Mechanical Piston-Plunger
Metering Pumps
Mechanical Piston Metering Pump
Piston metering pumps for continuous operation flow rates to 304 litres per hour range with fixed
ratio gearbox that greatly reduces mechanical stress with multiple combinations motor size, piston lengths and chemical
resistant dosing heads available for aggressive chemicals, pumps hydraulic characteristics adaptable for a multiple processes where low
flow rate metering pumps are best suited to produce accuracy and performance regardless of working conditions.
Piston- Metering Pumps
Reliability & Performance
Motor-driven piston dosing pumps are a positive
displacement pumps with a fixed ratio gearbox & motor to drive the piston/plunger in a reciprocating action inside
the dosing head to draw and discharge chemical into the process being with the output relatively unaffected by
fluctuating backpressure changes, highly efficient with viscous liquids or heavy chemicals with linear flow throughout
the dosage scale even when used in high pressure processes
Mechanical Plunger Dosing Pump
Mechanical plunger dosing pump range designed for flow rates up to
1000 litres per hour and operate over long periods with fixed speed gearbox, high torque motors and piston spring
return mechanism to maintain precision and minimise mechanical stress, flow rates are adjusted manually
or automatically through a motorised actuator operating off a current 4-20mA input signal often generated from process
control instruments such as pH-Chlorine-Redox digital controllers.
Motor-Driven Plunger Dosing Pump
Mechanical plunger dosing pump with reinforced body for high pressure 100 bar processes,
combines high-torque electric motor, fixed ratio gearbox and spring return piston mechanism to help minimise mechanical
stress in high pressure processes, manually adjustable stroke length or for complex processes or via electric actuator externally operated by
a PLC system or process controller allowing remote flow rate adjustments without pausing the production line.

Precise Chemical Metering
A mechanical piston or plunger dosing pump flow rate is directly proportional to the stroke length
and motor speed due to their design the reciprocating action of the piston this linear relationship across the pumps dosage scale
retaining a flow tolerance & accuracy unaffected by chemical viscosity or pressure fluctuations.
Flow Rates 9 ÷ 2300 l/Hr - Pressure 100 Bar
Low Dependence on Back-Pressure
Mechanical piston/plunger dosing pumps are fundamentally different to other types pumps the most
significant advantage is that the pumps flow rate output is independent on backpressure delivering a volumetric
efficiency of between 90% to 98% displaced per stroke whether the backpressure is 2 bar or 100 bar.
