What is a Diaphragm Pump?

Diaphragm pumps, also known as membrane pumps, are a type of pneumatic positive displacement pump. They can transfer low, medium, and high-viscosity liquids, as well as liquids with suspended solids, by using compressed air, hydraulics, or electricity and rotating parts to create a temporary chamber that draws in and expels liquid for efficient fluid flow and processing. Available in various configurations to suit the exact needs of your applications, diaphragm pumps can be manufactured with a variety of body materials and diaphragms.

How Does a Diaphragm Pump Work?

Hydraulic drive, electric, and air-operated diaphragm pumps feature flexible diaphragms mounted to a shared shaft that moves back and forth continuously to pump fluids. In this type of pump equipment, the driving mechanism begins the cycle. The first stroke, or the intake, pushes the diaphragm away from the pump chamber to create a vacuum and bring in fluid through the inlet. Then, the second stroke forces the opposite diaphragm toward the chamber, compressing the fluid and pushing it through the outlet. This process continuously repeats to complete the fluid transfer or processing operation.

Diaphragm Pump Parts and Repair Kits

Standard-duty and heavy-duty flap valve diaphragm pumps offer performance requirements to suit many fluid transfer and processing applications. To simplify the maintenance of your diaphragm pumps, find industrial solutions, direct replacement pump parts, or repair kits for the following components:

• Diaphragms and pump chambers
• Inlet, outlet, check, and pressure relief valves
• Compressed air or hydraulic drive systems
• Pistons and shafts
• Mounting frames
• Discharge manifolds

Common Applications of Diaphragm Pumps

Engineered to be a standard pump for various applications, diaphragm pumps can handle many fluid-handling operations across a range of industries. They are compatible with processing chemicals, solvents, viscous or sticky fluids, fluids with suspended solids, slurries, creams, gels, and oils to meet your requirements. Diaphragm pump applications include:

• Ceramics
• Coating and paint formulation
• Chemical processing
• Electroplating and anodizing
• Pulp and paper manufacturing
• Oil, gas, and mining operations
• Water and wastewater treatment
