Little Giant pumps

Design and Operation of Little Giant condensate pumps

Little Giant condensate pumps are almost never connected in parallel – more consistently. Condensate Pumps are available with adjustable nozzle that allows you to modify the characteristics of a given manufacturer’s range. Sometimes condensate devices are used as accessories to pump air in Circulating pumps before they start.

One of the parameters characterizing the condensate pumps, a suction coefficient, or dimensionless flow rate. He is determined as the ratio of the fluid flow to the working flow. Despite its apparent simplicity and low efficiency, Little Giant VCMA-15UL condensate pumps are indispensable in many cases, for example, when you need to make an evacuation of fluid from any tanks, pumps and use a different design is not possible. Widespread use of condensate pumps were in the food industry, which together with the function of pumping liquids they performed the function of mixing different environment. Little Giant pumps are easily installed in the system plumbing pipeline, they are compact and are sometimes used on the high pressure as additional pumps.

An example of such an application can serve as sewer circulating pumps, in which the condensate pumps are used for pumping liquid from the sand traps. Another vivid example of the use of such devices can serve as a fire extinguishing system, in which water or a solution of extinguishing solution was used as the working fluid, while, as shown in pumped from a separate tank fire, more fire – the reservoir.

Condensate pumps are sometimes used with a reservoir of high pressure, which contains the working environment. Recently, condensate pumps are considered as part of the so-called Little Giant vcma-15uls, Little Giant VCC-20ULS or Little Giant vcma-15ul. Noted that the expansion of steam in the nozzle is accompanied by a decrease in temperature and vice versa – when submitting the medium under high pressure into a tapering cone last exposed to heat. Due to this property in conjunction with pumps compressors have been used in air conditioning and heating.

Design and Operation of Little Giant pumps

Perhaps, among all the hydraulic machinery Little Giant pumps can be called the most simple of designs. They have no moving parts, which are subject to wear, easy to operate and repair. Little Giant pumps belong to a class of hydraulic machines.

Simplified scheme of the Little Giant pump can be explained as follows.
Liquid, steam or gas under high pressure is fed through a tube having a nozzle in the inlet chamber. Because of the restriction nozzle liquid has a higher velocity, hence, the kinetic energy. In the inlet chamber pressure drops below atmospheric pressure, and from the supply line connected to this camera are absorbed. Both fluids enter the next chamber, where mixing and exchange of kinetic energy. Then blended substance enters the diffuser pump, which loses some of the pressure, and then – in a penstock, or holding tank.

Depending on the purpose of working, and the pumped medium can be the same (Little Giant Sump Pumps featured in this category include Little Giant 6-CIA series, 6-CIM series, 6-CIA, 10-CIA, TSW-SP, ES33 and others), or different. Jet pumps belong to the so-called “Dynamic pumps. The main disadvantage of such pumps is the low efficiency – up to 30%.

Striking is the fact that prior to the application of Taco pumps as a source of mechanical energy, ie until the 19 th century, the jet pumps are widely used as a generator of hydraulic energy.
