IX Pumps

A new class of advanced metering pumps! Walchem's IX Series are digitally controlled direct-drive diaphragm pumps.  Years of experience in high-end motor technology result in extremely accurate and energy efficient metering pumps with high resolution.  The IX Series meet today’s demand for automated chemical delivery in industries from water treatment to chemical process.  Highly precise control offers a solution for a variety of dosing applications.


  • Standard Features:

    High Turndown Ratio Motor control adjusts the discharge and suction speeds to meet a full and accurate turndown ratio of 750:1 (300 l/h to 200 ml/h).


    High Accuracy Combined with precise motor control, an efficient valve design maintains accurate flow rates to allow a low-cost, mechanically-driven diaphragm pump to achieve a high accuracy of ±1%.


    Energy Savings Helical gears and return spring reduce power consumption by up to 70% compared to conventional mechanical diaphragm metering pumps.


    High Compression Pump Head Design A fixed stroke length maintains high compression in each stroke resulting in fast priming and no air-lock at any flow rate up to rated pressures.
