The HD65 peristaltic (hose) pump from Abaque has a seal-free design that eliminates leaks and product contamination. These self-priming pumps can run in forward or reverse and offer suction lift capabilities to 25 1/2 feet, as well as the ability to run dry without adversely affecting performance, pressure and accuracy. They are available in ductile iron and stainless steel construction, allowing higher discharge pressure up to 217 psi. Pumping action is achieved by compression of a circular loop of elastomeric hose with two diametrically opposed rotating shoes. This rotational motion forces the fluid in the hose to move ahead of each shoe. When each shoe reaches the end of the loop, the reinforced hose immediately returns to its original shape, ensuring suction and priming, creating a strong vacuum pulling more fluid inside. Models are available in 13 different sizes, with flow rates ranging from .07 to 339 gpm. 215/699-8700; www.psgdover.com.
