METERING PUMPS / DOSING PUMPS

Prominent

Diaphragm metering pumps moves a precise volume of media at a continuous rate. These pumps offer adjustable flow rates, which can either be changed by adjusting the stroke length or by the pulses. This allows for easy operation for staff.

Features of the metering pumps includes, but is not limited to:

  • variable stroke rates
  • manufactured from chemical inert materials
  • manual or external electronic control - analogue and SCADA options available

WORKING PRINCIPLE

Metering / dosing pumps draw a measured amount of liquid into its chamber and injects the media into a tank or pipe that contains the fluid being dosed.

There are multiple components within a metering / dosing pump that ensure consistent dosing:

  • Pump: varying materials and size as per requirements for application
  • Injector: This is a one-way valve where the chemical is injected into the product - it overcomes pressure in the pipe and encourages the liquid to flow
  • Foot valve: This is a one-way valve that prevents the product from returning. It is placed into the product drum and keeps the pump primed.
  • Dosing line: a rigid tube or reinforced hose - either PE, PVC or stainless steel or high-pressure use.
  • Control system: this ensures accuracy of the metering / dosing pump and allows the operator to turn on and off at specific times.

APPLICATIONS

  • Chemical and pH dosing
  • Chlorine dosing and measurement
  • Batch dosing
  • Petrochemical and chemical processing
  • Water treatment and balancing
  • Mineral processing

PRODUCT INFORMATION

Global Pumps offer a wide range of ProMinent pumps for a variety of dosing applications.

Solenoid-Driven Metering Pumps

These Solenoid-Driven Metering Pumps are low-wear for low capacities. A magnet moves the solenoid shaft forwards and backwards by switching on and off. Two non-return valves prevent the dosing medium blowing back during pumping.

Features of the solenoid-driven metering pumps include:

  • capacity range: 1 to 75 l/hr at 2 to 25 bar back pressure
  • virtually wear-free power end/drive
  • long-term stability
  • cost-effective technical alternative in the lower capacity range
  • low energy consumption
Motor-Driven Metering Pumps

The Motor-Driven Metering Pumps provide high dosing precision and robust technology. The rotation of an electric motor is stepped down by a worm gear and converted via a cam into a linear stroke movement. The slide rod transmits this stroke movement to the diaphragm in the dosing head.

Features of the motor-drive metering pump includes:

  • extremely broad capacity range
  • high dosing precision even under varying pressure conditions
  • robust and cost-effective power end/drive in higher capacity classes
  • simple integration and retrofitting into automated processes
