Diaphragm Pump


Diaphragm pumps

Diaphragm pumps are mechanical devices used to move fluids. They are particularly useful for transporting corrosive, viscous liquids, or those containing suspended solids.

They operate through a flexible membrane that moves back and forth, creating pressure that draws the fluid from one side and pushes it out the other. This motion is controlled by a mechanism that can be operated manually or with electric motors.

FLUIMAC diaphragm pumps are made of PP, PVDF, ALUMINUM, and AISI 316.

Components

A Diaphragm pump consists of several key components that allow it to function. Here is a list of its main components:

Pump body: The external structure that contains and protects the internal components. It can be made of various materials, including corrosion-resistant metals or industrial polymers, depending on the application.
Membrane: The heart of the pump, this flexible membrane expands and contracts to create the movement of fluid. The choice of material (such as PTFE, nitrile rubber, or EPDM) depends on the chemical compatibility with the fluid being pumped.
Inlet and outlet valves: Control the flow of fluid into and out of the pump, preventing backflow. They can be of various types, such as ball or flap valves, selected based on the nature of the fluid and the required flow precision.
Pumping chamber: The space where the membrane moves to draw in and push out the fluid. Its configuration is essential for pumping efficiency.
Drive mechanism: The system that moves the membrane, which can be pneumatic (using compressed air) or electric. The pneumatic mechanism is often preferred for its simplicity and for use in hazardous environments.
Control system: Electronic or mechanical components that regulate the pump's speed and pressure, allowing for precise fluid dosing. Includes sensors to monitor operating conditions.
Hydraulic connections: Inlets and outlets for connection to piping systems. The choice of material and design depends on the operating pressure and chemical compatibility.

How a Diaphragm Pump Works

A diaphragm pump is a technological jewel. Its operation is a precise and efficient mechanism, the result of careful study. The mechanics of these machines and the ways in which they are able to function in every situation and with any type of liquid are interesting.

Diaphragm pumps consist of a double chamber which serves for the transit of liquids set in motion by the oscillation of a diaphragm.

The operation consists of two consecutive cycles that are repeated alternately, allowing the liquids to be sucked in and subsequently moved towards the delivery. Suction and delivery follow one another cyclically for an optimal final result of liquid transfer.

As can be seen from the list, Fluimac pumps are widely used. We could say that their diffusion is the best testimony to the quality of the product and its efficiency.

The materials used make our pumps suitable for handling liquids of all types, from alkaline to acids to food products. European and international certifications testify to their suitability for every function.

The range PHOENIX FOOD by FLUIMAC® , for example, is specially designed for the food industry. The great variety of materials also makes our pumps suitable for the most diverse uses: for example, they are resistant to corrosion and are suitable for working immersed. They are pumps capable of brilliantly withstanding contact with abrasive fluids or can be used in all phases of oil extraction and refining. But a Fluimac diaphragm pump is also synonymous with precision. The precision of flow control is as important as the ability of the materials to resist wear and corrosion. The quality of the membranes used allows not only correct movement of the liquids, but also their correct dosage.
Their pumping system, as well as the resistance of the materials, make them perfect for use even in extreme situations, in corrosive or toxic environments. The choice between Aluminium, PP, PVDF+CF and AISI 316 is perfect for use that is always suitable for the chemical and ATEX environment.

The pumping through the different chambers and the particular quality of the membranes used make them one hundred percent safe and reliable in every situation. Even in cases of transfer of viscous liquids or with solid particulates in suspension, a Fluimac diaphragm pump reacts correctly.
