Special Rubber Expansion Joints for Water Pump Inter

1.Specification:
1)24 years manufacturing experience
2)ISO9001, ISO14001
3)Import rubber
4) China National Standards Drafting Unit of Rubber Joint
5) Qualified Joint Supplier in Nuclear Power Plant

2.Introduction:

The inner wall of the product is in form of smooth plane cylinder and lined with polyester cord fabrics. The outside protruding part is wire rope support ring. Its inner rubber is various medium resistance rubbers and outer rubber is normal rubber. The main functions are to prevent flatness under negative pressure and to endure short time inner pressure to avoid vibrating of inlet pipes bottom ends caused by pump power and suction vibrating so as to make the flow evenly raised and the pump power consumption reduced. Besides, because the inner walls of the rubber join are vertical with no fillisters (arching, or called big belly), it prevents swirls caused by the suction of the pump which improves the pumps efficiency.

3.Features:

1) This product could primarily reduce the vibration and the noise of the piping system, completely solve the different piping problems as displace of joint, axial flex and etc.
2) According to different material requirement, product could be made as acid proof, corrosion proof to suit different medium and environments.
3) The materials are good sealing, light weighting, easy to fix and maintain, also has long-working expecting. But please keep far away from sharp metal in order to avoid breaking of the rubber body.
4) For flanges of other standards or non-standards. It is necessary to be agreed upon separately. Please specify standard of furnish diagram and relative parameter. We will manufacture accordingly. Rubber material may be selected according t your requirement.
5) Anti-corrosion: EPDM and NBR rubber can bear high temperature and can anti-corrosion.
6) Double sphere flange end rubber joint: The rubber body has two bridges. It can bear more pressure and the length is long than single sphere rubber joint.
7) The size can made as customer's drawing, we can make mould for special type.
8) They are cost effective, the total cost is low because of rubber is cheap and it have long use life.

4.Our products have the following character:

Good select materials, advanced equipment, skillful workmanship, rigorous quality control standards, attractive design and durability. They are well-known for excellent quality, most competitive price, and lower cost and prompt delivery.

The product is made up of the composite rubber ball, including internal rubber layer, nylon fabric, and external rubber layer and the loose metal flange. With the merits of high pressure, stable elasticity, big displacement, good damping capacity and noise reduction, it is widely used in the systems of water supply, drainage, water circulation, heating and ventilating, and air conditioning, and the piping systems of the paper-making, the petrochemical industry, marine, compressors pumps, fans, etc
