Pro-280
  • Can be dismantled for cleaning - ideal for applications requiring hygienic conditions.
  • Convex rollers and concave tube-bed help maintain the integrity of cellular material being pumped.
  • Self-centering tube-track lengthens tubing life.
  • 2 st. steel rollers (higher max. flow rate but more pulsation than with 3 rollers).
  • Coated aluminium pump head.
  • For tubing with 1.6 mm wall thickness.
  • 1.5 bar (22 psi) differential pressure.*

Pro-281 same pump head as Pro-280, but:
  • For tubing with 2.4 mm wall thickness.
  • 2.5 bar (36 psi) differential pressure.*

Pro-380 same pump head as Pro-280, but:
  • 3 st. steel rollers (less pulsation but lower max. flow rate than with 2 rollers).

  • 2.5 bar (36 psi) differential pressure.*

Easy-Load® II
  • Adjustable pressure setting.
  • Automatic tubing retention.
  • PPS housing.
  • Rotor with 4 st. steel rollers for less pulsation.
  • For tubing ID from 1.6 to 8.0 mm with 1.6 mm wall thickness.
  • 0.7 bar (10 psi) differential pressure.*

The flow rates are based on a drive speed of 1 to 240 min-1. For min. flow rate for BVP Standard drive, multiply the flow rate at 1 min-1 by 2.4. Approx. values are determined with water, at 22 °C, no differential pressure and Tygon® tubing.
