Why it is important to understand and to know the manufacture process of stators?
In each area of application has specific demands, as far as the resistance of the rubber exist. Our decades of experience allows us to adapt the mixture of rubber to the demands of each client.
Advice of use
At the moment of change of stator as well as after a shut down of production it is convenient to make sure that from the first turnings it pumps product, because if a clogging has taken place, the stator can be quickly damaged.
Materials used for manufacturing stators:
Close materials
Natural rubber (NR)
Products to basically resist abrasion. Good resistance against diluted acids, detergents and alcohols. It is not appropriate for applications that shall come in prolonged contact with solvents, greases and hydrocarbonic oils, which cause it to swell significantly. Temperature range -30°C +80°C
Nitrile (NBR)
Excellent resistance against greases and oils, as well as some hydrocarbons (gas oils). Waste water and abrasive products. Temperature range -25°C +100°C
Ethylene-Propylene (EPDM)
Excellent resistance against weathering, ozone, sunlight and air. High chemical resistance against acids, alkalis, detergents, alcohols, ketones, washing bleaches, etc. Temperature range -30°C +110°C
Viton (FPM)
High temperatures (up to 250ºC on tips). Hot oils, acids, alkalis. Excellent resistance against by-products of petroleum, aliphatic solvents, aromatic solvents and chlorine. Diluted acids, detergents and oxidising acids. Not appropriate of aldehydes, esters and ketones. Temperature range -25°C +250°C
Neoprene (CR)
Excellent resistance against ozone, sun and weathering. High resistance against acids, alkalis and their by-products. It is flameproof Temperature range -25°C +110°C
Hypalon (CSM)
Excellent resistance against strong acids and oxidising agents, against weathering and ozone. High resistance against oils and heat. Temperature range -25°C +130°C
