Rubber Diaphragms

Diaphragms are one of the most commonly used sealing components across all industries. Rubber diaphragms provide a perfect seal between different chambers, offering leaf-proof and air-tight protection. With the ability to withstand extreme temperature and pressure changes, Arvico’s diaphragms are long-lasting too. 

Diaphragm designs vary for different pumps and valves, and we understand this best. Our diaphragms components can be customized in various grades of rubber and the sizes preferred, thanks to our in-house die-casting unit. Our diaphragms match 100% customer requirements and are used in many industries to control the flow of fluids precisely.

Rubber diaphragms are an essential component of various pumps and valves, providing durability, reliability and precision. Whether you’re looking to replace existing parts, or you’re searching for diaphragms for a new installation, you want to make sure that you’re getting the best quality for your investment.

we’ll explore everything you need to know about rubber diaphragms, including different types of diaphragms, their applications, and why you should order from a Arvicorubber.

What is Rubber Diaphragms?

A rubber diaphragm is a flexible and elastic membrane that separates two fluid-containing spaces. They are used in various industrial applications as an actuating element in pumps and valves, working to regulate and control fluid flow.

Rubber Diaphragms Pump

Diaphragms pumps use a flexible membrane to separate the fluid being pumped from the pump mechanism. The movement of the membrane creates suction, which draws fluid into the pump, and then the release of the membrane creates pressure, which pushes the fluid out of the pump.

Types of Rubber Diaphragms Pump

There are several types of diaphragms pumps, including AODD diaphragms, impellers, and PTFE diaphragms. Each type has unique features and benefits that make it suitable for different applications.

AODD diaphragms

AODD diaphragms are made from a range of materials, including nylon, polyurethane, and silicone, and are often used in high-pressure pumping applications.


Impellers are a type of diaphragm pump that uses a rotating mechanism to move fluid. They are typically used in high-volume applications and are known for their efficiency and durability.

PTFE diaphragms 

PTFE diaphragms are made from a type of plastic and are commonly used in applications that require chemical resistance. They are also resistant to heat, making them ideal for use in high-temperature applications.

Rubber Diaphragms Valve

Diaphragms valves use a flexible membrane to separate the fluid being controlled from the valve mechanism. When the valve is actuated, the movement of the diaphragm regulates fluid flow through the valve.

Types of Rubber Diaphragms Valve

There are several types of diaphragms valves, including PRV diaphragms, control valve actuators diaphragms, straight through KB type diaphragms, metal-bonded control valve diaphragms, rubber pads, spare diaphragms, and valve diaphragms.

PRV diaphragms

PRV diaphragms are used in pressure relief valves and are designed to release pressure in the event of an overpressure situation.

Control valve actuators diaphragms

Control valve actuators diaphragms are used to control the flow of fluid through a valve. They are typically used in applications where precise control of fluid flow is required.

Straight through KB type diaphragms

Straight through KB type diaphragms are used in applications where fluid must pass through the valve in a straight line. They are often used in piping systems where space is limited.

Metal-bonded control valve diaphragms

Metal-bonded control valve diaphragms are made from a range of materials, including stainless steel and brass, and are used in applications that require high durability.

Rubber pads

Rubber pads are a type of diaphragms that are used to control fluid flow in industrial applications.

Spare diaphragms

Spare diaphragms are diaphragms that can be replaced when they become worn or damaged.

Valve diaphragms

Valve diaphragms are used to control fluid flow in valves, helping to maintain the pressure and flow rate of fluids in a system.

In conclusion, rubber diaphragms play a critical role in a wide range of industrial applications, from pumps and valves to mechanical systems. Whether you need diaphragms pumps, valves, or spare parts, be sure to order high-quality rubber diaphragms from a reputable supplier today!
