EXAMPLE STATOR MATERIALS PROPERTIES:

• Natural Rubber (NR): Products that are resistant to abrasion. They offer good resistance to diluted acids, detergents, and alcohols. However, they are not suitable for prolonged exposure to solvents, greases, or hydrocarbon oils. Temperature range: -30°C to +80°C
• Nitrile (NBR): Exhibits excellent resistance to greases, oils, and certain hydrocarbons (like gas oils). It also withstands wastewater and abrasive materials. Temperature range: -25°C to +100°C.
• Ethylene-Propylene (EPDM): Offers exceptional resistance to weather conditions, ozone, sunlight, and air. It also provides high chemical resistance to acids, alkalis, detergents, alcohols, ketones, and bleaching agents. Temperature range: -30°C to +110°C.
• Viton (FPM): Designed for high temperatures (up to 250°C at the tips). It performs well in hot oils, acids, alkalis, and has excellent resistance to petroleum by-products, aliphatic and aromatic solvents, as well as chlorine. However, it is not suitable for aldehydes, esters, and ketones. Temperature range: -25°C to +250°C.

WE MUST CONSIDER THE PUMP WORKING CODNITIONS AND THE PUMPING FLUID WHEN CHOOSING RIGHT MATERIAL.

PURPOSE OF PUMPING CAN CHANGE DURING PUMP LIFETIME WHICH COULD CAUSE DIFFERENT MATERIALS NEEDS.

TO ALLOW US QUOTE SUITABLE SPARES PLEASE SHARE FULL PUMP TYPE AND IF POSSIBLE - TYPE OF FLUID WITH PUMPING TEMPERATURE. IF YOU ARE SURE ABOUT USED SOLUTION PLEASE JUST SPECIFY NEEDED MATERIAL.

DUE TO VERY DIFFERENT ENVIROMENTS AND PUMPING FLUIDS IT’S VERY IMPORTANT TO SELECT PROPER MATERIAL OF SPARES
