US company Aalborg has developed the new model TPU tube pumps for liquids of low to medium viscosity.

Aalborg says that chemically resistant tubing materials and new peristaltic pump head technology combine to meet the demands for reliable, long-term pump operation. Aalborg adds that four stainless steel rollers (an eight roller option is also available) minimise pulsation and promote longer tube life.

According to the company, the TPU’s tube set-up, changes, and replacements are quick and easy. Tubing inside diameters offered are 1/8 inch (3.2 mm), 3/16 inch (4.8 mm), ¼ inch (6.4 mm), or 5/16 inch (7.9 mm), each with a 1/16 inch (1.6 mm) wall thickness The size and material of the tubing chosen, as well as the selected fixed RPMs of the motor drive, determine the flow rate. Pumped fluid never touches the pump.

Aalborg explains that this economical model delivers smooth, precise operation and virtually eliminates maintenance problems. The pump design features include sturdy occlusion wall and back plate, as well as self-priming and a compact, small foot print design. The new tube pump is mountable in any direction, can operate using a 115 volt or 230 volt service, and has fixed RPM AC gear motors.

Industry-specific applications include: science and research; OEM; processing; engineering; agriculture; analytical chemistry; pharmaceutical production; sewage sludge; paint and pigments; pulp and paper; food manufacturing; beverage dispensing; and carbon monoxide monitors.
