Product code: AB28
On pump tube of using life: peristaltic pump tube belongs to supplies, using a time Hou on will wear, led to flow inconsistent, need for replaced, pump tube life and fluid media, link temperature, running speed, work Shi long, intermittent Shi long is closely related to, hard to out exact of using life, I company provides of pump tube life is in corresponding conditions Xia of test results, only as reference.
Application of pump tube: wall thickness of the applied 1.6mm, 9.6mm od tubing, no Te-te.CN requires the standard pump tube: 4.8*8. Tubing material: silicone/corrosion-resistant composite rubber
Reasonable velocity: 4.8*8 pump tube, pump head flow per revolution: 1.75 ml, recommended speed is less than 400 r/min, suggested flow rate less than 380 ml/min (with shorter working hours, to full heat, if necessary, design a top speed to 500 cycles/min)
Pump selection: general standard pump tube 3.2*6.4, 4.8*8, 6.4*9.6
Wheel size: rotor wheel number 2
Cover color: transparent yellow, transparent red, transparent blue, transparent green pure transparent
Installation: there are two types of end of pump installation
Optional voltage: 6 v DC geared motor, 12V, 24V, 6-24V stepper motor, synchronous motor 110V, 220V (Special voltages can be customized)
Motor power: DC geared motor about 10W, 30W 42 stepper motor, 50 motor 10W
Product weight: pump head about 100 g, DC geared motor by about 134 grams, 282 g 42 stepping motor, 50 motor 188 g
Shell material: PC plastic (polycarbonate)
Roller material: plastic POM (polyoxymethylene)
Motor selection: DC geared motor, 42-step motor, synchronous motor

Notes on the motor:
DC gear motor: low cost, easy to use, does not require driving circuitry, then turn
Stepper motors: the high cost of motor requires a specific drive and control circuit of circuit, long service life and high precision
Synchronous electric motors: low cost, can directly use the 220V domestic supply.

Pump head on the wheel size:
Roller pump head higher the more precision is wrong, accuracy of the pump head and the wheel are not necessarily related, precision of the pump head and pump head material, Machining accuracy, deformation. Roller pump head number, is the pump head according to the rotor arc length to determine the effective movement.
Roller pump head is wrong the more the number, the better, less number wheels should be the better, at the request of the same flow rate, wheel, the more the roll of tubing more frequently, the greater resistance of the rotor, direct impact on pump and motor life. (Increased from 2 wheel to 4 wheel, increases the rotational resistance of 1 time and the number of pump tube rolling, tubing life expectancy declined by almost half)

Pump tube diameter 3.2mm diameter 6.4mm, pump head turns every round 0.75ml
