Diaphragm Pumps
Sandur Fluid Controls Pvt. Ltd. offers a comprehensive range of high-performance Diaphragm Pumps engineered for efficient, leak-free, and reliable fluid transfer across diverse industrial applications. Designed for handling chemicals, corrosive liquids, viscous fluids, slurries, solvents, and sensitive media, these pumps provide exceptional durability, safety, and operational efficiency.
Diaphragm Pumps are widely used in chemical processing, water treatment, pharmaceuticals, food & beverage industries, mining, oil & gas, paint manufacturing, wastewater treatment, and industrial fluid handling systems.
Our pumps are available in air-operated double diaphragm (AODD), electrically driven diaphragm, and metering diaphragm configurations to suit low-pressure, high-pressure, and precision dosing applications.
Diaphragm Pumps are positive displacement pumps that use a flexible diaphragm and check valves to move fluids through suction and discharge cycles.
The diaphragm reciprocates mechanically, pneumatically, or electrically, creating pressure differences that draw fluid into the pump chamber and discharge it efficiently.
Since the pumped fluid is isolated from moving mechanical parts, diaphragm pumps offer excellent leak prevention, chemical resistance, dry-run capability, and safe handling of aggressive or hazardous liquids.
These pumps are ideal for applications requiring self-priming, solids handling, low-shear pumping, and contamination-free fluid transfer.
