30 sets of DPSB type stuffing boxes ordered by our customer have been finished production after 30 days of producing, which are expected to be delivered to customer this week. This batch of stuffing boxes is additional part of the order after they ordered a small batch of our products with good performance. Despite of the tight production time, but we overcame all the difficulties and delivered on time, meanwhile ensuring that the product quality is in full compliance with API standards. And keep the quality of the products completely same with that in the past.
