Self –Priming Chemical Pump
A combination of theorem and extensive experience. |
|
|
 |
The pump body is manufactured from PVDF and CFRPP, FRPP. The body and upper self-priming barrel are one piece injected without welding, for leakfree performance. |
 |
The front self priming barrel is manufactured from PVDF and CFRRP, FRPP. The flange and front self priming barrel are one piece injected without welding that greatly upgrades durability, and ensures leakfree performance. |

Poor Self Priming Barrel
 The self priming barrel can’t be sealed with pump body. An additional screw shall be fitted in the inlet port for sealing purpose.
In case of over-tightening of screw may cause glue on screw peeling off.
If screw fall into the pump, it needs to dispatch the pump and reassemble. |
|
|
 |
The conventional method is to weld the upper self priming barrel on the pump body, which may cause leakage at the welded position. |
|
 |
The conventional method is to weld the flange on the front self priming barrel, that may cause leakage and poor durability, and seal damage due to dry running.
