Gear pumps are commonly used for applications where fluids with high viscosities, high pressures and high temperatures have to be handled. Now, this firm has redesigned a gear pump, which has been used for years for conveying highly viscous, molten plastics, to handle all other chemical fluids with similar properties, such as resins or silicones, polyurethanes and polymer solutions, and highly viscous food additives. The pump features a slim construction and a large inlet, which makes it possible to reduce the net positive suction head required to be as low as 100 mm Hg. The design is capable of reliably conveying viscous fluids from vacuum containers. — Maag Pump Systems AG, Oberglatt, Switzerland
