Gaodetec peristaltic metering pumps have a special rubber hose with smooth inner walls and high strength. The rubber hose is squeezed and squeezed by a pair of pressure rollers to flatten the hose. This rotation allows the media to be transported in one direction without backflow. After the hose is transferred, the hose returns to its original state under the force of the flat hose and the force of the side guide rollers. At this time, a high vacuum is created in the hose to draw the medium into the inner cavity again. The medium is then discharged from the tube under a subsequent pressure roller press. Reciprocating, the medium is continuously sucked in and discharged. It has special valveless low-speed and low-pressure transportation characteristics, which will not cause substantial changes to the slurry. It is especially suitable for some slurry transportation with expansion, air bubbles, fibers, foam and other characteristics.

Gaodetec peristaltic metering pump is specially designed for water and wastewater treatment. It is a high-toughness-shaped tube specially designed for squeeze hose pumps. It can meet full shape recovery and wear resistance. The extruded hose is mainly divided into high elastic and wear-resistant outer layer, compressive interweaving combined with middle layer and tough and smooth inner layer. The materials are fine, the processing is fine, the process is special, and different materials are adjusted to produce different applications.

During the whole working process of peristaltic metering pump, only the hose can contact the medium. The peristaltic metering pump restricts the medium in the pipeline, so that the pump cannot contact the fluid, and the fluid cannot contact the pump. The unique sanitary design, Prevent cross-contamination. This pollution-free pumping makes food-grade peristaltic pumps particularly suitable for high-purity applications, including the transfer or metering of chemicals and additives in water and wastewater treatment, food, beverage, pharmaceutical, and semiconductor applications.

Chemicals and reagents pumped by peristaltic metering pumps include ferric chloride ("ferrous"), sodium hypochlorite ("hypochlorite"), chlorine water, lime (Kalic® or Kalkmilch), sodium hydroxide, powdered activated carbon and Polymer, and other crystalline objects, effectively prevent the hose from being blocked.

Peristaltic metering pumps are often used for precise chemical dosing in water and wastewater treatment and can be repeatedly fed with a variety of different chemicals, while handling the following liquid problems:

1. Lime has a grinding effect and can cause the diaphragm pump to become blocked. The viscosity of lime can cause wear on the screw pump.

2. High wave exhaust gas caused by metering pump air resistance during pumping caused untreated liquid to flow.

3. Polymers are often sensitive to shear stress, and screw pumps reduce particle size leading to increased chemical use.

4. Mud often has a high content of coarse sand, which will cause mechanical wear. Many pumps, including rotary pumps, will encounter the problem of heavy-granular layering when handling primary sediment.

Peristaltic metering pumps can also be used for long-distance viscous slurry transportation in construction, underground engineering, mining, food, papermaking, ceramics and other fields, metering pumping, pressure grouting, spraying, etc.
