Sigma S2CAHM07120PVT Metering pump

• Precise chemical dosing in water treatment plants.
• Accurate additive injection in food and beverage production.
• Controlled dispensing of reagents in pharmaceutical processes.
• Metering of corrosive or viscous fluids in industrial manufacturing.

Typical flow rate

Metering pumps of this class typically offer adjustable flow rates, often ranging from a few millilitres per hour up to several hundred litres per hour, depending on the specific pump head and motor configuration.

Maximum discharge pressure

Units like this commonly operate at discharge pressures up to 10-16 bar, though higher pressure models are available for specific applications.

Power supply

This unit is listed as 0.25kW. Metering pumps typically require a standard industrial electrical supply, often 230V single-phase or 400V three-phase, 50Hz in the UK.

Materials of construction

For chemical compatibility, the wetted parts (pump head, diaphragm, valves) are commonly made from materials such as PVC, PP, PVDF, or stainless steel, depending on the intended fluid.

Control type

Metering pumps typically feature manual stroke length adjustment and often include options for external control signals (e.g., 4-20mA, pulse) for automated dosing.

Mounting

Units are commonly designed for base mounting or wall mounting, offering flexibility in installation within a process line.

• What types of liquids can this pump handle?

  Metering pumps are designed for a wide range of liquids, including corrosive chemicals, viscous fluids, and slurries, provided the wetted materials are compatible with the fluid being pumped. Buyers should verify material compatibility for their specific application.

• How accurate is a metering pump?

• What maintenance is typically required for a metering pump?

• Can this pump be integrated into an existing control system?

• Is this unit suitable for continuous operation?

Dispensing pumps are valued for accuracy and reliability in laboratory and pharmaceutical settings. Buyers typically prioritise consistent flow rates, ease of maintenance, and compatibility with various fluids. When purchasing used equipment, checking calibration history, wear on seals and tubing, and pump condition proves essential. Industry sentiment favours models from established manufacturers known for durability. Common strengths include repeatability, longevity with proper care, and cost-effectiveness compared to new alternatives. Verification of operational history significantly influences buyer confidence.
