Centrifuge pump power and capacity calculations involve understanding the pump's efficiency, flow rate, and head.

• Calculate the pump's power using the formula: Power (kW) = (Q x H x SG) / (3.6 x η)

• Determine the pump's capacity by calculating the flow rate (Q) in m^3/s

• Consider the pump's head (H) in meters and specific gravity (SG) of the fluid being pumped

• Efficiency (η) of the pump is crucial for accurate power calculat...read more

A liquid ring compressor is a type of rotary positive displacement pump that uses a liquid seal to create compression.

• Uses a rotating impeller with blades to compress gas by creating a liquid ring around the impeller

• The liquid ring acts as a seal and helps in compression of gas

• Commonly used in applications where a continuous flow of gas with low pressure is required, such as in vacuum systems or wastewater treatment pl
