Pump action

摘要

A pump has, on the face of it, a straight forward job to do, but its applications are many and varied, and that leads to the need for the wide variety of sizes and styles that are available. The basic requirements for a pump are to do the job efficiently, reliably and probably with the least amount of effort on the part of the user. Some elements are shared with all equipment used on a construction site. As Per Ohstrom, vice president of marketing and business development at Godwin Pumps pointed out, emissions and fuel efficiency are going to be an issue, while improvements are being made all the time to products - for example when it comes to silent running.
