elastomers (seals, diaphragms), Engineering plastics (housing)
