Metering Dosing Pump
A pump is basically a device that is used to move fluids, liquids or gases from one level or place to another. Pumps are commonly used in homes, schools, colleges, offices, hospitals, factories etc.; including refrigerators, air conditioners, power plants, cars, ships and airplanes.

Today several suppliers offer metering dosing pumps; which is a positive-displacement device used for chemical dosing. They control the flow capacity of fluids manually or automatically; as per specific requirements with a high level of repetitive accuracy.

Metering pumps are used for hydrocarbon processing, power generation and waste water treatment. They have the ability to pump a wide range of chemicals in processing plants that includes acids, bases, corrosive or viscous liquids, slurries and all other fluids.

Rotary Gear Pump

Nowadays, pump manufacturers provide various types of pumps for residential, commercial and industrial applications; including rotary gear pumps. Gear pumps are fundamentally positive displacement devices used for transporting voluminous liquids under high pressure.

They consist of two or more gears that create vacuum pressure and push the fluid. There are two main varieties available such as external gear pumps that use two external spur gears; and internal gear pumps that use both an external and an internal spur gear.

Rotary gear pumps are used to transfer several viscous fluids like crude oil, lube oil, diesel, kerosene etc. for fuel oil systems; vegetable oils, fatty acids, molasses, soap stocks; hot oil, fuel oil and bitumen in road construction equipment.

Reciprocating Pump

Reciprocating pumps push fluids using oscillating pistons, diaphragms or plungers; and are driven by air, steam or motor. These pumps consist of one or more cylinders; and hence termed as simplex for independent suction and discharge strokes; or duplex for double suction and discharge in both directions.

Windmill water pump, hand pump, axial piston pump etc. are reciprocating pumps manufactured for propelling highly viscous fluids having low flow rates against high pressure; including concrete and heavy oils, as well as for hydro testing of valves, tanks, piping and vessels for hydro jetting.
