Q:Does the S-35 BF pump need lubrication? Thanks.John Reddy | Sunday, October 7, 2012

A:
According to the manufacturer: The seal bearing assembly should be lubricated at the beginning of each heating season with a non-detergent type oil. The motor does not require any lubrication due to the unique "maintenance-free" motor used by Armstrong Pumps for all its circulator products. Thanks!
