mzr-11557

Product catalog summary

Description: The mzr-11557 is a micro annular gear pump from the hermetic and chemically inert series, designed for aggressive and corrosive media. It features ceramic rotors and functional elements, providing high chemical resistance and wear resistance. The pump includes a magnetic coupling and case components made from alloy C22, making it suitable for chemical industry applications.

Advantages: The pump offers high resistance to corrosion from oxidizing and reducing media, acids, and bases. It is hermetically sealed with a magnetic coupling and has a long service life due to wear-resistant ceramic components. Optional thermal heating is available with double shell technology. The pump head is chemically inert, made from alloy C22, SSiC, Al2O3, and ZrO2-ceramics. It features a high-power AC motor for use with an external frequency inverter and low pulsation rotary micro annular gear technology without valves.

Applications: The mzr-11557 is suitable for flow chemistry, microreaction technology, and mini plant technology.

Technical Data: The pump has a flow rate of 29 - 1152 ml/min and a displacement volume of 192 µl. It can handle a maximum system pressure of 60 bar (870 psi) and a differential pressure range of 0 – 60 bar. The liquid temperature range is -5 to +60 °C, with an optional range of -20 to +100 °C. It supports a viscosity range of 0.3 - 1000 mPas and a precision CV of less than 1%. The velocity range is 300 - 6000 rpm, and it has a 3/8" NPT internal thread fluid connection. Wetted parts include a pump case made of alloy C22, with optional stainless steel 316L, and seals made of FFKM, with optional FPM and EPDM. The shaft/bearing is made of sintered silicon carbide, and the rotors are TAZ composite ceramics, with an optional tungsten carbide Ni-based material.

Motor: The pump uses an AC motor, IEC-Size 056, with 4 poles, IP 55, rated voltage of 240/400 V, and rated frequency of 100 Hz, with a power of 240 W. It includes temperature protection with a thermal contact (NC).

Dimensions and Weight: The pump measures 291 x 130 x 171 mm and weighs approximately 11 kg.

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

Patents and Trademarks: The pump and its housings are protected by several patents, including EP 1 354 135 B1 and US 7,698,818 B2. HNPM®, mzr®, and other related names are registered trademarks of HNP Mikrosysteme GmbH.
