Abstract Impeller stress for pumps made of engineering plastics was analysed.The coefficients of k1 for various ns were summarized.The strength calculating formula for the impeller was obtained based on simplified model and cover board theory.The strength of pump impeller made of engineering plastics in common use was proofreaded by using this formula.The results show that UHMWPE and PP can be used in limited field and PPO and PVDF are the best,which provide the theory for engineering plastics choice.impeller;engineering plastics;strength;stress
