mzr-2909X2 Ex

Product catalog summary

Description: The mzr-2909X2 Ex micro annular gear pump is designed for precise, low pulsation dosing of small volumes, suitable for non-lubricating liquids and high-pressure applications. It features a compact design, broad viscosity range, and small dimensions, making it ideal for chemical and process technology applications. The pump supports continuous delivery and discrete dosage of various liquids, including watery solutions, solvents, and oils.

Advantages: The pump is ATEX certified, conforming to EU Directive 2014/34/EU, and features a precision motor with an integrated microcontroller. It offers high dosage precision with a coefficient of variation (CV) of less than 1% at low volumes. The compact design includes a length of less than 356 mm with the Ex-motor, and it supports a broad viscosity range from methanol to gels. The rotary micro annular gear technology ensures low pulsation delivery and low shear stress.

Technical Data: The pump has a flow rate of 0.003 - 12 ml/min, with the smallest dosage volume of 0.5 µl and a displacement volume of 3 µl. It operates within a differential pressure range of 0 – 5 bar and can handle a maximum inlet pressure of 5 bar, extendable to 10 bar with an optional fluidic seal module. The ambient temperature range is 0 to +40 °C, and the liquid temperature range is -5 to +40 °C. It supports a viscosity range of 0.3 - 5,000 mPas and is certified for Ex-area zones 1 and 2.

Materials and Motor: Wetted parts include stainless steel 316L, Ni-based tungsten carbide, and graphite-reinforced PTFE seals. The motor is a BLDC type with an integrated motion controller, operating at 24 V DC and 53 W, with a velocity range of 1 - 4,000 rpm.

Remarks: Performance may vary based on parameter combinations, and specifications are subject to change without notice. Customized solutions are available upon request.

Accessories: Available accessories include a terminal box S-G05, mzr-Touch Control, and a plastic reservoir.

Patents and Trademarks: The product is protected by several national and international patents, and trademarks such as HNPM®, mzr®, and others are registered to HNP Mikrosysteme GmbH.
