Diaphragm Sprayer Pump
Diaphragm sprayer pumps are positive displacement pumps that use a flexible diaphragm and check valves to transfer liquids, making them ideal for spraying water, chemicals, and viscous fluids with reliable pressure and self-priming capability.
Overview
A diaphragm sprayer pump, also known as a membrane pump, is a positive displacement pump that operates using the reciprocating movement of a flexible diaphragm combined with inlet and outlet valves. This design allows efficient and controlled fluid transfer without direct contact between moving metal parts and the pumped fluid.
Operating Principle
The diaphragm moves back and forth inside the pump housing, creating alternating suction and discharge phases. During suction, fluid is drawn into the chamber through a check valve. During discharge, the diaphragm pushes the fluid out through the outlet valve, generating consistent pressure for spraying applications.
