Focused on Flow Stability and Accuracy

This precision micro gear pump is engineered for applications where flow consistency is more important than high pressure. It is a positive displacement pump with a fixed displacement per revolution. This design ensures that the output flow is directly proportional to the shaft speed. The standard construction uses 316L stainless steel. We also offer 2205 duplex steel, TC4 titanium alloy, or C276 Hastelloy for corrosive or high-purity media. The displacement is 0.2 to 26 ml/rev. This translates to a flow of 0.6 to 65 L/min. The speed range is 100 to 4000 rpm. This gives you fine control over the output rate.

Operating Envelope for Sensitive Applications

The precision micro gear pump operates within a temperature range of -120°C to +150°C. This wide range allows it to handle cryogenic fluids as well as heated process liquids. The suction lift is -0.85 Bar. This enables the pump to self-prime under many conditions. The differential pressure for water is 20 to 30 Bar. The maximum system pressure is 25 to 40 Bar. These specifications are suitable for laboratory equipment, fine chemical dosing, precision coating machines, and micro-fluid circulation systems. The pump's output remains stable even when inlet conditions vary slightly.
Precision Machining for Tight Internal Clearances

The pump's accuracy comes from the tight internal clearances between its gears and the pump body. These clearances are achieved through precision CNC machining. The gear profiles are cut with high precision to ensure smooth meshing and consistent volumetric displacement. The pump body is machined from solid material. This eliminates the porosity that can be present in castings. The bearing arrangement supports the gear shafts precisely. This maintains the gear alignment under load. These engineering choices ensure that the pump delivers the same flow rate at the same speed, day after day.

Customization for Your Specific Needs

We offer customization for this precision micro gear pump. You can select the pump body material based on your fluid chemistry. You can specify the port threads and sizes to match your system connections. You can also request changes to the mounting configuration. We work from your technical requirements. Our engineering team will check that the custom pump still meets its flow accuracy targets. This gives you a pump that is tailored to your application, not a standard product that you have to adapt to.
