WILDEN Diaphragm Pump Accessories 01-1060-51 Neoprene Backing Diaphragm for WILDEN P1

Neoprene (CR) diaphragms, due to their unique molecular structure (containing chlorine atoms), exhibit excellent comprehensive performance in a variety of industrial scenarios. Their core characteristics and advantages mainly include the following aspects:

Core features

1. It has strong resistance to ozone, ultraviolet rays, oxygen and temperature changes. It is not prone to cracking, hardening or elasticity loss when exposed to outdoor environments for a long time. It can maintain stable performance in the temperature range of -30℃~120℃.

2. It has good tolerance to dilute acids (such as hydrochloric acid and sulfuric acid with a concentration of ≤10%), dilute alkalis (such as sodium hydroxide with a concentration of ≤15%), salt solutions and most polar organic solvents (such as ethanol and acetone). It also has outstanding water resistance and low water absorption (<1%), making it suitable for contact with aqueous or weakly corrosive media.

3. The tensile strength reaches 18~25MPa, the tear strength is ≥35kN/m, and it has strong fatigue resistance. It is not easy to crack or break under high-frequency reciprocating motion (such as the working state of a diaphragm pump). It has good adhesion to pump body materials such as metal and plastic to avoid delamination and leakage.

Outstanding advantages

1. It can alternately transport a variety of media such as dilute acid, dilute alkali, water, low-concentration solvents, etc., without the need to frequently replace diaphragms, thereby improving the versatility of the equipment and reducing downtime for component replacement.

2. Under normal working conditions, the service life can reach 3000~5000 hours, which is 2~3 times that of ordinary rubber diaphragms, and can effectively reduce operation and maintenance costs.

In summary, the balanced performance of chloroprene rubber diaphragms in weather resistance, chemical compatibility, safety, and durability makes them an ideal choice for outdoor operations, transportation of weakly corrosive media, and safety-first scenarios.
