High-pressure water jet cleaning equipmetit driven by compressed air has been introduced by Morrison Pumps for use where conventional methods of drive could prove hazardous. The standard design Morrison pump is fitted with a compressed air motor with water trap and oil-mist lubrication.
The air motor requires air at 551kN/ sqm (80psi) at a rate of 77 cu m per min (250 cu ft per.min) to produce a pressure of 10.342kN/ sqm (1500psi). Altering the volume of compressed air varies the water jet pressure.
The machine uses cold water from a portable tank or any other source and can be fitted with various attachments to suit different jobs.
