Leading A-Series engine specialist since 1981
High-capacity water pump with large impeller and superior quality bearing for competition and fast road applications. This high quality pump helps to reduce cavitation at high RPM and is a direct replacement for the vast majority of A-Series/A-plus engines.
Available with or without bypass connection depending on your cylinder head configuration. The pumps can also be supplied with an MED High Performance upgraded gasket, made from a special aramid fibre with nitrile rubber bonding.
For race usage we would recommend the MED Alloy Water Pump Pulley.
These will not fit early 850 or 997cc Cooper engines.
