Industrial Hose Pump Selection Guide Operational Overview and Ordering Information Principles of Operation Hose pumps are self-priming rotary positive displacement pumps that operate on the peristaltic principle. The pump consists of three major parts: hose, housing and rotor. The hose is placed in the tubing bedbetween the rotor and the housingwhere it is occluded (squeezed). The rollers or shoes on the rotor move across the hose, pushing the fluid. The tubing behind the shoe or roller recovers its shape, creating a vacuum and drawing fluid in behind it. A pillow of fluid is formed between the rollers specific to the ID of the hose and the geometry of the rotor. Flow rate is determined by multiplying speed (rpm) by the volume of the pillow. This pillow volume is consistent, even under a wide range of viscosities. Note: Before you order an Industrial Hose Pump you must fill out an Industrial Pump Specification Sheet.

| | Dry-running pump design | This design incorporates a unique tube bed that always ensures one roller is occluding the hose. Termed dry-running because rollers that do not operate in a lubricated bath occlude the hose. Dry running pumps are available in models capable of discharge pressures up to 60 psig (4 bar), producing flow rates up to 108 GPM (24.5 m3/hr). | | Lubricated-bath pump design | This design uses two sliding shoes on the rotor to occlude the hose. The rotor and hose operate in a lubricated bath that reduces friction on the hose and provides the long life typical of this type of hose pump design. These pumps are capable of operating at discharge pressures up to 220 psig (15 bar), producing flow rates up to 68 GPM (15.5 m3/hr). Each pump is shipped with a belt-driven mechanical variable-speed drive that provides a minimum 5-to-1 turndown on the maximum rated output speed. The motors have TEFC (IP54) enclosures, Class F insulation, and are coupled to a gear reducer with a minimum AGMA Class II rating (1.4 service factor). Motors are UL-listed and CE-approved and meet the EPACT 92 standard for motor efficiency ratings. All pumps are shipped assembled, pre-aligned on a steel base plate with flexible coupling and OSHA-rated coupling guard. Each pump is provided with 1 set of standard hose barb connectors, 1 hose (two hoses with dual-head pumps), and 250 g of grease (lubricated pumps include one glycerin fill for the pump housing). We offer a number of custom drives not shown in the IP Pump section, including mechanical varispeed, inverter variable drives, hazardous area rated drives, wash-down, chemical duty, and air operated drives. Optional inlet and outlet connections available include ANSI 150# flanges, sanitary Tri-clamp® fittings, and NPT connections. |
