Key Features of HNMP Micro Annular Gear Pumps

Highly Accurate Fluid Control

These pumps are built to deliver exact amounts of liquid, down to tiny microliters. That means consistent dosing without waste, perfect for critical tasks.

Smooth, Steady Flow

The low-pulsation flow is smooth and soft because of its clever internal architecture. This prevents harm to sensitive fluids such as chemicals, biological samples, or thin oils.

Works with Thin and Thick Liquids

These pumps are capable of handling substances as thick as honey or as thin as vodka. They are extremely versatile, supporting a wide range of viscosities.

Compact and Easy to Fit In

The pump units are small and compact, making them ideal for tight spaces or equipment where space is limited. Perfect for lab systems, automated lines, or mobile setups.

Tough and Built to Last

Made with strong materials like stainless steel and ceramics, they’re built to handle aggressive chemicals and high-performance environments.

Smart Control Options

These pumps often have integrated motors and electronic control interfaces, such as RS232 or analog inputs, making them easy to connect to automation systems or use manually.

Low Maintenance

They’re designed to run reliably with minimal wear and tear, meaning less downtime and fewer service needs.

Used Across Many Industries

From pharmaceuticals and chemicals to food additives, fuel cells, and lab testing, these pumps are trusted anywhere precise liquid handling is essential.

What industries commonly use Micro Annular Gear Pumps?

Pharmaceutical & Biotech

These pumps are great for measuring tiny, accurate amounts of liquids, which is essential when making medicines, vaccines, or running lab tests. They help deliver fluids consistently without waste, perfect for sensitive and sterile environments.

Chemical Manufacturing

In factories where chemicals are mixed or added to products, these pumps make sure just the right amount is used. They’re also built to handle corrosive and aggressive fluids that would damage regular pumps.

Laboratory Automation

Used in high-tech labs, these pumps automate the dosing of samples, solvents, and reagents, allowing for faster, more accurate testing and research.

Battery & Fuel Cell Production

When building batteries or fuel cells, precision is key. These pumps are used to apply electrolytes or chemical coatings in a way that’s smooth and controlled, crucial for performance and safety.

Food & Beverage (Additives & Flavors)

Micro annular gear pumps are also found in the food world, where they dose small amounts of flavors, colors, or nutrients into products. Clean, accurate, and food-safe options are available.

Cosmetics & Personal Care

In the production of creams, lotions, and other cosmetics, these pumps help precisely mix and fill products that often include expensive or delicate ingredients.

Automotive & Industrial Coatings

They’re used to apply adhesives, sealants, and coatings in the auto and manufacturing industries, especially where exact amounts matter for quality and safety.

Frequently Asked Questions

Are the pumps suitable for high-pressure applications?

Yes, many models in the mzr® series are designed to handle high-pressure situations, depending on your chosen version. For example, pumps like the mzr-7245 can operate at pressures up to 5 bar with optional support. That makes them ideal for applications where fluids must be moved through tight systems or over long distances without losing performance.

What flow rates can the mzr® series handle?

The mzr® pump series covers a wide range of flow rates, from just a few microlitres per hour up to around 1,150 millilitres per minute, depending on the model. This flexibility means you can use the same type of pump whether you’re dosing micro-quantities in a lab or delivering larger volumes in an industrial setting.

Can the pumps be used in continuous and batch processes?

Absolutely. These pumps are great for both continuous flow applications, where a steady stream of fluid is needed, and batch dosing, where exact, repeatable volumes are delivered in set amounts. They’re commonly used in automated systems where both types of operation might be required at different times.
