What are types of Piston Pumps ?

Published by Industrial Pump Parts Hamilton, Ontario Canada

Piston pumps are a type of positive displacement pump that uses a reciprocating motion to move fluid from the inlet to the outlet. They are commonly used in a variety of applications, including industrial, agricultural, and commercial settings. The following are the main types of piston pumps: 

1. Single Acting Piston Pumps: These pumps use a single cylinder and a piston that moves back and forth to create suction and discharge pressure. The fluid is drawn into the cylinder on the upstroke of the piston and is expelled on the downstroke. 
2. Double Acting Piston Pumps: These pumps use two cylinders, each with its own piston. The pistons move in opposite directions, creating suction on both the upstroke and the downstroke. This type of pump can handle higher fluid flow rates than single acting pumps and is typically more efficient. 
3. Axial Piston Pumps: These pumps use a number of pistons that are arranged in a circular pattern around a rotating drive shaft. As the drive shaft rotates, the pistons move in and out, creating pressure and suction. Axial piston pumps are often used in high-pressure applications and are known for their durability and reliability. 
4. Radial Piston Pumps: These pumps are similar to axial piston pumps, but the pistons are arranged radially, rather than in a circular pattern. They are typically used in applications that require high flow rates, such as water treatment or hydraulic power transmission. 
5. Diaphragm Piston Pumps: These pumps use a flexible diaphragm, rather than a piston, to move fluid from the inlet to the outlet. The diaphragm is actuated by a pressurized fluid, which moves the diaphragm back and forth, creating suction and discharge pressure. Diaphragm piston pumps are often used in applications that require a gentle handling of the fluid. 

In conclusion, there are several types of piston pumps, including single and double acting piston pumps, axial and radial piston pumps, and diaphragm piston pumps. Each type of pump is designed for specific applications and has its own unique features and benefits. When choosing a piston pump, it is important to consider the specific needs of your application, such as flow rate, pressure, and fluid type.
