Floor screeding pumps operate at high pressures to move screed along their connected pipes. The energy of the high pressure can cause the pipes to move, shake, scrape and bang into objects near them.

Typically the pipes are joined by metal clasps and you certainly would not want these clasps whacking into anything delicate.
