Product Details Supplier Info More products

Michael Smith Engineers has introduced the MZR range of micro annular gear pumps from HNP Mikrosysteme. This pump range is suitable for applications requiring the accurate, fast and pulse-free dispensing and metering of small volumes of liquids.

The MZR range comprises six series of pumps: the high-performance series, the hermetic insert series, the low-pressure series, the modular series, the magnetic hermetic series and Ex-versions of the high-performance and hermetic inert series.

The pumps cover many duty parameters, including dispensing volumes from 0.25µL, flow rates from 1µL/hr to 1.1 litre per minute and discharge pressures between 0 and 150 bar for liquids with viscosities between 0.3cP and 1,000,000cP.

All MZR pumps give low pulsating flows and can be used on non-lubricating liquids.

MZR range in detail

High-performance series

  • Suitable for more challenging dosing tasks requiring high precision
  • Covers medium to high pressures and a wide viscosity range
  • Features a double-sided bearing system and is driven by a DC servomotor with integrated control

Hermetic inert series

  • Suitable for more aggressive liquids thanks to the material options available for internal wetted components
  • Offers excellent chemical and wear resistance

Low-pressure series

  • Designed for the precise dosing of low-viscosity liquids at low pressures
  • Suitable for less demanding applications, such as transferring low volumes of non-lubricating liquids

Modular series

  • Suitable for handling corrosive liquids
  • Wetted components available in a choice of different inert materials

Magnetic hermetic series

  • Suitable for handling crystallising and air- or moisture-sensitive liquids as the pump has no shaft seal
  • Can be replaced by a liquid separating cup and a magnetic drive
  • Ensures leak-free operation with long service life and low energy consumption

Ex-version of high-performance and hermetic inert series

  • Suitable for hazardous-area applications
  • Equipped with Ex-approval drives
  • Features Atex approval according to EU Directive 94/9/EC
