• Phase Change Heat Pumps
• Thermoelectric Heat Pumps that use the Peltier effect
• Geothermal Exchange Heat Pumps
• Vortex Tubes

Features and Uses of Heat Pumps:

• Heat pumps are extremely efficient in their use of energy.
  
   
• A heat pump contains a valve that lets it switch between "air conditioner" and "heater." When the valve is switched one way, the heat pump acts like an air conditioner, and when it is switched the other way, it acts like a heater.
  
   
• A heat pump is a year-round comfort conditioning system that uses refrigeration equipment to supply warm air in winter and cool air in summer.
  
   
• A heat pump is growing in popularity because high energy costs and possibility of future fuel shortages have led house owners to seek ways to reduce their heating and cooling costs. The new models of heat pumps available today are extremely reliable and cost efficient.
  
   
• It is cost efficient because it provides both heating and cooling capabilities in one system.
  
   
• A heat pump will supply about two times more heat than energy used. The greatest savings with a heat pump usually occurs during the heating season.
  
   
• Low-maintenance operation.
  
   
• Heat pumps are typically somewhat more efficient for heating than for cooling.
  
   
• Heat pumps are also nowadays used to heat swimming pools and to heat water for household use.

In some cases, a sump pump is used when a lower floor is below the municipal sewer lines, to pump greywater or blackwater waste from that floor to the sewer lines.

sump pumps are installed particularly where basement flooding is seen as a problem, but are also used to ameliorate dampness where the water table is normally above the foundation of a home. sump pumps send water away from a house to any place where it no longer presents a problem, such as a municipal storm drain or a dry well. Older properties may have their sump pumps connected to the sanitary sewer, but this is frowned upon now (and may be against the plumbing code) because it can overwhelm the municipal sewage treatment system. sump pumps are usually hardwired into a home's electrical system, and may have a battery backup. Some even use the home's pressurized water supply to power the pump, eliminating the need for electricity. Since a sump pit may overflow if not constantly pumped, a backup system is important for cases when the main power is out for prolonged periods of time.

There are generally two types of sump pumps: pedestal and submersible. The pedestal pump's motor is mounted above the pit, where it is more easily serviced but also more conspicuous. The submersible pump is entirely mounted inside the pit, and is specially sealed to prevent electrical short circuits

AC Powered : In AC powered pump, the pump operates on a form of AC or alternating current voltage. An alternating current (AC) is an electrical current whose magnitude and direction reverses direction in a circuit at regular intervals.

DC Powered : In DC powered pump, the pump operates on a form of DC or direct current voltage. DC pumps run somewhat more efficiently than AC pumps. Direct current (DC) means electricity flowing in a constant direction, and/or possessing a voltage with constant polarity.

Battery : In case of power failure, the pump can also operate with the help of battery. In science and technology, a battery is a device that stores chemical energy and makes it available in an electrical form.

Air Pneumatic : Here, the pump is powered by a compressed air source.

Gasoline Engine : Pump is powered by a gasoline engine. Gasoline is volatile mixture of flammable liquid hydrocarbons derived chiefly from crude petroleum and used principally as a fuel for internal-combustion engines.

Diesel Engine : Pump is powered by diesel engine. It is an internal-combustion engine that burns heavy oil. Diesel is produced from petroleum. But, alternatives such as bio diesel or biomass to liquid (BTL) or gas to liquid (GTL) diesel that are not derived from petroleum are being developed and adopted.

Hydraulic : Pump is powered by a hydraulic system. It is worked by the force of a moving liquid.

Manual : Pump is manually operated by hand or foot power.

Natural Gas : Pump is powered by natural gas. Natural gas is a mixture of hydrocarbon gases that occurs with petroleum deposits like methane together with varying quantities of ethane, propane, butane, and other gases. It is used as a fuel.

Solar Powered : Here, energy derived from the sun or sunlight is used to run the pump.

Steam : Pump is powered by steam.

Water : Pump is activated by a flowing or pressurized water source.

• Aluminum
• Brass
• Bronze
• Cast Iron
• Plastic
• Stainless Steel

Aluminum
Aluminum is a silvery and ductile member of the poor metal group of chemical elements. Aluminum is found primarily as the ore bauxite. It is a light trivalent metallic element and has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. Aluminum is used in many industries to make millions of different products and is very important to the world economy.

Brass
The term used for alloys of copper and zinc in a solid solution is called brass. It is more than 50% copper and from 5 to 20% zinc. Brass comes with good strength. It has excellent high temperature ductility and reasonable cold ductility. Brass has also good conductivity and excellent corrosion resistance. Since it also has good bearing properties and low magnetic permeability, it is a ideal material for construction of pumps.

Bronze
The term used for alloys of copper and tin is called Bronze. Sometimes, bronze is also found with other elements such as phosphorus, manganese, aluminum, or silicon. It is strong and tough, and has wide range of uses in industry. Some types of brasses are also called bronzes. Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. It is not suitable for heavily loaded applications but is of great use where lubrication is inconvenient.

Cast Iron
There are various types of cast irons which are widely used in industry, especially for valves, pumps, pipes, filters and certain mechanical parts. Cast iron can be considered as an alloy of iron, silicon and carbon. Cast irons are natural composite materials whose properties are determined by their micro structures, that is, the stable and metastable phases formed during solidification or subsequent heat treatment. Cast irons have improved (corrosion) resistance and substantially modified mechanical and physical properties. Various types of cast irons used in the construction of pumps are:

• Gray Cast Iron
• White Cast Iron
• Chilled Iron (duplex)
• Malleable Cast Irons
• Ductile Or Nodular Cast Irons

Plastic
Plastic includes a range of synthetic or semi-synthetic polymerization products. It is composed of organic condensation or addition polymers and other substances to improve performance or economics. It is capable of being molded, extruded, cast into various shapes and films, or drawn into filaments used as textile fibers. It is malleable, having the property of plasticity. It is designed with immense variation in properties such as heat tolerance, hardness, resiliency and many others. Combined with this adaptability, the general uniformity of composition and light weight of plastic ensures its use in almost all industrial segments.

Stainless Steel
Another material of construction of pumps is stainless steel. Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings.
