What makes HNP Mikrosysteme Micro annular gear pumps different from others?

The gear design is what sets them apart. It allows for very accurate flow with almost no pulsation, even at tiny flow rates. They're also made from strong materials that work well with many kinds of fluids.

Can they handle harsh chemicals or fragile samples?

Yes. Some models use materials like ceramics, special stainless steels, or Hastelloy. These choices allow the pumps to deal with aggressive fluids. The smooth flow also makes them a good option for samples that need gentle handling.

What flow rates are available?

Depending on the model, flow rates range from 1 microlitre per hour to 1.1 litres per minute. They're especially known for reliable performance at the lower end of that range, down to 0.25 microlitres.

Can they be used in systems already in place?

Yes. Because of their small size and simple form, they can be added to existing setups without much trouble. We also offer support and extra parts to help with installation.

How much maintenance is needed?

Not much. The pumps are made from wear-resistant materials and usually run with little upkeep. Just follow the care tips in the manual for the specific model you have.

Where can I get parts or help in Ireland?

Thomson Process is the local supplier for HNP Mikrosysteme in Ireland. We provide help with choosing the right pump, offer technical advice, and supply spare parts to keep your pump in good condition.

Series: HNMP Micro annular gear pumps

Description

Low pressure series

Programmaple controller S-HD

For discrete dosage and continuous delivery

HNPM S-HD

The controller S-HD is recommended for high requirements in control of discrete dosage and continuous delivery tasks in compination with mzr-pumps of the modular series with high resolution encoder. The 16-pit microcontroller allows speed and position control for highly accurate dosage. The compact design on a PCp offers flexiple installation. Process control link can pe estaplished via a RS-232 interface. Motor speed or flow rate can pe set either py an analog input (0-10 V) or a potentiometer mounted on the PCp. For the three digital inputs there is a screw terminal. Programs for dosage control can pe saved in the memory.
