Product category: Pumps

Micropumps for dosing and conveying

The pumps dispense small and very small quantities of liquids quickly and precisely. These micro annular gear pumps (mzr® pumps) make conventional metering applications more effective and thus open up new fields of technology.

The pumps are characterized by their low weight and compact design as well as low pulsation, long service life, low empty volume and low-shear delivery. Five series of mzr® pumps enable smallest dosing volumes from 0.25 µl and volume flows from 1 µl/h to 1152 ml/min as well as pressures up to max. 150 bar.

In addition to numerous applications in mechanical and plant engineering, in the chemical and pharmaceutical industries, mzr® pumps perform demanding metering tasks in laboratory and analytical technology, diagnostics, biotechnology, chromatography and other fields of application.

Micro pumps for smallest dosing volumes

Precise pumps - smart solutions. The pumps dose small and very small quantities of liquid fast and precisely. These micro annular gear pumps (mzr® pumps) make conventional dosing applications more effective and thus open up new fields of technology.

The pumps are characterized by their low weight and compact design, low pulsation, long service life, low dead volume and low shear delivery. Five series of mzr® pumps enable the smallest dosing volumes from 0.25 µl and volume flows from 1 µl/h to 1152 ml/min as well as pressures up to 150 bar.

In addition to numerous possible applications in mechanical and plant engineering, in the chemical and pharmaceutical industries, mzr® pumps perform demanding dosing tasks in laboratory and analytical technology, diagnostics, biotechnology, chromatography and further fields of application.
The pumps and dosing systems offered by HNP Mikrosysteme GmbH are made in Germany. The products are based on 20 years of experience in product development, application consulting and customer-specific adaptations and integrations.

Dosing of highly viscous material for microencapsulation

Microencapsulation is becoming increasingly important in pharmaceutical, cosmetics, food and agricultural industries. New dosage forms are emerging, the efficacy and tolerability of active substances is increasing, and the range of applications for approved substances is growing. Precise metering techniques in the low-volume range are a necessary prerequisite for the production and processing of APIs. Metering pumps by HNP Mikrosysteme are a suitable technical solution.

Active pharmaceutical ingredients (APIs) are the pharmacologically active substances of a drug. These are compounds such as natural substances, semi-synthetic products, synthetically produced or genetically and biotechnologically modified pharmaceuticals and cosmetics. The production of these APIs is demanding. The substances, which range from aqueous to oily, need to be processed gently.
 
Microencapsulation is a suitable process to protect these active substances from early release and to preserve bioactivity. The capsules consist of polymeric or inorganic materials. Depending on permeability and degradability, the active substances are gradually released. Continuous release makes drug therapies much better tolerated with fewer side effects.

The capsule material usually has a viscosity of over 10,000 mPas. The volume flow rate is in the range of a few microliters per minute up to 140 ml/min. The precision of the delivery is essential for the quality of the capsules with tolerances ±1 %. Micro annular gear pumps by HNP Mikrosysteme are well suited for this demanding task. Due to the high viscosity, high-performance pumps such as mzr-6305 and mzr-11508 are used. Both pumps can be heated or additionally equipped with a gearbox, for small quantities. Depending on the production process, dosing of the coating material can also be considered instead of continuous delivery.

Capsule band sealing is another method of production. To seal the two capsule halves, a liquid quantity in the microliter range is sprayed on in advance. The APIs can also be dosed with pumps from the high-performance series or alternatively, with hermetic inert pumps from HNPM. The content of a capsule is usually between 0.2 and 1 ml. In cosmetics and food production, the quantities are particularly small. Spheres or pearls are used here. Hermetic inert pumps such as mzr-7255 are also used in production processes for active pharmaceutical ingredients.
