VC-280 and VC-380
These two pumps feature exchangeable rotors with either 2 or 3 rollers providing lower pulsation, higher flow rates or elevated differential pressures. These pumps are supplied with the rotor that accepts 1.6 mm ID tubing. One pump is supplied with the 2 roller rotor and the other is supplied with the 3 rotor roller. They both have a safety cutout feature that stops the rotation of the rotor when the rotor cover is opened. Using standard tubing they provide flow rate ranges from 1.6 to 5,000 ml/minute with a differential pressure of 1.5 bar (22 PSI)*.
VC-360
This pump features 3 convex rollers providing lower pulsations than the other two pumps. Its rotor is not interchangeable with other rotors. It has a hinged tube-bed with wide opening angle allowing rapid tube change over. It uses standard pump tubing and provides a flow rate range from 0.25 to 1,300 ml/minute with a differential pressure of 1.5 bar (22 PSI)*.
VC-Easy-Load
This pump features 3 rollers and an easily accessible pump-head that allows rapid tube change-over. It has a Polysulfone pump-head housing and uses standard pump tubing. This pump provides a flow rate range from 0.23 to 1,600 ml/min with a differential pressure of 1.5 bar (22 PSI)*.
*Note: This is the possible differential pressure using appropriate tubing material; tubing with smaller inner diameters may enable higher pressure.
