Peristaltic pumps (also known as hose pumps, tube pumps) are a type of positive displacement pump which are widely used in water treatment, chemical processing and food processing industries. It creates a steady flow for dosing and blending and is able to pump a variety of fluids, ranging from toothpaste to all sorts of chemicals.
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 tube immediately returns to its original shape, thereby ensuring suction and priming.
The pump housing is partially filled with lubricant, aiding smooth running of the shoes on the hose. The inside of the hose and hose inserts are the only pieces of equipment in contact with pumped fluids, allowing aggressive and contaminated fluids to be pumped.
ST Peristaltic Hose Pump Overview
The Abaque Series peristaltic hose pumps can handle your toughest pumping needs – from abrasive and aggressive fluids to shear sensitive and viscous materials, while a seal-free design eliminates leaks and contamination. The advanced design and solid construction reduces maintenance and repair requirements, with the hose as the primary maintenance component.
The Abaque hose pump is self-priming to 9 meters (25.5 ft) manometric lift with discharge pressures of 16 bar (232 psi). It is capable of running in forward or reverse, and can run dry continuously without any detrimental effects. All Pumps has been importing, servicing and supplying Abaque Series pumps in Australia for 7 years and supports the full Abaque peristaltic range of pumps and spare parts.
Graco SoloTech (ST) series offers one of the most advanced technologies seen in peristaltic hose pumps.
Graco’s positive displacement hose pumps rotate a full 360-degrees. Because they use a single roller to compress the hose once per revolution, your hoses last longer so you have less maintenance and downtime.
