Introduction

Thank you for selecting the Watson-Marlow 205BA pumphead.

This pump head is very similar to the 202AA pumphead, but the 502BA has eight driven

rollers giving the benefit of delivering lower pulsation. It is easy-loading, uses the same

range of manifold tubing as the 202AA and is available in 4, 8 and 12 channel versions.

These supplementary instructions should be read in conjunction with either the

202U/AA or 202S/AA operating instruction manual.

Tube range

The tubing used in the 205BA is the same sizes and five materials of manifold tubing

manufactured for the 202AA - please see the relevant page in your manual.

Flow rates

These flow rates were obtained pumping water at 20C with zero suction and delivery

pressures. If flow rate is critical, it should be measured under operating conditions

where the important factors are suction and delivery, temperature and viscosity.

Cassette loading

For safety reasons, all cassettes should be in position in the pumphead during

normal running, even if some do not contain tubing.

Do not place fingers in the pumphead

Pumphead care and maintenance

When the pumphead needs cleaning, switch the drive off and isolate it from the mains.

Withdraw the cassettes from the pumphead and remove the tubing. Wash the cassettes

in water and mild detergent. If fluid has been spilled into the pumphead, removal of the

pumphead from the drive will make cleaning easier. Periodically, inspect all moving

parts for wear and ensure all bearings and rollers are free to rotate.
