A Victorian-era pump organ A smaller variety of pump organ A Mason & Hamlin pump organ A pump organ. The harmonium was considered by Curt Sachs to be an important instrument for music of Romanticism (1750s–1900), which "vibrated between two poles of expression" and "required the overwhelming power and strong accents of wind instruments".

The skeletal muscle pump. The skeletal muscle pump or musculovenous pump is a collection of skeletal muscles that aid the heart in the circulation of blood. It is especially important in increasing venous return to the heart, [1] but may also play a role in arterial blood flow.
The Indian harmonium is derived from reed organ designs developed in France. Originally, these were large instruments, designed to be played sitting on a chair, which allowed one to pump the instrument using foot pedals. [4] Over time, Europeans designed smaller harmoniums, like the guide-chant, which included manually pumped bellows. [5]
Musicians with cornua and a water organ, detail from the Zliten mosaic, 2nd century CE. The water organ or hydraulic organ (Greek: ὕδραυλις) (early types are sometimes called hydraulos, hydraulus or hydraula) is a type of pipe organ blown by air, where the power source pushing the air is derived by water from a natural source (e.g. by a waterfall) or by a manual pump.
Estey started production in 1850 with about 75 instruments per year. [5] After a flood threatened his downtown factory, Estey built a new factory on Birge street.

From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
They normally use either a centrifugal pump or an axial flow pump. Both types have a central rotor containing permanent magnets. Both types have a central rotor containing permanent magnets. Controlled electric currents running through coils contained in the pump housing apply forces to the magnets, which in turn cause the rotors to spin.
