Industrial grade peristaltic pumps, aka “hose pumps”, are a type of sealless positive displacement pump having excellent suction lift and excelling at pumping difficult to pump liquids. Due to their simplistic design consisting of a hose which is compressed, they are often used to transfer viscous liquids and liquids containing a high percentage of solids, which includes waste water, chemical slurries and food processing applications.

Depending upon the specific pump model, the only maintenance required for this type of pump are replacement hoses and hose lubrication. The hoses which are used in industrial grade peristaltic pumps are typically designed to last >1500 hours of usage. Most peristaltic pump brands offer their hoses in similar materials and functionally they all operate on a similar principle. Following is a brief summary of the 6 most common industrial peristaltic pump brands in alphabetical order with a universal cross reference chart for ordering replacement hoses.

 

Pump Design Comparisons
All brands have a similar flow rate and pressure range with some of the highest capacity pumps having multiple pump heads mounted to a single gear motor.

There are two primary hose compression designs, using a “shoe” and using “rollers”. The shoe design contains two or more rounded profiles which pinch a section of the hose as they are rotated. The external area where compression occurs is filled with a lubricant to reduce the friction of the shoe as it slides against and compresses the hose. A roller design typically requires only a light grease lubrication on the external surface of the hose because the rolling nature of compression results in less friction. Roller designs are limited to <100 PSIG discharge pressures whereas shoe designs are limited to <232 PSIG. The exception is with the Hau Yun design which uses a hybrid “lubricated roller” design, so it has the lubrication of a shoe design using a roller method for compression and thus can operate at pressures <232 PSIG and the hoses tend to last longer due to less shear against the hose surface and they also happen to utilize a thicker walled hose.

The following hose size comparison chart enables you to cross-reference the dimensions of your hose to hoses used for other manufacturers and it is not coincidence that most of the hose dimensions are the same; this is because there are only a few actual “hose manufacturers” and thus most peristaltic hose pump manufacturers are procuring their hoses from the same few vendors. Notice that while the ID is identical, the OD (in most cases) only varies by 1 mm and it is primarily the length which varies the most. Thus, we represent the Vector and Hua Yun brands which enables us to supply replacement hoses for all the major brands of peristaltic pumps, trimming the hoses as needed.

If you are going to obtain your replacement hose from a distributor of another brand, be sure to measure your hose ID, OD and length as confirmation; especially the hose ID because in the USA the fittings adapted to the metric sized hoses may vary, so just because you have a 1½” connection doesn’t mean you have a 38mm hose ID, a 1½” connection is commonly adapted to 32mm and 40mm ID hoses. Length is important also, it is acceptable to trim a longer hose, but there is no way to properly “extend” a short hose.
