subject: Pumps And Pumping Equipments To Carry Out The Diverse Task In Industrial Sector [print this page]


Pumping of liquids is almost universal in chemical and petrochemical processes. Different materials being processed require close attention to selection of materials of construction of the various pump parts, shaft sealing, and the hydraulics of the individual problems. A wide variety of pumps types have been developed to satisfy the many special conditions found in chemical plant systems like Solenoid Pump. A pump is a physical contrivance that is used to deliver fluids from one location to another through conduits. Over the years, numerous pump designs have evolved to meet differing requirements.

The basic requirements of pumps to define the application are suction and delivery pressures, pressure loss in transmission, and the flow rate. Special requirements may exist in food, pharmaceutical, nuclear, and other industries that impose material selection requirements of the pump. The primary means of transfer of energy to the fluid that causes flow are gravity, displacement, centrifugal force, electromagnetic force, transfer of momentum, mechanical impulse, and a combination of these energy-transfer mechanisms. Gravity and centrifugal force are the most common energy-transfer mechanisms in use. Triplex piston pump operate with approximately constant capacities over wide variations in head; hence, they usually are installed for services that require high heads at moderate capacities.

In general, a pump refers to a machine or device used for lifting, compressing, or transferring fluids. It is mainly used for transport of liquids, including water, oil, acid, alkaline liquid and liquid metals. In addition, it can also carry mixtures of gases and liquids containing solids in suspension. A pump displaces a volume by physical or mechanical action. There are three major types of pumps groups: direct lift, displacement, and gravity pumps. Their names describe the method for moving a fluid. An increase in pressure takes place in pumps, fans, compressors and propellers. The pumps are divided into two fundamental types based on the manner in which they transmit energy to the pumped media: kinetic or positive displacement.

Pumps are used throughout the world for a variety of purposes. Earlier there applications included the use of the windmill or watermill to pump water. Today, pumps are used for irrigation, water supply, gasoline supply, air conditioning systems, refrigeration (usually called a compressor), chemical movement, sewage movement, flood control, marine services, etc. Pump designs have largely been standardized. Positive displacement pumps are either reciprocating or rotary. Reciprocating pumps include piston, plunger, and diaphragm types. Rotary pumps are single lobe, multiple lobe, rotary vane, progressing cavity, and gear types.

Pumps are used to meet the variegated demand of various manufacturing and production industries. Solenoid Pump is manufactured with premium quality standards. This pump has the advantages of adjustable and prcised flow rates when averaged over time. Triplex Piston Pump is known for its easy operation, low power consumption and durability.
