How does a cylinder pump operate in a Fish Tank?

A motor is connected by a leather belt to a flywheel. As the flywheel turns, it actuates a piston which forces air out through a cylinder. Some larger models have two cylinders with the flywheel located between them. As one piston enters its cylinder the other is withdrawn, thus providing a continuous flow of air. The amount of air and the air pressure delivered by a cylinder pump are determined by the size of the cylinder, the speed of the motor and the size of the flywheel. The standard motor is from 1/150th to 1/75th horsepower. The volume of air given off by a cylinder pump can, in some models, be regulated by adjusting the angle at which the piston enters the cylinder.

First of all - power. Cylinder pumps deliver considerably more air and give more pressure than the diaphragm type. They are less subject to breakdowns, and can usually be repaired by the owner with replacement parts, which are available at the pet shop. This eliminates the delay and inconvenience required for sending the pump back to the manufacturer for repair.

When purchasing a cylinder pump, always ask for a manufacturer’s instruction sheet, which details the proper oiling and adjustment procedures for oil holes while turning the motor by hand. Continue this until the cleaning fluid runs through clean. Allow several Fours for the carbon tetrachloride to dry completely both inside and out. Make sure that the motor is re-oiled before being put back into use. The cleaning fluid, of course, will have removed all the oil as well as the dirt.
