A propeller pump is a high-flow, low-lift impeller-type device with a linear flow path. Propeller pumps are generally mounted with the impeller below water level and the motor above. However, they can also be installed vertically, horizontally, or at an angle. These pumps draw water through an outer casing and out of a discharge outlet through a propeller-bladed drive head. Propeller pumps are used in water treatment facilities, chemical plants, or agricultural applications where high head values are not required. According to Propeller Pumps Manufacturer India, compared to other standard pump designs, they have several advantages, such as large flow capacities, the ability to pump suspended sand, and prime-free operation.
Propeller pumps have a conventional rotating impeller design and are used in applications with large flow volumes and moderate head requirements. In these cases, the head refers to the total head where the pump can move water. Depending on the specific application, these can be oriented vertically, horizontally or at an angle. Vertical and angled propeller pumps typically have a drive motor above the water on top of a tubular casing. The pump drive shaft is routed to the impeller head at the bottom of the casing through support bearings in a sealed inner tube.
As per Pumps manufacturer India, the impeller head is equipped with propeller-style blades and may consist of single or multi-stage. The suction head section of the housing that houses the impellers is usually fitted with a filter fitting that prevents ingestion of large foreign objects. When the pump runs, the rotating impeller draws water through the casing and an angled discharge pipe.
