High Efficiency Daily Chemical Additive Transfer Stainless Lobe Pump
Product Overview
Accuvon Rubber Rotary Lobe pump are super self-priming. This positive displacement is similar to a gear pump, but the lobes don't touch each other and turn independently. Lobe pumps are utilized for transfer liquid of various viscosity and air/water mixture.
The feature a robust design (in between bearing support), that enable operation operation at high pressure and low vibration.
Intermediate isolation chamber, ensure the gearbox are isolated from medium, even if there a leak.
Built-in gear reducer is optional, for space saving.
Material: Cast iron/Cast steel/Stainless steel and various polymer.

Solution guidance
| Problem | Possible Cause | Remedy |
|
Motor Operational but No Fluid Delivery | 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. | |
|
Insufficient Capacity | 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 Noisy | 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:
The whole body uses the stainless steel materials, equipping with common or anti-explosion electric motor. It's suitable for conveying liquid materials in various places and makes sure the production procedure in accordance with GMP quality standard.
