A question for the pump experts on the forum; the line of horizontal split-case fire pumps I'm familiar with generally come as 1770 RPM or 3560 RPM.
What is the benefit to using one versus the other? Do contractors generally have a preference? Is cost, sounds, wear-and-tear impacted by the RPM selection? Thanks in advance.

From a high level guess...

Another benefit is that, generally low RPM pumps' NPSHr is less than high RPM pumps. Which is important if you may experiance high pressure drops on your suction line.

low rpm is preferred if less noise due to vibration is required
