High viscosity fluid applications present unique challenges when it comes to getting fluids into the pump and out again without blockage or hindrance to flow rates. Blockages result in system downtime and affect production, which in term reduce output and profit.
Gear pumps, internal and external, are commonly used in high viscosity fluid applications. However, the gears can be easily damaged when pumping large solids. Gear pumps also require frequent maintenance, which halt production and increase overhead.
