What is a hand pump?
A hand pump is a manually operated pump that requires no electricity. Each up-and-down stroke of the handle drives a piston mechanism that draws water and delivers it to the outlet. It is used to draw water from shallow wells, cisterns, and tanks, for irrigation in gardens and vineyards, and for water supply in rural areas without electricity or in emergencies. Cast iron body pumps can be used for many years thanks to their durable construction.
Category contents
- Threaded-connection pumps: Mounted to the suction pipe with a threaded connection.
- Flanged-connection pumps: Provide a secure installation via a flange.
- Different sizes: Values such as 32, 40, and 50 in product names indicate the pump's size class, while measurements such as 1 and 1 1/4 inch indicate the connection diameter.
Suction limit and installation
Because hand pumps draw water by suction, they are subject to the suction lift limit imposed by atmospheric pressure; in practice, efficiency drops sharply and suction becomes impossible when the water level is more than a few meters below. They are therefore suitable for shallow wells and tanks close to the surface. Fitting a foot valve to the end of the suction pipe keeps the pipe filled with water and ensures the pump delivers water immediately at each use. The pump should be bolted to a well cover or a solid base.
Use and maintenance
On first use or after the pump has stood idle for a long time, pouring a small amount of water into the top wets the piston seals and starts the suction. The piston seals can wear over time; if suction weakens, the seals must be replaced. During winter, water should be drained from the pump to prevent freezing. Moving joints should be lubricated regularly.
Frequently asked questions
How deep can a hand pump draw water from?
Suction lift is limited; submersible pumps or deep-suction pumps should be used for deep wells.
Why isn't the pump delivering water?
An air leak in the suction pipe, dried-out seals, or a leaking foot valve are the most common causes.
Is it necessary to pour water in on first use?
Yes; pouring a small amount of water in from the top to wet the seals makes it easier to start suction.
What pipe should be used?
A rigid pipe or spiral hose that matches the pump's connection size and does not collapse under vacuum should be used.
Is a hand pump suitable for drinking water?
The potability of the water source must be verified separately; the pump only conveys the water.
What can be used instead of a hand pump where electricity is available?
Where electricity is available, jet pumps are a more practical solution.
