Professional Chemical Grade Anti-Corrosion Hot Durable Rotor Pump
Operating Principles:
When pump lobes rotates, the space between 2 lobes increase, it will create a partial vacuum to transfer fluid into pump chamber, The pump shaft keeps turning, lobes will continue to create space to delivery fluid, the tolerance between lobes and chamber ensure the space is suitable to filled. When the pump chamber is fully filled, the fluid will be transfer to outlet.

Solution guidance
| Problem | Possible Cause | Remedy |
| Direction of Rotation | Check direction of rotation is in line with arrow on casing and nameplate |
| Air pocket in suction line | Ensure suction line filled with fluid, pipework slopes upwards, no kinks in suction line and pipework is as straight as possible. | |
| Relief Valve Failure | Clean Relief Valve. Check pressure setting. Recalibrate | |
| Check Valve Jammed | Clean check valve. Check operation | |
| Air Ingress through Seal | Check seals for air ingress, all pipework, and connected gaskets. Check pump O Rings. Replace pump seal if necessary. | |
| Relief Valve Opening or Jammed | Check relief valve settings. Recalibrate. Check and clean as a plug may have formed or solid entered jamming open. |
| Air Ingress | Check seals for air ingress, all pipework, and connected gaskets. Check pump O Rings. Replace pump seal if necessary. | |
| Low NPSH | Shorten and enlarge suction line diameter. Deepen suction pipe, increase tank contents, reduce pump speed and check fluid viscosity against pump design | |
| Pump Worn | Check internal lobe spacing. Replace lobes | |
| Check Valve Jammed | Clean check valve. Check operation | |
| Pump Cavitating | Increase pipework diameter. Reduce suction head. Check fluid viscosity. Clean filters. Reduce pump speed. Increase fluid level in tank. |
| Lobe / Rotor Damage | Check lobes and replace if necessary | |
| Misalignment | Realign Pump. Check coupling and rubber | |
| Vibration in safety valve | Increase pressure setting or replace |
Structure features
The pump cavity design is so simple. All models of pumps retain simple design styles. The fast -opening pump cover is opened to provide guarantee for user maintenance personnel without disassembling the pipeline. The driver can guarantee online repair. Greatly reduced the stop time. Before and after, the upper and lower wear -resistant internal lining design, comprehensively ensure the non -wear of the pump shell and ensure long -term durability. Such a simple maintenance characteristics reduce the operating cost of the entire life cycle of the equipment.
