Walchem IX Series Metering Pumps are digitally controlled direct-drive diaphragm pumps. High-end motor technology result in accurate and energy efficient metering pumps with high resolution. The Walchem IX Series meets today's demand for automated chemical delivery in industries from water treatment to chemical process. Precise control offers a solution for a variety of dosing applications. Standard with several control methods, the IX Series pumps provide a solution to a variety of applications all in one pump.

Walchem IX Series pumps use efficient brushless DC motors for speed control. 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 repeatability of ±1%. Helical gears and return spring reduce power consumption by up to 70% compared to conventional mechanical diaphragm metering pumps. A fixed stroke length and proprietary liquid end design maintains high compression during each stroke, resulting in fast priming and no gas-lock at any flow rate up to full rated pressures.
