Peristaltic pump introduction：

Peristaltic pump is one of the fastest developed positive displacement pump on market. However, many of people still did not familiar with its technical theories and merits. Peristaltic also called tubing pump. During the past days, this kind of pump nearly applied to lab. But after the redesign, the flow speed and pressure are advanced. Nowadays, large abundant of peristaltic pump have already applied to chemical processes control and production area.

The wide use of peristaltic pump attribute to its design which used the motor to drive a group of rollers in achieving its running. The rollers on the rotor move across the tubing, pushing the fluid. The tubing behind the rollers recovers its shape, creates a vacuum, and draws fluid in behind it, finished its transportation. For only pump tubing transfer the fluid, this kind of pump is easy and convenient in maintenance and cleanness.

Such design brings several kinds of advantages. Peristaltic pump can apply to all difficult and complicated application area. Advantages as follow

◆Pollution free		◆Convenient in operating
◆Less maintenance		◆Automatic suction
◆Various kind of tuning materials in applying		◆Soft pump transferring process
◆Transfer liquids, gases, extender and emplastic fluid		◆High efficiency in operating

Flow rates Max flow rate? Flow range: BT50 (0.002-23ml/min) BT100/BL100 (0.0006-290ml/min) BT300/BL300 (0.012-1200ml/min) JT360 (0.3-45L/min) Flow precision? After adjustment, the flow rate error range is less than 0.5%. If using the optional, flow rate error range is less than 1%, can meet the general meet. What kind of affection does viscosity affect on fluidness? The fluidity all according with the water’s as the baseline. The viscosity of fluid is in contrast with its flow rate. Pump head What’s the maximum pressure? The pressure is depend on the pump tubing, generally, the maximum pressure continuous is 40psig (2.7 bar), Maximum pressure intermittent is 25 psig (1.7 bar)., the maximum pressure continuous is 100psig of teflon pump head during operation. What’s the maximum entrance pressure? Actually the pressure is depends on the tubing inside diameter, wall thickness and materials. In normal situation, the input maximum pressure is 40psig (2.7 bar), the maximum pressure continuous is 100psig of teflon pump head during operation. What’s the maximum suction lift? The maximum suction lift up to 29 feet water column Does check value needed? No. Our particular bump body system released such need. Can prefluid pump idling? Yes. It can transfer gas, liquid and multi-mixed fluid. But gas transfer is not suitable for our PTFE pump head, because it may over-heat during racing. Does prefluid pump auto-sucking? Yes. It can produce over 26 feet mercury column(660mm) vacuum.. Does prefluid pump belong to positive displacement? Yes. Water flow rate is proportional to rotor speed. (within the limits of driver’s max capacity) Does prefluid pump belong to non-siphoning? Yes. At least one roller will move across the tubing at anytime and creates a vacuum which prevent the suction. Does prefluid pump transfer pasty fluid or abrasive liquor? Yes. But the available transferring ceiling limit value of viscosity and granularity depend on the tubing inside diameter. Why provide so many pump head types and pump tubing size? Because in most possible applied situation, we can get the suitable fluid transportation at optimal speed. Does reversed transportation be allowed? Yes. All specifications remain the same under clockwise or counterclockwise. Pump tubing How was the importance of pump tubing? Tubing equals to the pump heart of normal pump. Its restitution creates suction lift Its strength resists pressure Its flex resistance determines pumping life Its inside diameter decides the flow rate Its wall thickness controls pumping efficiency. What’s the suitable temperature range of pump tubing? The best temperature range: (0-40℃) The undertake temperature range of tubing : (-73-232℃) The undertake max temperature range of pump tube: (-100-110℃) How many factors does tubing type affect the tubing life? Pump tubing speed and undertake pressure, tubing material and chemical compatibility, the abradability of fluid Which kind of tubing material has the longest life? Pump tubing degression: NORPRENE tube, PHARMED tube, TYGON LFL tube, silicon tube, TYGON silicon tube, C-FLEX tube, TYGON and VITON tube How was the relationship between the speed and tubing life? Pump tube life is in contrast with speed, lower the speed, longer the pump life. How about the compatibility between tubing and food? Can it endure the disinfection? Very well, some part of pump materials accord with MSF, FDA, USDA’s related criterion and demand of food transportation Yes, lots of material can undertake Does the tubing change easily? Yes, very easy. Pump tubing with easy change type pump head, easy change typeⅡpump head, high efficiency pump head, block pump head, quick install pump head can quick and convenient in changing. Driver Does one driver can bring multi-head? Of course, it can. Discretional (2 or 4 in general) standard pump head or easy installment can be bind together at any combination method. Is there any more driver pattern in selecting? Yes. Our engineering department will customize, design and produce a kind of driver or OEM driver accord with your need if in large purchasing.
