Product details
1、 Product Introduction and Working Principle
The RGB series hose pump (also known as peristaltic pump) works by squeezing the hose with rollers or sliders. Pumps can operate dry, self suction, and handle high viscosity and high wear media. The pump body does not need to be sealed, is completely leak free, and can output a fixed flow rate with each rotation. It has the characteristics of low speed and no noise, and is widely used in metallurgy, rare earth, desulfurization and environmental protection, water treatment, papermaking, painting, titanium dioxide, compound fertilizer and other industries. This series of pumps comes in two forms: single tube and double tube.
1.1 Working principle
The working principle is shown in Figure 1, which consists of components such as hose 1, roller 2 mounted on rotor 3, and pump casing 4. When the rotor is rotated, the inner cavity A of the hose formed by the squeezing of the roller and the pump housing gradually increases from generation, and this cavity is in a suction state. When the rotor rotates to position b in Figure, the liquid that has entered chamber A is pushed by the roller to the enclosed cavity B. When it reaches position c in Figure, this part of the liquid is pushed back to chamber D, which is connected to the pump outlet, and then discharged outside the pump. The continuous rotation of the rotor forms a continuous "creep" of the hose, which continuously transports the liquid from the low-pressure inlet of the pump to the high-pressure outlet.
The number of rollers for squeezing the hose with a peristaltic pump can also be two, three, or more. On some pumps, the rollers are replaced by low friction compression elements with special front and rear edge shapes. Figure 2 is a schematic diagram of a peristaltic pump structure using two pulleys instead of rollers.
1.2 Main characteristics of the pump
a. Strong self-priming ability, with a water suction range of up to 8m;
b. Unique structure, no sealing is used, so there will be no leakage;
c. Can transport corrosive slurries, sludge, etc. containing a large amount of particles, fibers, or other impurities;
d. Low medium flow rate and no shear force, especially suitable for conveying materials sensitive to shear force;
e. Can transport high viscosity media, as well as three-phase mixed media of gas, liquid, and solid;
f. By adjusting the speed of the pump, the flow rate can be adjusted while the outlet pressure of the pump remains basically unchanged;
g. When the speed is constant, adjusting the outlet valve can change the outlet pressure of the pump, while the flow rate remains basically unchanged. Therefore, this pump has a certain metering function and can be used as a metering pump;
h. By using different hose materials, it can be adapted to different media. (Please request the corrosion parameter table of the hose from our company)
1.3 Wide range of applications
This pump is particularly suitable for corrosive media with high solid content and viscosity, and has superior self-priming performance. It is widely used in industries such as smelting (gold, silver, copper, lead, zinc, tin, nickel, cobalt, manganese), phosphate compound fertilizers, titanium dioxide, citric acid, rare earths, rare metals, inorganic salts, desulfurization and environmental protection, water treatment, papermaking, painting, etc. The specific applications are as follows:
a. Transportation of drilling mud and organic solvents such as crude oil, gasoline, kerosene, and fuel oil in the petroleum industry;
b. Acid, alkali, salt, phosphoric acid slurry, titanium dioxide slurry, and calcium citrate in the chemical industry; Crystallization liquid, suspension liquid, latex, resin, soft mud, and various material liquids;
c. Slurry transportation and rare metal liquid transportation in the smelting industry;
d. Drug delivery in the pharmaceutical industry;
e. Transportation of mud, lime slurry, and impurities in the water treatment and desulfurization industry;

VI Handling, installation, use, and maintenance of pumps
6.1 Pump Handling and Installation
a. After receiving the equipment, the user should check whether the equipment, spare parts, random files, etc. are complete according to the packing list;
b. When transporting, use the lifting ring screws on the pump casing and the lower part of the motor as the focus points, and handle them gently without significant vibration or impact.
c. The pump should be installed in a spacious and easy to maintain area, with a flat foundation.
d. The inner diameter of the inlet and outlet pipelines of the pump should not be less than the specified requirements. For the convenience of maintenance, a valve can be installed in the outlet pipeline of the pump when using suction working condition; When using reverse flow conditions, valves can be installed in both the inlet and outlet pipelines of the pump, but all valves must be fully opened when the pump is in operation.
e. When the viscosity of the conveyed medium is high (>10000 centipoise), the inlet pipeline should be as short as possible and reverse flow conditions should be adopted.
f. When the pump is installed on a hard pipeline, it is best to load a hose of about 1.5m at the inlet and outlet of the pump to reduce pump pulsation and facilitate pump maintenance.
g. The weight of the inlet and outlet pipelines themselves cannot be directly borne by the inlet and outlet joints of the pump. Additional supports should be installed to prevent damage to the inlet and outlet joints.
h. As long as it is well coordinated with the direction of the motor, the inlet and outlet ends of the pump can be interchanged, and can be flexibly adjusted according to the needs during installation.
i. If the conveyed medium contains sharp or oversized solids, a filtering device should be installed at the inlet end of the pump.
6.2 Pump Operation
Before the pump starts working, please make the following preparations before starting up:
a. Check if the lubricating oil in the reducer inside the pump chamber is sufficient.
b. Check whether the inlet and outlet pipelines of the pump are installed and fixed properly, and whether the bolts at each flange are tightened.
c. Check if all inlet and outlet valves of the pump have been opened.
d. Press the start and stop buttons, jog the pump, check if the motor direction matches the inlet and outlet of the pump, and also check if the pump is stuck.
After the above checks are correct, the machine can be started for trial operation. When there are no abnormalities in all aspects, it can be put into normal operation.
6.3 Maintenance and upkeep of pumps
a. Regularly check the lubricating oil in the pump chamber and reducer. The lubricating oil in the pump chamber is usually replaced by replacing the hose (the lubricating oil in the pump chamber is glycerin). The reducer should be replaced regularly according to its instructions (lubricating oil is N46 mechanical oil).
b. After 15-20 days of continuous operation, the pump can remove the hose, rotate it 90 °, and then reinstall it, which can significantly extend the service life of the hose.
c. There should be no sharp or large solids in the conveyed medium, otherwise it will affect the service life of the hose.
d. Regularly check whether the connecting bolts and screws are loose.
e. Before the pump is stopped for a long time, it should be run idle for a few minutes to empty the medium in the hose, or necessary cleaning should be carried out with clean water.
f. When transporting media that are prone to crystallization, the medium in the hose should be emptied or cleaned with clean water before stopping the machine.
g. The coaxiality of the coupling should be checked regularly.
Special attention: 1 When this pump is in operation, all inlet and outlet valves should be opened, otherwise it may cause faults such as hose rupture and motor damage. If the conveyed medium generates hard sediment, it must be rinsed with clean water before shutdown, otherwise it may cause faults such as cracking of the impeller, coupling, and damage to the motor during the next startup!
