This pump is used for hand lotions, i.e. thick (high viscosity) liquids. |
|
There are two metal balls inside this pump. The large lower ball fits inside
the first few turns of the spring. The middle turns of the spring are of
reduced diameter so they act as a stop for the ball. |
| This particular
version of hand pump is patented by Calmar, Inc. though many fairly similar
pump mechanisms exist. |

This is a still representation
and possibly also a low-resolution image of a fully animated pump.
