Gentle Pumping Pump Heads
These pump heads provide gentle pumping action and are suitable for
many applications, including cell suspensions.
The model PRO-280 pump head is gentle enough to use for highly
viscous liquids with concentrated viable cells. Comparisons to gear,
piston and centrifugal pumps proved that peristaltic pumps are the
only suitable and sterilizable pump system for gently pumping media
containing living cells.

KEY FEATURES
Unique convex rollers cause minimal cell lysis
Installs rapidly
Easily interchanged with other MCP/BVP pump heads
Elevated differential pressures (PRO-281 and PRO-381)
Ideal for mammalian cell inoculating, harvesting or cell
suspension transfers
Suitable for viscous fluids and fluids containing a
high content of sensitive solids
Applications requiring hygienic conditions,
durability and reliability
PRO-280
Coated aluminum pump head
Can be dismantled for cleaning
Stainless steel rollers
Self-centering tube track, allows tube to lie in the optimum
position, which considerably lengthens the tube life
For applications which require hygienic conditions,
reliability and durability
Ideal for use in chemical, biotechnological and
pharmaceutical processes and in food industry
PRO-281
Same as PRO-280 but
For tubing with 2.4 mm wall thickness
Especially recommended for:
Elevated differential pressures
Viscous fluids
PRO-380
Same as PRO-280 but
Less pulsation thanks to 3 rollers
Slightly lower flow rate
PRO-381
Same as PRO-380 but
For tubing with 2.4 mm wall thickness
Especially recommended for:
Elevated differential pressures
Viscous fluids
