WebHigh-Pressure Air-Powered Drum Pumps for Chemicals. With a higher pressure than other air-powered drum pumps, these pumps move thick chemicals with a viscosity of up to 5, … WebHigh back pressure in LC instruments is usually caused by foreign material blocking the flow of mobile phase. Although crimped PEEK or stainless steel tubing will occasionally be the culprit, particulates clogging the system are most often the cause. Note that PEEK tubing is incompatible with tetrahydrofuran and will swell if exposed to it, so ...
