A basic gar pump features a rotary housing containing 2 or more gears; that is toothed wheels, helical gears or lobed cams. Tight tolerances are required between the casing and gears, bore and gears and also between the gears. Typical housing will have an inlet and outlet, for suction and discharge respectively. The 2 main types are; external gear pumps, which use two external gears and internal gear pumps which use internal and external gears. The term positive displacement for gear pumps describes the fixed amount of fluid they move for each revolution.
In the lubrication industry, a fluid management system is comprised of various fluid control components which meter, monitor and dispense oil and other lubes. Technicians dispense a huge amount of bulk fluid which makes it very critical to keep it in check, whether on the field, workshop or fleet service centres: every drop counts.
Mechanical engineering has evolved significantly, not only in advancements, but also in health and safety, environmental aspects, reliability and sustainability.
Competition among suppliers is also noted, with available suppliers exceeding market demand. Competition between customers also influences their choice of equipment used, with grease emphasis on productivity, reduced operating costs, quick return in investments, health and safety, and profits.
An air-operated pump is a positive displacement reciprocating pump utilized for the general transfer of liquids, and is driven by means of a compressed gas from an outside source. The compressed gas that’s used within an air-operated pumps is normally just air, and the directional flow of the internal process liquid is produced from suction and discharge check valves. Air-operated pumps are utilized in different industries, including petrochemical and food and beverage facilities, along with wherever else they are needed.
