A propeller pump is a high-flow, low-lift, impeller-type device with a linear flow path. The propeller pump can be installed in a vertical, horizontal or angled orientation and typically has its motor positioned above the water level with the impeller below the water.
Propeller pumps work by drawing water through an outer casing and out of a discharge outlet through a propeller vaned head. Propeller pumps are used in water treatment facilities, chemical plants or agricultural applications where high head values are not required. Compared to other standard pump designs, they have several advantages, such as high flow capacities, the ability to pump suspended sand, and priming-free operation.
Parts that make up a water pump
Currently, iron pumps have given way to cast aluminum ones, which are usually made up of the following main elements:
Propeller
Pulley
bearing shaft
armed shaft
Closing
The propeller is connected to the pulley through the bearing shaft, which is usually driven by the timing belt by another service belt or ancillary accessories. Two vital elements in the operation of the pump are the reinforced shaft and the seal since they are the ones that ensure the tightness of the assembly, and if they fail, they will cause overheating in the motor. Propeller Pumps Manufacturer India made all elements related to pumps.
How it works?
Propeller pumps are of a conventional rotary impeller design and are used in applications with high volume flow and moderate head requirements. In these cases, the head refers to the total height of the pump capable of moving the 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.
The impeller head is equipped with propeller-style blades and can be single or multi-stage. The suction head section of the casing that houses the impellers is usually equipped with a strainer attachment that prevents the ingestion of large foreign objects.
When the pump runs, the rotating impeller draws water out of the casing and through an angled discharge pipe. The fact that the water moves in a straight line up the pump casing instead of in a circular direction represents the clearest difference between the propeller and other impeller pumps.

Horizontal propeller pump installations generally have hermetic submerged motors mounted directly behind the impeller head. These models usually are used when the pump draws water through a tank wall or bulkhead. Free-floating propeller pumps are mobile units mounted on a specially designed pontoon that can be moved around the body of water if the need arises. Angled pumps are often installed in tanks with steeply sloping walls.
Propeller pumps do not present high head values; the average is between 20 and 40 feet (6 to 12 meters). The propeller pump also has several distinct advantages over other pumps, including high flow volumes, the ability to pump suspended silt, and a wide range of possible drive options. The fact that the impeller head is always submerged also means that the pumps never have to be primed before use.
