Fluid Transfer Pump

Different types of fluid transfer pumps are used in a wide range of processing and handling applications, from the chemical industry, to the agricultural and mining industries and manufacturing, to name a few. A fluid transfer pump is defined by the type of pump, the material it is made of, the type of fluid being pumped, the industry or application served and the level of pressure or flow it can produce.

Traditionally, fluid transfer pumps utilised two basic types of pumping action. The first, termed dynamic action, increases the velocity of the fluid in the pump by exerting pressure on the volume of liquid. A displacement pump, in contrast, condenses and compresses the fluid by decreasing the volume of fluid. When selecting a fluid transfer pump, there are important specifications to consider that match the application you desire it for, including the maximum pressure, temperature, and power drive. It is essential to ascertain the flow capacity for the fluid transfer pump system in question.

A recent innovation is the materials used to construct fluid transfer pumps, with special regard to manually operated hand pumps. The manual force that is exerted upon the hand pump sets in motion an internal mechanism that causes the fluid contained within inside the pump to increase in pressure, whether it is water, chemicals or gases. Manually operated pumps are typical of displacement pumps, requiring that the handle is pushed to begin the pump cycle, often requiring one stroke to draw the fluid and another blow to discharge it. However, recent developments have resulted in the production of a double pumping system.

Traditionally, the main component of base construction involved the use of cast iron. However, cast iron is heavy and this weight is undesirable for hand operated pumps, which are designed to be portable. Additionally, cast iron readily conducts electricity and this characteristic is undesirable in some environments for safety reasons, as well as being an expensive input into the manufacturing process. Furthermore, the life expectancy of such pumps is significantly less when compared to similar products made from materials such as plastic. Therefore, it has been deemed desirable to not only reduce the weight of such fluid transfer devices by utilising lighter weight materials in their production, but to pass cost savings on to the consumer. The use of materials such as mouldable plastic has created a lighter, more efficient and cheaper fluid transfer pump to be available on the market.

Leading suppliers of hand operated fluid transfer pumps are utilising polypropylene and polyethylene plastics as the rugged component of construction to ensure that the pump will easily dispense a range of liquids, including strong acids, strong alkalis, cleaning chemicals, oils, lubricants, liquid food products and many other chemicals can be dispensed safely and reliably. When selecting a specific fluid transfer pump, ensure that the pump is designed with a double action pumping system, which ensures that large volumes are pumped effortlessly and efficiently, with a continuous flows being achieved.
