Gasket Diaphragm Rubber

Gasket Diaphragm Rubber is used in applications where nuts are required for fastening. It is suitable for use in pressure-bearing applications and can be reinforced with fabric layers, starting from one layer, depending on the pressure.

Why Use a Diaphragm Rubber?

First, it’s important to understand the diaphragm pump. A diaphragm pump is designed to pump fluids that are highly acidic or alkaline, viscous liquids, or liquids containing sediments. The pump transmits power through a diaphragm rubber sheet, which separates the machinery side from the fluid side to prevent direct contact of the liquid with critical pump components.

The diaphragm pump consists of:

  1. Diaphragm Rubber: Typically, there are two types:
    • Single Diaphragm Rubber
    • Double Diaphragm Rubber, which alternates pushing back and forth with air pressure. One side of the diaphragm is pulled into the center, causing the fluid to be drawn into the pump, while the other side is pushed out, expelling the fluid through the outlet pipe.
  2. Check Valve: Creates pressure.
  3. Plunger: Transfers power from the motor and gear set.
  4. Air Release Valve: Releases air from the fluid chamber.
  5. Replenishing Valve: Releases some pressure to prevent the diaphragm from becoming damaged due to excessive workload.
  6. Pressure Limiting Valve: Adjusts the pump’s pressure settings for appropriate use.

The diaphragm rubber is a crucial component of the diaphragm pump and can become damaged with continuous and excessive use. Therefore, it is important to choose the type of rubber diaphragm that matches the application, including its shape and characteristics, such as reinforcing fabric to enhance strength and durability or using Teflon diaphragms for resistance to concentrated solvents.
