A Complete Guide to Diaphragm Pump

The diaphragm pump is a versatile tool in various industries. From mining to wastewater treatment, they can handle a wide range of fluids, including the highly toxic corrosive ones. It makes them the first choice for fluid handling. In this guide, we will understand what exactly a diaphragm pump is and how it functions.

So, a diaphragm pump is a kind of positive displacement pump that uses a flexible diaphragm to create a reciprocating action, which moves the fluid in and out of the chamber. It is their unique mechanism that makes them suitable for handling fluids of different viscosities and even toxic chemicals.

Working Principle of the Diaphragm Pump

Inlet:

When the pump is not functioning, it is in a relaxed state. Once the connection is activated, the inlet valve opens, and it allows fluid to enter the pump chamber.

Displacement Phase:

A mechanical system consists of the connecting rods and an air distribution system, which starts to move the diaphragm to compress the fluid in the pump chamber.

Outlet Phase:

As the diaphragm compresses the fluid, the outlet valve opens. It allows the fluid to be expelled from the pump chamber. It creates a steady and efficient flow of the fluid.

Reciprocating Phase:

Once the fluid is discharged, the motor is relaxed, creating a vacuum in the pump chamber. It opens the inlet valve again, and the fluid transferring session keeps repeating. 

This reciprocating action of the diaphragm pump makes it suitable for a wide range of viscous fluids, abrasive, and those which are chemically aggressive.

Types of Diaphragm Pumps

There are different kinds of diaphragm pumps available. Each one has specific features and specifications, which make it different from the others.

Air-Operated Diaphragm Pumps (AODD):

These pumps function on compressed air. They are widely known for their versatility and ability to handle different fluids.

Mechanically Operated Diaphragm Pumps:

These pumps are driven by a mechanical mechanism such as cams, gears, and hydraulic pistons. They are mostly used for specialized applications.

Hydraulic Diaphragm Pumps:

These fluid transferring pumps run on hydraulic power, which makes them ideal for heavy-duty applications.

Electromagnetic Diaphragm Pumps:

They are heavy-duty operations known for their precise and consistent control flow.

Benefits of the Diaphragm Pumps

There are so many benefits of using the fluid transferring pump.

Flexible:

It is a versatile tool which can handle a wide range of fluids, be it water to thick slurries and toxic chemicals.

Self-Priming:

Their self-priming feature allows the fluid to be drawn to enter the pump without any external priming.

Safe Operations:

Their ability to isolate the fluid from the environment makes it suitable for handling the toxic materials effectively.

Accuracy:

The advanced features allow precise fluid control, allowing the precise flow control over the fluid. It makes them suitable for applications where precise operations are needed.

Cost-Effective:

They are known for their durability. Making this sturdy material reduces the maintenance needs. It reduces the operational cost, making it a cost-effective and highly effective industrial solution.
