Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.[1] 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. Centrifugal pumps are often chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering.The reverse function of the centrifugal pump is a water turbine converting potential energy of water pressure into mechanical rotational energy.
A submersible pump, also called an electric submersible pump, is a pump that can be fully submerged in water. The motor is hermetically sealed and close-coupled to the body of the pump.
A gear pump is a rotary pump with a positive displacement that transports fluids using a rotating gear. They work through the use of two or more internal gears that create vacuum, propel the liquid. Gear pumps are compact, high pressure pumps that deliver constant fluid flow compared to double diaphragm pumps and osmosis pumps. They are best suited for high viscosity applications such as oils, plastics, paints, adhesives, or soaps.
Metering pumps are chemical pumps with low volume flow, which can control flow automatically or manually depending on the job requirements to be applied. In particular, the pump accuracy is very high and can pump many different chemicals such as acids, bases, high corrosive substances or viscosity substances, ... The material that makes up the metering pump is usually made of PVC. , PP .... pump membranes are teflon membranes, these are materials that can withstand most chemicals.
The pneumatic diaphragm pump is also known as the chemical diaphragm pump, which is a specialized pump for pumping chemicals and food, with the principle of operation is a combination of the diaphragm made of rubber material, the plastic moves back and forth inside the pump head and the balls act as the lock valves. In it, thanks to the effect of compressed air, or an electric motor, the diaphragm can be moved back and forth. In other words, a pneumatic diaphragm pump is a combination of diaphragm pump and pneumatic pump.
Centrifugal pumps are centrifugal pumps that don't have a sealess. The external magnet unit attached to the pump shaft transmits the driving force to the inner magnet attached to the impeller and from there the impeller rotates to push the liquid. The outer and inner magnets are separated.
Screw pump, for engineers or technicians often call another name is chicken gut pump. The screw pump is called a chicken gut pump because the part that helps to circulate water is a spiral shaft that looks similar to a longitudinally cut chicken gut. The main components that make up the screw pump are seal, shaft, rotor, and stator.
A lobe pump, or rotary lobe pump, is a type of positive displacement pump. It is similar to a gear pump except the lobes are designed to almost meet, rather than touch and turn each other.
