Advantages of Vector Pumps Once you've decided that a peristaltic pump is the right type of pump for your application, how do you make a decision as to which type to purchase? Important factors to consider include pricing (value), service, delivery and design.

Pump Design is Important !
With peristaltic pumps everything boils down to hose life. Peristaltic pumps are constantly compressing the hose - the ability of the hose to regain its' natural shape after compression creates the pumping action. As the hose is constantly compressed and uncompressed fatigue takes place and it doesn't quite regain its' full shape after compression. Eventually the edges of the hoses split and pumping action ceases.
Vector Pumps compress the hose with a set of rollers. As the hose is compressed the rollers are rolling along the surface of the hose, minimizing friction. Our competitors use what is referred to as a "shoe" design. A fixed rounded shape moves around on a wheel, compressing the hose as it rotates. This design applies more friction to the surface of the hose so it is being worn by both compression and friction.
Vector Pumps require a light coating of lubricant on the hose to minimize friction further. Our competitors often submerge their hoses in a lubricating bath. The lubricating bath complicates hose changes and is a source of potential contamination.
The following two pictures illustrate the fundamental difference between the patented design of Vector Peristaltic pumps and other types of peristaltic pumps.
VECTOR PUMP | "Competition" |
| VECTOR: Roller design coupled with its' patented hose guide causes less stress and wear on hose, extending hose life. |
 |
The "competition" incorporates a "shoe" design which causes more stress on the hose (shorter hose life) and often requires a lubricating fluid to help hoses last longer. |
| The Vector Pump housing incorporates a patented "hose guide", which serves the purpose of controlling the compression of the hose. By controlling the amount of compression hose life is extended. Wanner Engineering also supplies special hoses that are designed specifically for use in Vector Pumps. Some hoses are extruded and others are fiber braided (to increase strength), but all are designed to withstand compression better than ordinary hose you purchase from an industrial supply company. The last key factor to extending hose life is the RPM at which the hose is compressed. Generally speaking, the lower the RPM's and frequency of compression, the longer you can expect the hose to last. We try to size Vector Pumps so that you can expect from 1000 to 2000 hours of operation for each hose. There are other factors that affect hose life so we usually discuss hose life on a case-by-case basis. |
Don't Forget Delivery, Service and Value !
DELIVERY. Wanner Engineering and their pump distributors usually have pumps and hoses available to ship from stock. Gear motors are usually available within a week so it is realistic to expect shipment of your pump system within a couple of weeks after you place you order.
SERVICE. The ability to obtain answers to your questions, expedite shipments and provide the right pump for the application is very important. Wanner Engineering markets their products through sales representatives like TPS that specialize in fluid handling products. Our network of industrial pump distributors keeps finished product scattered throughout the territory we serve.
VALUE. Tie everything together - Design, Delivery, Service - and it helps you determine the value of that product. Wanner Engineering's Vector Pumps maximize the value for your dollar.
