What is a water pump?

A water pump is a device for pumping and moving water. All types of pumps are used but they are tailored to the physical properties of the medium. Typical constructions are the piston pump, the plunger pump, the Archimedean screw, the centrifugal pumps in various designs and the hydraulic ram. The water pump in the form of a scoop wheel is probably the oldest of all pumps. Water pumps allow the settlement of arid areas and are widespread. In pumped storage power plants, water pumps are used for energy storage.

Brief history of water pumps

Already in ancient times reciprocating pumps were used by the Greeks and the Romans to promote water. In the Netherlands, water pumps were used in the 13th century to drain the cities.

Water pumps for engine cooling in vehicles

Coolant pumps (old water pumps) are located in any liquid-cooled internal combustion engine to circulate the coolant. Mechanical coolant pumps are driven in vehicles and stationary engines via V-belts, flat belts (Polyrib), toothened belts of gears. The flow rare is dependent on the engine speed for uncontrolled coolant pumps. A coolant pump in a truck typically requires a power of up to about 7 kW. With and electromagnetic clutch (on the market since 2009) between 0.5 and 1.5 percent of the fuel can be saved by needs-based control.

Two little-known facts about water pumps

1: Every house has its own unique needs. Not every water pump will work in every water tank. You have to make sure that your water pump suits your house and water pressure best. If you are not sure, the best thing to do is to have a specialist look into the matter.

2: The average life span of a submersible pump is ten years. If you’re submersible pump is older than that, you might have to buy a new one.
