Be Self Sufficient With Hand Water Pumps

!: Be Self Sufficient With Hand Water Pumps

What would you do if the water in your home, one day, stopped running from the faucet? But it wouldn't only be you - the water would be shut off from all of your neighbors' houses, as well. With no water source and no grocery store for miles, what would you do in that instance, except for wait?

When you depend on the traditional system of pipes and faucets, such an instance is bound to happen, even if brief. Instead of expecting this dependence over time, however, consider an alternative - hand water pumps. Although used as a backup for traditional motorized designs, these hand pumps allow you to manually bring up water from a source below ground, such as an aquifer. Such a system does not rely on electricity and can bring up more than a day's supply of water.

Pumps, hand or electric, have a jet or submersible design for bringing water up from a shallow or deep source. Shallow pumps have a jet design and are mounted above a well. This system brings up water through a suction motion, much like when you suck on a straw. Limited to a depth of 25 feet, these water pumps need to be filled already through a one-way check valve to start working.

Water pumps for deep wells also have a jet design. To go a greater depth, however, the system uses two pipes, both of which use suction and pressure to lift water.

Submersible pumps are more efficient for deeper wells. Made with a long cylindrical shape in a well casing, these water pumps are primarily underground. The bottom half is a sealed pump below ground that is connected to a power source on the surface.

Hand pumps can be used with shallow and deep wells. Simple Pump, one of the more well-known manufacturers of hand pumps, has a manual design that brings up water at five gallons per minute from a few hundred feet below ground. Although a hand pump can back up a motorized system, it can also be used on its own.

Submersible Pumps

!: Submersible Pumps

A submersible pump is one that has a sealed motor, fitted in a pump body. The total assembly is immersed in the fluid that needs to be pumped. The main advantage of this type of pump is that it can offer a considerable amount of lifting power, as it does not rely on external air pressure.

A submersible pump has a system of mechanical seals that is used to prevent the fluid being pumped from entering the motor, resulting in a short circuit. A pump can either be attached to a pipe or a flexible hose.

Some of the types of submersible pumps are bladder pumps, bilge and ballast pumps, borehole pumps, booster pumps, and centrifugal pumps. Other examples are condensate pumps, dewatering pumps, fountain pumps, grinder pumps, micro pumps, sampling pumps, trash pumps, utility pumps, and well pumps. Some submersible pumps are manufactured for particular applications. These pumps are water submersible pumps, sewage submersible pumps, 12-volt submersible pumps, sand submersible pumps, irrigation submersible pumps, and solar submersible pumps. Solar submersible pumps have many uses and are suitable for slow and steady water transfer into a holding tank.

Submersible pumps are found in many appliances. Single stage pumps are utilized for drainage, sewage pumping, common industrial pumping, and slurry pumping. Multiple stage submersible pumps are normally used for water abstraction. These pumps can also be found in oil wells. Moreover, submersible pumps can be positioned directly in a pond and require comparatively little installation. These pumps are also relatively silent.

The four main specifications that should be considered while choosing a submersible pump are maximum expulsion flow, maximum discharge pressure, horsepower, and discharge size.

Earlier, the main drawback of submersible pumps was that its pump seal could rupture and release oil coolant into the water. However, newer pumps are magnet-driven, and no longer require a coolant. These magnet-driven pumps are more expensive, but they consume less electricity.
