Tips: What are the Disadvantages of Screw Pump?
Higher cost. Screw pumps can be more expensive than other types of pumps due to their more complex design and the materials used in their construction.
High maintenance. Screw pumps have more moving parts than other types of pumps, which can make them more difficult and expensive to maintain. Additionally, the screw and casing must be carefully machined to ensure proper clearance, which can add to the cost of manufacturing and maintenance.
Susceptibility to clogging. Screw type pumps can be more susceptible to clogging than other types of pumps, particularly if the fluid being pumped contains debris or other materials that can block the screw or the casing.
