Precision Gear metering pump is a special sub-category of external gear pump, which can provide accurate, reliable, and non-pulsating fluid metering under various application and process fluid conditions.

Many precision gear metering pumps are designed for the simple transmission of viscous liquids, while others are manufactured with very precise tolerances to meet the higher pressures and very precise flow rates required for precision metering applications.

Unlike pumps used in conveying applications, these pumps have a tighter internal operating clearance that minimizes internal fluid slippage, allowing for accurate metering and transmission of fluids.

Because of their precision tolerances and small gear sizes, these pumps can flow at a low speed of 0.5 cm 3/min at pressures of 10,000 psi and temperatures ranging from -40 F to 950 F.

The internal clearance of the precision gear metering pump is very precise, down to 50 parts per million (ppm), ensuring consistent flow and high-pressure capability.

In the processing industry, nothing is more critical than ensuring the integrity of the process itself. The pump systems that support these processes must be uniquely designed and configured to match the unique processes. The precision gear metering pump has the advantages of accurate transmission, reliable operation, and almost no-pulsation fluid transmission performance in metering applications.

Chemicals, extruded plastics, fiber spinning, coatings, adhesives, sealants, or other additives that support specific process operations or finished product production rely on precision gear metering pump metering, mixing, and spraying.

In these cases, flow differences due to flow instability and/or pulsation may result in complete damage to the finished product or defective product, this leads to lower productivity, increased rework, and excessive product waste, which will lead to higher costs for manufacturers.

The above is what the precision gear metering pump is for. Please feel free to contact us if you need to do so.
