Rubber Impeller

Patent Rubber Impeller Sea Water Pump for Diesel Engine
Optimized Rubber Solution for Marine Client

Type JLB8073 rubber impeller sea water pump have got the certificate of China Marine Classification Society (CCS).JULONG RUBBER IMPELLER can maintain 2000 hours continuous working in the muddy sea water without leakage water with 2100 R/min rotate speed，resistant to the billion times tensil trength test,suppling to Shanghai Diesel Engine Company Limited as an exclusive supplier.This is the classic case of our company to deliver the most optimized solution.

The characteristics of rubber impeller

1.Hardness Shore A:75±5
2.Apprearance: No defect
3.Color:black
4.Tensile strength≥20MPa
5.Elongation strength≥250%
6.Tearing permanent deformation:≤6%
7.Rubber elasticity:≥25%
8.Akron:≤0.5cm3
9.Flex cracking:≥10000000times
10.Peel strength requirements: rubber rupture      

The test of simulates flexible impeller damage  

The test plate of rubber impeller sea water pump and user testing shows that:both domestic and imported rubber impeller sea water pump,if the damage occurred,it is mainly because of the flexible impeller blades to fatigue crack or split.As this sea water pump with twelve blades,if few piece of blades split,though the flow will be reduced in varying degrees,the pump still can continue to work.

Damage leaves,the reduction of flow to what extent? We will cut off the blades piece after piece(to simulate the blades damage),and test the flow,the result are as the followings:

Speedr/min	Life head MPa	Standard flow L/min	Test flow L/min	Compare to standard flow	Cut off 1 blade			Cut off 2 blades			Cut off 3 blades			Cut off 4 blades			Cut off 5 blades			Cut off 6 blades
					Flow L/min		Compare to standard flow	flow L/min		Compare to standard flow	Flow L/min		Compare to standard flow	flow L/min		Compare to standard flow	Flow L/min		Compare to standard flow	Flow L/min		Compare to standard flow
