neutral compound
1.The wet parts of this pump are made of full stainless steel material to perform outstanding corrosion resistance to organic acid， organic compound， alkali， neutral solution and a great many of gases， double helix carbon graphite bearing and hardalloy bearing are provided with good abrasion-resisting propertyto ensure the service life of product， it is an optimal pump forhandling corrosive mediums without leakage.
2.In allusion to welding pool of aluminum alloy, the compound filter system which is composed by a 1064nm central wave length narrowband filter and a 0. 1% neutral filters is adopted. Clear welding pool images like taper are collectted. The welding pool of aluminum alloy is mostly covered with blazing arc.
