vertical vs horizontal raw marine sewage transfer pump
6PNL-35 marine sewage transfer pump:patent product,abrasion resistant material,advanced structure design,widely used in desilting,sand pumping,slurry discharge,etc,main parts function as following:
marine sewage transfer pump features: |
1.Single stage and single suction |
2.haft open impeller |
3.anti abrasive material,high chrome alloy(flow parts) |
4.Adjustable between impeller and protection plate |
5.Max density:50-60%(by weight) |
6.easy intallation |
7.Efficient working |
1. 90°winding outlet ,connect with pump casing by 8 bolts,can be changed to different directions according to need.
2. Pump casing:connect with support frame by 6 bolts,abrasion resistant impeller is installed inside,outlet direction can be adjusted as per 60°gap.
3. Protecting plate:made by high chrome alloy,installed between pump casing and support frame,fixed by 6 pieces bolts on pump casing and support frame.
4. Oil fitting:for bearing box oil injection,screw tightly after injecting 2kg oil.
5. Shaft seal box:installed outside of protecting plate,there are seal parts inside,easy installation and maintainence.
6. Oil fitting:installed on shaft seal box,convenient to lucbricate the seal parts in order to prolong the seal parts and shaft sleeve lifetime.
7. Shaft sleeve:made of high chrome alloy,installed on pump shaft between round nut and impeller for protecting the shaft because of its abrasion resistant material.
8. Round nut:left-hand thread,two pieces every pump,can fix and lock the impeller after adjusting the impeller gap properly,please loose the round nuts first when dismantle impeller.
9. Water retaining plate(oil seal type pump):installed on pump shaft and next to bearing gland,rotate with pump shaft in same speed and direction.if mechanical seal pump,the machanical seal gland is same as 6PNL-35 in design.
10. Support frame:installed between pump casing and bearing box,it is main part for supporting pump casing and bearing box.
11. Pump rotation direction is clockwise judge from motor side,counter clockwise is prohibited.
