Piston Pump
The MK FLOW Piston Pump is a positive displacement pump designed to deliver high-pressure and high-accuracy fluid transfer. Using the reciprocating motion of one or more pistons inside a cylinder, it is ideal for applications involving high pressure, viscous or abrasive fluids, and where metered or pulsating flow is acceptable.
These pumps are used in industries such as hydraulic systems, oil & gas, water jet cutting, chemical dosing, and cleaning systems.
⚙️ Working Principle
Piston pumps operate by a reciprocating piston moving back and forth inside a tightly sealed cylinder. On the suction stroke, the piston moves back, creating a vacuum that draws fluid into the chamber. On the discharge stroke, the piston pushes the fluid out at high pressure. Check valves prevent backflow, ensuring unidirectional fluid flow.
