Pistonpompen

Pistonpompen, also known as reciprocating pumps, are a type of positive displacement pump that utilizes a piston moving back and forth within a cylinder to move fluids. This reciprocating motion creates changes in volume within the cylinder, drawing fluid in during one stroke and expelling it during the next. The core components of a piston pump include a cylinder, a piston, a connecting rod, a crankshaft, and inlet and outlet valves. The crankshaft converts rotational motion into the linear motion of the piston via the connecting rod.

As the piston moves away from the cylinder head, it creates a partial vacuum, causing the inlet valve to open and fluid to be drawn into the cylinder. On the return stroke, as the piston moves towards the cylinder head, the inlet valve closes, and the outlet valve opens, forcing the fluid out of the cylinder under pressure. The operation is inherently cyclical and can generate significant pressure. Piston pumps are commonly used in applications requiring high pressures or precise flow rates, such as in hydraulic systems, oil and gas extraction, and in some types of industrial metering. They are known for their efficiency and durability, though they can be prone to wear due to the sliding action of the piston. Maintenance often involves checking and replacing seals and valves.
