    Tips: Types of piston pumps

    The two main types of piston pumps are lift pumps and force pumps. Both types can be operated by hand or engine.

    Lift pumps

    In a lift pump, the upward stroke of the piston draws water into the lower part of the cylinder through a valve. In the downstroke, the water enters the upper part of the cylinder through a valve set in the piston. In the next upstroke, water is discharged from the upper part of the cylinder through a nozzle. This type of pump is limited by the height of water that can be supported by air pressure against vacuum.

    Force pumps

    In a force pump, the upper stroke of the piston draws water through the inlet valve into the cylinder. In the downstroke, the water is discharged through the discharge valve into the discharge pipe.
