Metering pumps

Overview

Medray procures metering pumps for maintenance, replacement and project requirements. Provide the model or reference, quantity and operating conditions so the required configuration can be matched and sourced across available suppliers. Metering pumps deliver a controlled quantity of chemical into a process stream. Solenoid-driven diaphragm designs use repeated dosing strokes, with output adjusted through the available stroke and control settings. Pump-head materials, diaphragm compatibility, venting and injection arrangements should match the chemical. Required output must be checked at the actual back pressure rather than inferred from a maximum family rating. Technical details to confirm: Chemical identity and concentration; Required dosing rate at operating back pressure; Manual, proportional or instrument-linked control; Pump-head material, venting and injection accessories.
