How to improve the performance of Rotary lobe pumps in chemical process?
Mar 25, 2019
There are five unit operations for chemical treatment. This article will focus on the fluid motion process, which is the most common transfer, filtration, solid fluidization and transportation. For reference, the other four unit operations are heat transfer (evaporation and heat exchange), mass transfer (distillation, extraction, adsorption and drying), thermodynamics (refrigeration and gas liquef...

Why mechanical seal and how to choose?
Apr 06, 2019
Why mechanical seal and how to choose? For more than 100 years, a variety of sealing materials, such as fillers, have been used to reduce the amount of liquid leakage from the liquid pump housing along the main shaft. The oldest seal design is still widely used in current liquid pumps because of its low starting cost and familiarity with the factory staff. However, due to environmental issues, the...

How to choose Rotor types for Rotor Pump?
Apr 12, 2019
The Rotor Pump achieves the purpose of transporting fluid by means of periodic conversion of a plurality of fixed volume delivery units in the working chamber. The Rotor Pump passes through a pair of synchronously rotating rotors during operation. The rotor is driven by a pair of synchronizing gears in the pump body, and rotates in the opposite direction through the main shaft and the auxiliary sh...
