Overview

LoadSure tubing elements

When you need a pump with positive connection points and error-free tubing loading, choose Watson-Marlow LoadSure hygienic or industrial tube elements, available for our 530, 630 and 730 series cased pumps.

 530 series pumps

LoadSure tube elements are available as high pressure up to 7 bar, medium pressure up to 4 bar and low pressure up to 2 bar. All elements use quick-release PVDF connectors which are colour coded to match the correct pumphead. Element materials include Bioprene and STA-PURE PCS for high pressure, Marprene, Bioprene, STA-PURE PCS and STA-PURE PFL for medium pressure, STA-PURE PCS, STA-PURE PFL, Pumpsil and Neoprene for low pressure.

 630 series pumps

LoadSure tube elements are available in two bore sizes of 12 mm and 17 mm and for medium pressures up to 4 bar or low pressure up to 2 bar. All hygienic elements use Tri-clamp style connectors and industrial elements use PVDF Cam & groove connectors. Element materials include Marprene, Bioprene and STA-PURE PCS for medium pressure and Marprene, Bioprene, Pumpsil, STA-PURE PFL and Neoprene for low pressure.

 730 series pumps

LoadSure tube elements are available in four bore sizes of 12.7 mm, 15.9 mm, 19.0 mm and 25.4 mm, for pressures up to 2 bar. All hygienic elements use Tri-clamp style connectors and industrial elements use PVDF Cam & groove connectors. Element materials include Marprene, Pumpsil and Neoprene.
