This invention is directed to a fluid pump containing a structural member, such as a casing, which the fluid contacts as it enters the pump, and to a structural member having sufficient mechanical strength and flexibility for use in a fluid pump, such as a casing, which is made of a ring-opened polymer of a norbornene-type monomer containing an effective amount of an elastomer, the structural member has heat distortion temperature of over 120°C, elongation at break of 15 to 80%, and flexural modulus of elasticity of 170 kg/mm2 or above.
Cette invention concerne une pompe dont le corps présente une résistance mécanique et un souplesse appropriées à l'usage et qui est fait d'un polymère à chaîne ouverte d'un monomère de type norbornène renfermant une quantité appropriée d'un élastomère. Le corps de pompe se caractérise par un point de déformation à chaud de plus de 120 degrés Celsius, un allongement à la rupture de 15 à 80 % et un module d'élasticité en flexion de 170 kg/mm2 ou plus.
