Suction Shoe Gear Pump is suitable for continuous metering.

Press Release Summary:

Pump design maintains volumetric efficiency at elevated differential pressures and offers self-compensation for wear and thermal expansion, resulting in near zero slip. Its technology utilizes pressure-loaded suction shoe around internal gears. Discharge pressure keeps suction shoe seated tightly on top of gears, which prevents flow from decreasing at higher outlet pressures. Suction shoe technology is available in Series 180, 200, and 220 pumps.

Suction Shoe Gear Pump Boosts Volumetric Efficiency for More Accurate Metering

Micropump® offers a suction shoe gear pump design that maintains high volumetric efficiency even at elevated differential pressures. These pumps self-compensate for wear, resulting in near zero slip for more accurate continuous metering requirements. Ideal for numerous applications, the design increases overall pump performance and enhances durability.

Micropump's patented technology utilizes a pressure-loaded suction shoe around the internal gears. The discharge pressure keeps the suction shoe seated tightly on top of the gears, which prevents flow from decreasing at higher outlet pressures. This action allows the pumps to self-compensate for wear and thermal expansion, in turn providing better performance. The design uses a reduced number of parts to minimize downtime and extend pump life.

Micropump currently utilizes the suction shoe technology in its Series 180, Series 200 and Series 220 pumps. Additionally, helical gears are available in these pumps to assure accurate flow over a wide temperature range.

For more than 40 years, Micropump has led the fluid-handling industry in the development of miniature pumps and systems for OEM and industrial applications. Micropump operates as a business unit of IDEX Corp., a world leader in positive displacement pump technologies and other industrial products. As an IDEX company, Micropump utilizes Kaizen, Lean Manufacturing and Six Sigma process improvement strategies to improve quality and increase value in its product.
