Efficient Industrial Pumps with Stupendous Features
Pumps are used in most of the industries for various purposes. Pumps that are used in industries must have better efficiency to perform the works in a faster way. However, small problems such as leakage may considerably reduce the performance of the pumping system. To resolve the leakage problems, presently mechanical seals are used due to its efficiency in completely fixing the leakage problem, but this process is quite expensive, while on other hand we can use packing that is less expensive but may not last longer. Besides, frequent maintenance is needed for better performance. There are different types of industrial pumps that vary in the mode of operation.
Some efficient industrial pumps are listed below:
Positive Displacement Pumps:
It has an expanding cavity on the inlet side and a decreasing cavity on the discharge side. It operates by forcing a fixed volume of fluid that from the suction pressure section of the pump into the discharge zone of the pump. These pumps are known as constant flow machines, because they are capable of providing constant flow of fluid without any decline in the intensity of the flow. These types of pumps are used frequently in hydraulic systems. Some basic types of positive replacement displacement pumps are reciprocating, metering and rotary pumps.
Centrifugal pumps:
It operates by converting the energy of electric motors into kinetic energy. The kinetic energy is then used to generate the pressure that is needed to pump the fluid. The impeller is the rotating part that is responsible for the conversion of electric motor energy into kinetic energy. Fluid enter the inlet of the pump and then passes to the impeller which rotates producing the centrifugal acceleration and when the fluid leaves the impeller a low pressure area is created, which is required to allow more fluid to enter the inlet. These types of pumps are used in large numbers worldwide, due to its efficiency and longer lifespan. If there are two or more impellers then they are known as multistage centrifugal pumps. Connecting the impellers in series will increase the pressure at the outlet, while parallel arrangement enhances the higher flow output.
Air driven pumps:
As the name implies, these types of pumps use the compressed air to operate the pumping operation. Air driven pumps are used to pump most of the fluid types and are used mainly in flammable gas pumping, because this pump doesnt require electricity for its working therefore during gas pumping there are very less possibility for damages. Compressed air helps to maintain a constant flow of the fluid without any barrier. It also uses rotor and diaphragm for the effective movement of the fluid.
These are the efficient industrial pumps that are frequently used in most of the industries.

A heat pump driven by a 0.4 kW electric motor provides heating for a building on a day
when the outside air is –10 °C and energy is lost through the walls and roof at a rate of 16000
kJ/h. What is the maximum theoretical temperature that this heat pump can maintain within the
building, in °C?
W = 0.4 kW
Tc = -10 deg. C = 263 K
Q_h = 16000 kJ/h = 4.4444 kW
η_max = Qh / W = Th / Th-Tc
4.4444/0.4 = Th / Th-263
11.1111 * (Th - 263) = Th
Th = 289 K
Th = 16 deg. C
