Concrete Pump Snap Clamp Coupling
About concrete pump snap clamp coupling, we have forged coupling and casting coupling. Our galvanised snap coupling with safety pins , this kind of clamp coupling is usually used on Austraulian customers.In the formal situation, 2"-3' snap coupling type is usually different from 4"-8" clamp coupling, we can show you on the below piuctures :
(2).Type: Galvanised Quick(snap), Wedge, Adjustable, Raised lever, 1/2/4 bolt mounting, HD adjust clips.
(3).Brand: Zoomlion, Sany, Schwing, Kyokuto, Hainuo, Xugong, PM, CIFA ETC.
(4).Working pressure: Forged clamp(Galvanised coupling) is 130bar, cast clamp is 85bar .
(5).Cast pressure: Forged clamp(Galvanised coupling) is 200bar, cast clamp is 125bar.
(6).Collar:SK/FM/ZX/HD flange .
(7).Material: 40Cr, after 1050°C heating anf forging, then it is shaped.
Also we have the Ameircan specialized HD adjustable clamp coupling, working pressure is 180bar, burst pressure is at least 200bar. If we thickning the clamp coupling, quality is better, working pressre is 350bar, burst pressure is 600bar, each one weight is heavier, this kind of clamp coupling is usually used in Germany Schwing .
