A lift pump is a pump that lifts a liquid rather than forcing it through a system. They often have no internal motors, impellers, or regulated valve systems and use natural or mechanical forces to move water up through a pipe system. A force pump and a piston pump are two types of lift pumps that are widely used in rural areas. They use less energy and require less maintenance than pusher systems.
A lift pump is any type of pump that lifts a liquid rather than forcing it through a system. These pumps are often completely mechanical in their operation; they have no internal motors, impellers or regulated valve systems. Many of these pumps have partially sealed chambers that create suction systems or bent tubes that hold a liquid read to the siphon. A common example of a lift pump is the style of water pump common on many beaches and campgrounds – they run totally on suction and physical lift.
Most pumps work with a motor that pushes a liquid forward. When the pump is running, the water around the motor moves forward and creates a low pressure area behind it. Water behind the engine rushes forward to fill the void, only to be pushed through the system. This creates a flow towards the water, but is forcibly maintained by the pump.
The pumps that work on the physical lift work differently. They use one or more natural or mechanical forces to move water up through a pipe system. These pump systems often displace less water than a pusher system, but generally use much less energy and require less maintenance. Furthermore, they can operate in areas with little infrastructure without any impact on their ability to function.
A force pump is a lift pump widely used in rural areas of the United States. This type of lift pump can be found in many unpowered homes, campgrounds, and hiking trails. A common force pump consists of a buried pipe and an above ground piston and handle. When a person pumps the handle, it creates negative pressure in the hose and pulls the water to the surface.
When the water reaches the surface, it enters the lower piston chamber. A valve at the bottom of the piston closes due to the weight of the water, and a valve on the piston itself opens to relieve pressure as you push down. This valve allows water to enter the upper chamber and exit through a spigot on the side of the pump. At this point, more water has entered the lower chamber and the process repeats.
A piston pump is a type of lift pump that runs on water pressure alone. One pipe is set on a downward slope to aid in the natural flow of water. When the water in the hose hits a plug in the pump, it temporarily builds in pressure. This pressure opens a valve in the pump and a small amount of water flows before the pressure equalizes and the valve closes. Closing the valve triggers a restart of the sequence and water is slowly moved through the system.
