Pump and volute casing. A volute is a curved funnel that increases in area as it approaches the discharge port. [1] The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the ...
The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits. Common uses include water, sewage, agriculture, petroleum, and petrochemical pumping.
Several different types of pump impellers Flexible impeller of cooling system pump of an outboard engine (1 euro cent coin for comparison, diameter 16.25 mm). An impeller is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped.
The fluid then passes through a volute or a diffuser, which is a ring with multiple diverging channels. This causes an increase in dynamic pressure as fluid velocity is lost. The volute or diffuser turns the high kinetic energy into high pressures (hundreds of bars is not uncommon), and if the outlet backpressure is not too high, high flow ...
While centrifugal pumps impart momentum to the fluid by motion of blades, positive displacement pumps transfer fluid by variation in the size of the pump’s chamber. Centrifugal pumps can be of rotor or propeller types, whereas positive displacement pumps may be gear-based, piston-based, diaphragm-based, etc.
Ford Motor is recalling 295,449 diesel-engine trucks because a defective fuel pump could cause a loss of power, raising the risk of a crash, the National Highway Traffic Safety Administration said ...
The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits. The gear pump is a marine gear pump that uses the meshing of gears to pump fluid by displacement. It is one of the most common types of pumps for ...
