What is a manual water pump?
After helping you choose the most suitable pump for the use you need in a blog article , let's focus on the manual water pump . How do they work? What types exist? Below we explain everything you need to know.

Manual water pump: what are they?

A hydraulic pump or manual water pump is an appliance constructed to extract water from a cavity where a well is needed, for example. It serves to pump a fluid that is at a lower level, towards a surface. These types of pumps are activated thanks to the human manual force.

How do they work?

The operation of the manual water pump is based on mechanical energy. The valve that pumps the water you want to move is activated by moving the lever up and down. With the movement up, the valve goes down and the liquid enters the pump cavities. By operating the lever down, we make the water rise and with the repetition of the movements, a flow is created towards the surface.

What are they used for?

We can find the manual water pump in different sectors, from factories or industrial companies to private homes. Let's see some examples of its use:
  • Well or kitchen countertop to house a home
  • Empty a pool, raft or waterlogged site
  • Irrigation of farmland
  • Watering private gardens
  • Water drainage in industries


There are several types of manual water pumps. Here are the characteristics of the 4 main ones:
  • Siphon: This type of manual water pump is very simple and is used to transfer liquids quickly and as cleanly as possible. It is used to pump water, gasoline, to solve clogged toilets…. It is a suction pump and consists of a PVC pipe. It is not necessary to install it on a surface and has a capacity limited to its use.
  • Direct action: They are those that have a lever to pump the fluid up and down. We have described its operation above. It is the action of the lever that allows the plunger to lower and rise until the water is pumped to the surface.
  • Deep wells: These are the ones we will need if we want to extract water that is more than 15 meters deep. They are heavier and more complex than the rest. They are operated by a steering wheel or a lever.
  • Diaphragm: They are easy to operate because the bars to be moved allow greater force.


With the use of this kind of manual water pumps, you do not depend on running light. And in case of failure of the distribution network, the use of the manual water pump is intact. This is a benefit if your home or business is in a place with restricted access to the current or suffering from habitual failures.
  • They are easy to use.
  • They are easy to install.
  • If you are a professional or have a job, you could make it yourself for domestic use
  • If the materials with which it is made are galvanized iron and PVC plastic, the parts of the pump are prevented from deteriorating


  • They can be easily damaged, but can be fixed by hand by disassembling them completely. Maybe the process is a bit cumbersome, but being all mechanical possible damage can be fixed.
  • Its use is concrete and for a small depth.

A manual water pump as you see, is mechanical and simple to use.
