Typical flow rate

For this class of metering pump, flow rates commonly range from a few millilitres per hour up to several hundred litres per hour, depending on the specific model and application.

Typical discharge pressure

Units of this type are often designed to operate at discharge pressures typically up to 10-15 bar, suitable for various processing lines.

Power supply

Metering pumps commonly operate on standard industrial single-phase or three-phase supplies, with power ratings typically in the 0.18 kW to 0.75 kW range for smaller units.

Materials of construction

Wetted parts are typically constructed from materials such as stainless steel (e.g., 316L), PVC, PVDF, or PTFE, selected for chemical compatibility and hygiene in food applications.

Control features

Units commonly feature adjustable stroke length or frequency control to regulate flow, with some offering external control inputs for automation.

Footprint

Metering pumps are generally compact, designed for integration into existing lines or skid-mounted systems, with dimensions varying by capacity.

• What kind of liquids can this pump handle?

  Metering pumps are designed for precise dosing of a wide range of low to medium viscosity liquids, including corrosive, abrasive, or viscous fluids, depending on the pump head materials.

• Is this pump suitable for continuous operation?

• What maintenance is typically required for a metering pump?

• Can this pump be integrated into an automated system?

• What are the key considerations when selecting a used metering pump?

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.
