Gear Pump Manufacturers - Gear Pump Design: Good Suction Characteristics

In which areas of gear pump design is applied, what is the application significance, the Gear Pump Manufacturers
answers:

The gear pump is designed for cleaning liquids. Make sure they draw liquid from the top of the supply tank in the clean liquid space. It can pump low viscosity and high viscosity liquids. If pumping sensitive food grade products (ie pump agitation to destroy cells and fibers) is to be pumped, it is necessary to increase the size and speed of the pump.

The design also has good suction characteristics and can be used to draw clean, low viscosity liquids from good depth or distance. In the case of pumping high viscosity liquids, or when stretching from depth or distance, liquid can easily flow into the pump. Install large diameter suction lines, keep them shorted and try to keep the pump below the supply tank so that the suction is under the positive pressure head of the stored liquid.

Very fine tolerances prevent pumping of any solids or particulates as it can squeeze between the teeth and damage the pump. If there is a risk of drawing solids into the pump, a suction tube filter that is easy to clean must be installed. Use a fine mesh screen whenever possible without significantly increasing the suction pressure loss, otherwise the pump will cavitation. If the particles are too fine to pass through the screen, it is best to choose a different pump design.

As a positive displacement pump, each rotation provides a very precise amount, which means that they have good dose characteristics regardless of speed. The gear pump produces a good chemical additive metering pump that
solves material compatibility problems.
