Explosive Industry Pumps

Explosive Industry Pumps In India Safety in mining and at construction sites where explosives are used was a problem for a long time, because the storage and transport of “volatile” explosives always constitute an enormous risk. In order to reduce the danger and achieve a better explosive performance, there has for some time been greater use of pumpable emulsion explosives.

A global explosives manufacturer had used a progressing cavity pump to fill the storage silos with the ready-to-use ammonium nitrate emulsion. However, the pump did not provide the required level of performance and delayed the supplying of the mines and customers due to regular breakdowns. The pin joint could not withstand the torque nor the deflection on the coupling rod and therefore often failed. The shortness of the coupling rod increased the angle which the joint had to compensate. That not only increased the stress on the joint itself, but also the dynamic load on its seal system. The lubricating effect of the lubricant used for the pin joint was not sufficient either. As a result, the pump was constantly breaking down. Since the pump had a crucial role to play in the process chain, every breakdown led to costly delivery delays.
