P625 Peristaltic Pumps nstech’s revolutionary P625 peristaltic pumps—quite possibly the smallest on the market—deliver flow performance typically found only in larger, more power-hungry pumps. They are ideal for any fluid transfer application where size, power efficiency, and precision are important. meability and pressure rating. If you need 2 channels this will further narrow your choice of tube sets. 3. Narrow your choices down to one motor type and one tube set size (or a few different tube sets if you are not sure of your flow rate requirements). Check the tube set chart to select the pump and tube set part numbers for ordering. A pump's part number is configured as follows: P625/[motor type].[roller size]. Note that the high durometer PharMed®, Tygon® and Viton® tubes require a different size pump roller than the softer silicone and C-FLEX®. Dual tubes and high durometer tubing should be used with the P625/66 model only. (Please contact Instech for special lower flow rate models that can be used with dual or high-durometer tubing.) 4. Contact us for a quote. Be sure to include the pump and tube set part numbers and the quantities in which you are interested. In general the P625/900 and P625/275 models are less expensive than the 10K and 66 models. The prices of all pump models decline with order quantity. Instech sells these pumps directly to customers all over the world. $ Features Flow rates from 0.0007 to 19 ml/min. Configure the pump with one of four Swiss-made motor and gearhead assemblies, and one of range of pump tube sizes to best match your particular low-flow application. The specially contoured, precision machined pump head minimizes pulsations and improves accuracy. Precise bi-directional speed control. Built-in circuitry provides accurate, linear flow rate control over a 10:1 range, requiring only a single supply and an analog control voltage. The circuitry compensates for torque changes to maintain constant motor speed. Low power, low noise operation. Typically drawing between 25 and 75 mA, this pump is well-suited for battery powered applications. Its all-analog design minimizes EMI. Easy-to-use tube sets. Tube sets can be installed and removed in seconds. They are available in a range of sizes and materials, and all but the largest tubing sizes are available with two channels.

Determine which pump motors function within your desired flow rate range. The 10K:1 motor delivers the lowest flow rates, the 66:1 the highest. There is significant overlap based on tube sets sizes so there will usually be a range of pumps models that could work. 2.

P625 Pump Tube Sets The range of tube sets and compatible pump models are shown in the table below. When specifying a tube set, create a part number as shown below. For example, “P625/TS031S” signifies a one channel .031” ID silicone tube set. The standard length is 1ft (30.5 cm). For orders of fewer than 100 pieces tube sets are sold in packages of five. For orders over 100 pieces bulk packaging is available. P625/TS[D]031S Tube material (S=silicone, C=C-FLEX®, P=PharMed®, T=Tygon® F-4040A, L=Tygon® LFL, V=Viton®) Tube inner diameter in thousandths of an inch Indicates dual channel tube...
