Peristaltic Pumps
A peristaltic pump, or roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube (squeeze tube) fitted inside a circular pump casing. A rotor with a number of “rollers” (spinner) attached to the external circumference compresses the flexible tube. As the spinner turns, the part of tube under compression closes (or “occludes”) thus forcing the fluid to move through the tube. Additionally, as the tube opens to its natural state after the passing of the roller a vacuum is created and fluid is drawn into the tube.
We have introduced spring loaded spinners to our peristaltic pump product line. As the name indicates, with the spring loaded spinners the rollers are mounted on a spring. This innovative design helps overcome the variations in the tube wall thickness as the tube deteriorates over time. Irrespective of tube wall thickness and elasticity, the roller imparts the same amount of stress on the tubing resulting in dosing accuracy and consistency throughout the life of the squeeze tube.

Volumetric Injectors
Our volumetric liquid chemical injectors are powered by water-flow, making them the most environmentally friendly injectors on the market!
Our unique design begins with the water-powered “motor”. The motor utilizes a reliable and durable diaphragm assembly, which is activated by the flow of water through the body of the injector. The higher the flow of water through the injector, the faster the diaphragm moves. The diaphragm assembly moves in direct relation to the water flow which is one of the reasons our injectors are known for their unparalleled accuracy.
The next element of our unique design is the chemical pump assembly. The positive-displacement pump dispenses a precise amount of chemical solution. Chemicals are injected into the water after it has passed through the water motor, eliminating the potential for chemical deterioration of the water motor. The action of the chemical pump and resultant volume of injection is controlled by the diaphragm assembly. This ensures the right amount of chemical is injected into the water. Never more, never less!
