Screw Pump

What is screw pump?

A screw pump is a pump that uses one or more screws to move fluids or solids along with the screw axis. In simple words, a single screw rotates in a cylindrical cavity, thereby moving the fluid or solid material along the screw’s spindle. The spindle is responsible for the pumping action of the pump.


Screw pumps are generally made from traditional low-carbon steel (mild steel) with a special epoxy coating. An appropriate coating system is selected for each specific application.

Types of screw pumps

Screw pumps are of three types:
  • Single screw pump
  • Two screw pump
  • Three screw pump

Single screw pump

A single screw pump contains a single pumping element called screw. This screw rotates within a stationary elastomeric stator.

The interference fit between the screw and the flexible stator create a unique pump design that can handle a variety of fluids, including high levels of solids and variable viscosities. A single screw pump is also known as progressive cavity pump or eccentric screw.

Two screw pump

The two screw pumps are operated using two intermeshing screws rotating within a stationary bore that is shaped like a figure eight. These pumps are also known as double screw pumps or twin screw pumps. The two screw pumps are used mainly to pump fresh water, mineral water and sea water with petroleum products admixture. These pumps are also used to pump viscous liquids and fuel oil. The rotor and housing are metal and the pumping element is supported by the bearings in this design.

Three screw pump

Like the two screw pump, the three screw pump also operates on the same principle of intermeshing screws. The three screw pump utilizes a centrally located primary screw, which intermeshes with two secondary screws to create pressure and move fluid.

The idler rotors are located 180 degrees from each other, are suspended within the pump and do not penetrate the housing. The power rotor pass into the housing and requires one seal and one bearing; there may be bushings/sleeve bearings that are exposed to the pumped fluid.

Screw pump applications

  • Fuel transfer
  • Elevators
  • Storm water pumping
  • Drainage pumping
  • To move industrial waste water

Advantages of screw pumps

  • High reliability
  • Simple and rugged design
  • The open structure and slow rotation speed makes it a heavy duty pump.
  • A typical screw pump has a lifetime of between 20-40 years.
  • A screw pump can operate even when there is no water in the inlet. So it is not necessary to install expensive measures to prevent dry running.
  • A screw pump requires very less maintenance as compared to other pumps.
  • High efficiency

Boiler feed pumps manufacturers



Boiler feed pumps manufacturers

A boiler feed water pump is a specific type of pump used to pump feed water into a steam boiler. The water may be freshly supplied or the condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the centrifugal or positive displacement type of pump. Cooling water pumps vary in size up to many horsepower and the electric motor is often separated from the pump body by some form of mechanical coupling. Large industrial condensate pumps can also serve as a feed water pump. In any case, in order to force the water into the boiler, the pump must generate sufficient pressure to overcome the vapor pressure developed by the boiler. This is usually achieved by the use of a centrifugal pump.


Another common form of boiler feed water pumps operates constantly and is provided with a minimum flow device to stop pump overpressure at low flow rates. The minimum flow normally returns to the tank

Steam locomotives and steam engines used on ships and stationary applications, such as power plants, also require feed water pumps. In this situation, however, the pump was often fed with a small steam engine that operated with the steam produced by the boiler. Of course, a means had to be provided for putting the initial charge of water into the boiler (before steam power was available to run the steam-powered feed water pump). The pump was often a positive displacement pump that had valves and steam cylinders at one end and feed water cylinders at the other end; No crankshaft was required.

Submersible pump price in Bangalore


Submersible pump price in Bangalore

Mieco generators are the best manufacturers and distributors of submersible pumps in Bangalore, India. Submersible pumps are used by immersing them in fluid. Submersible pumps used in ESP installations are multi-stage centrifugal pumps that operate in an upright position. Although its constructive and operational characteristics experienced a continuous evolution over the years, its basic operating principle remained the same.

The liquids produced, after being subjected to large centrifugal forces caused by the high speed of rotation of the impeller, lose their kinetic energy in the diffuser where a kinetic energy conversion takes place under pressure. This is the main operating mechanism of radial and mixed flow pumps. Submersible pumps are found in many applications. Single-stage pumps are used for drainage, sewage pumping, general industrial pumping and sludge pumping. They are also popular with pond filters.

Multi-stage submersible pumps are usually lowered by a drilling well and are typically used for residential, commercial, municipal and industrial water extraction (extraction), water wells and oil wells.

Other uses for submersible pumps include sewage treatment plants, seawater management, fire fighting (as it is a fire-resistant cable), drilling of water wells and deep wells, offshore drilling rigs, artificial elevators, dehydration Of mines and irrigation systems.

Particular attention is required to the type of submersible pump when certain types of liquids are used. Pumps used for combustible liquids or water that may be contaminated with combustible liquids must be designed not to ignite liquid or vapors.
