Walchem's IX Series Metering Pumps are a New Class of Digitally Controlled Direct-Drive Diaphragm Pumps

Walchem's IX Series Metering 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.

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.

Walchem's IX Series Metering Pumps Attributes

Maximum viscosity :IX-C: 1000 cps IX-D: 300 cps (standard pumps - consult factory for higher viscosities)
Maximum discharge capacity is rated with clean water at ambient temperature at maximum discharge pressure. Output may
increase as pressure decreases.
Liquid temperature range: 0 -50°C (TC, TE type), 0-80°C (S6 type). No viscosity change. Non freezing. No slurry.
Operating temperature range: 0-50°C (Indoor use only)
Operating humidity range: 0-90% RH (Non-condensing in the controller)
Maximum dry suction lift is 6.5 ft. (2m).
Accuracy is not guaranteed at flows below 0.5GPH (2 LPH) for IX-D300S6, 0.26GPH (1 LPH) for IX-C150S6 or
0.11GPH (0.4 LPH) for IX-C060S6.
Pumps should always be shielded from direct exposure to the elements
