Further to my conversation with your colleague this afternoon, I wish to confirm (that) our order for five hydraulic pumps (ref SG 94321) will arrive no later that March 21. Please let us know about about any problems processing this order. We are especially concerned about receiving the parts on time, as it is for an important customer.
