The main function of a utility pump is to pump large quantities of liquid as quickly as possible.  These devices are not, however meant to work continuously.  They may work on a particular timer or valve system whereby they pump water as required.  Most often, the utility pumps sold are manufactured from plastics such as thermoplastic or stainless steel which is housed in a lightweight and durable housing.

There are essentially two different types of utility pumps.  Those that are designed to pump abrasive materials such as chemicals, hazardous waste, highly viscous fluids, diesel fuel and gasoline as well as corrosive acids.  The other type of pump is designed to pump water, sewage and wastewater.

When selecting the right pump for yourself, there are a few key factors to take into consideration:-

1.  Choosing an automatic pump versus a manual system pump.  For manual systems, you are required to switch the pump on and off as you require it, whilst automatic pumps will turn on and off automatically as determined by water levels.  There are various switch devices including the pressure switch, low level pressure switch and float switch.

2.  The amount of horsepower that is available ranges from one quarter horsepower to extensive horsepower supply.

3.  Pressure is required to move the liquid.  The head pressure is defined as the expression of a pressure in terms of the height of fluid.  The equation looks like this p=ypg, where p is liquid density and y is the fluid column height.

Types of Utility Pumps

Dewatering Pumps are generally used for water pump applications.  It works best when moving liquid that has a maximum solid concentration of ten percent and a maximum solid size of less than twenty five percent of the diameter of the inlet.

Trash pumps are used for handling materials that have a higher solid concentration.

Centrifugal pumps make use of a centrifugal force to generate velocity.  Impellers that rotate are then used to increase this velocity in order to push the fluids through the outlet valve.  Magnetic drive pumps operate by way of an electromagnetic drive.

Hand pumps will generally have a lever or a handle that will require manual rotation in order to pump the liquid and Siphon pumps are also manually operated.  They make use of the gravitational flow, while drum pumps are manufactured to dispense the liquid contents of drums and tanks.

Various other pumps include:-
Fountain pumps
Pool pumps
Micro pumps
Bilge and ballast pumps
Refuelling pumps
Sump pumps
Water and Well Water Pumps

Features of Utility Pumps:-

When looking for a utility pump, you may want to look at the following features to ensure that you get the right performance level for your requirements.  Adjustable speeds will allow you to operate the pump at the optimum speed you require.  You can also choose a continuous duty pump which will continue to run for a 100% duty cycle.  Self-priming pumps maintain a vacuum that is able to draw fluid into the inlet without external assistance, but for the most part, your utility pump will include a battery backup, level control device, thermal overload protection or suction.

Prior to purchasing your utility pump look at the following specifications.  The inlet size is important when considering the material that you are going to be pumping as well as the overall discharge pressure and flow.  Your options for various power supplies will include alternating current, direct current, compressed air, diesel, gasoline, natural gas, solar energy and hydraulic systems amongst others. Alternatively you may opt for manual powered systems that will require foot or hand power.
